[0025] Hereinafter, the tracker modules according to embodiments 1 to 4 will be described with reference to the accompanying drawings. The drawings referred to in the following embodiments are schematic diagrams, and the size, thickness, and proportions of each component in the drawings may not reflect the actual size proportions.

[0026] (Implementation Method 1)

[0027] (1) Tracker module

[0028] Referring to the accompanying drawings, the structure of the tracker module 1 according to Embodiment 1 will be described.

[0029] like Figure 3 As shown, the tracker module 1 according to Embodiment 1 is configured to output a power supply voltage V1 to a plurality of (four in the example) first power amplifiers 81. One tracker component 3 of the tracker module 1 corresponds to a plurality of communication frequency bands. The plurality of first power amplifiers 81 are configured to amplify a first transmitted signal (high-frequency signal) when a power supply voltage V1 is applied to an amplifying element (not shown). The plurality of first power amplifiers 81 amplify transmitted signals from mutually different communication frequency bands.

[0030] like Figure 4 As shown, the tracker module 1 is used, for example, in the communication device 9. More specifically, the tracker module 1, together with a plurality of first power amplifiers 81 included in the high-frequency module 8, is used in the communication device 9.

[0031] The communication device 9 is, for example, a mobile phone like a smartphone. However, the communication device 9 is not limited to mobile phones; it could also be, for example, a wearable terminal like a smartwatch. The high-frequency module 8 is, for example, a module compatible with 4G (fourth-generation mobile communication) standards, 5G (fifth-generation mobile communication) standards, etc. The 4G standard is, for example, the 3GPP (Third Generation Partnership Project) LTE (Long Term Evolution) standard. The 5G standard is, for example, 5G NR (New Radio). The high-frequency module 8 is, for example, a module compatible with carrier aggregation and dual connectivity.

[0032] The communication device 9 performs communication across multiple communication frequency bands. More specifically, the communication device 9 transmits signals across multiple communication frequency bands and receives signals across multiple communication frequency bands.

[0033] The transmitted and received signals across multiple communication frequency bands are partly FDD (Frequency Division Duplex) signals. However, the transmitted and received signals across multiple communication frequency bands are not limited to FDD signals; they can also be TDD (Time Division Duplex) signals. FDD is a wireless communication technology that allocates different frequency bands for transmission and reception. TDD is a wireless communication technology that allocates the same frequency band for transmission and reception, and switches between frequencies according to time intervals.

[0034] like Figure 1 as well as Figure 2 As shown, the tracker module 1 according to Embodiment 1 includes a substrate 2, a tracker component 3, and multiple (40 in the example) external connection terminals 5. The tracker module 1 is connected, for example, to a device equipped with a high-frequency module 8 (see Figure 8). Figure 4 The battery (not shown) of the terminal, etc., supplies battery voltage to the tracker module 1.

[0035] Here, when the first power amplifier 81 amplifies the transmitted signal using the power supply voltage V1 from the tracker module 1, the envelope tracking method (hereinafter referred to as "ET method") is used.

[0036] The ET method is a method of varying the amplitude level of the power supply voltage to the amplifying element of a power amplifier based on the amplitude of the envelope of a high-frequency signal. More specifically, the ET method detects the envelope of the amplitude of the transmitted signal (high-frequency signal) input to the amplifying element of the power amplifier and varies the amplitude level of the power supply voltage to the amplifying element accordingly. By using the ET method, power loss can be reduced compared to a constant power supply voltage amplitude level, thus achieving higher efficiency.

[0037] In the ET mode, there are analog envelope tracking mode (hereinafter referred to as "analog ET mode") and digital envelope tracking mode (hereinafter referred to as "digital ET mode").

[0038] Analog ET mode continuously detects the envelope of the amplitude of the transmitted signal (high-frequency signal) input to the amplification element of the power amplifier, and changes the amplitude level of the power supply voltage to the amplification element based on the continuously detected envelope. In analog ET mode, because the envelope is continuously detected, the amplitude level of the power supply voltage changes continuously.

[0039] In the case where the analog ET method is used in embodiment 1, the tracker module 1 continuously detects the envelope of the amplitude of the first transmitted signal input to the first power amplifier 81 for each of the multiple first power amplifiers 81, and outputs the power supply voltage V1, whose amplitude level changes continuously according to the continuously detected envelope, to the first power amplifier 81.

[0040] Digital Echo Echo (ET) mode discretely detects the envelope of the amplitude of the transmitted signal (high-frequency signal) input to the amplification element of a power amplifier, and adjusts the amplitude level of the power supply voltage to the amplification element according to the discretely detected envelope. In digital ET mode, the amplitude level of the transmitted signal is detected discontinuously at regular intervals, and the detected amplitude level is quantized. Because the envelope is detected discretely in digital ET mode, the amplitude level of the power supply voltage changes discretely.

[0041] In the implementation method 1, where the digital ET method is used, the tracker module 1 discretely detects the envelope of the amplitude of the first transmitted signal input to the first power amplifier 81 for each of the multiple first power amplifiers 81, and outputs the power supply voltage V1, which is discretely changed according to the discretely detected envelope, to the first power amplifier 81.

[0042] In tracker module 1, such as Figure 1 as well as Figure 3As shown, the plurality of external connection terminals 5 include a plurality of (four in the example) first output terminals 6. The plurality of first output terminals 6 correspond to a plurality of first power amplifiers 81. Each first output terminal 6 is disposed on the second main surface 22 of the substrate 2 and connected to the corresponding first power amplifier 81. In addition, each first output terminal 6 is connected to the tracker component 3.

[0043] like Figure 1 As shown, when viewed from the thickness direction of the substrate 2, the first output terminals 6A and 6D of the plurality of first output terminals 6 overlap with the tracker component 3.

[0044] This allows the first output terminals 6A and 6D of the first power amplifier 81 to be connected to the tracker component 3 within the configuration area of ​​the tracker component 3. As a result, the wiring length between the first output terminals 6A and 6D of the first power amplifier 81 and the tracker component 3 can be shortened.

[0045] (2) Components of the tracker module

[0046] Hereinafter, with reference to the accompanying drawings, the constituent elements of the tracker module 1 according to Embodiment 1 will be described.

[0047] (2.1)Substrate

[0048] Figure 1 as well as Figure 2 The substrate 2 shown is separate from the substrate (not shown) on which a plurality of first power amplifiers 81 are disposed. The substrate 2 has a first main surface 21 and a second main surface 22. The first main surface 21 and the second main surface 22 are opposite to each other in the thickness direction of the substrate 2.

[0049] The substrate 2 is, for example, a low-temperature co-fired ceramic (LTCC) substrate, a high-temperature co-fired ceramic (HTCC) substrate, a component-embedded substrate, a substrate with a redistribution layer (RDL), or a printed circuit board, having a multilayer dielectric structure.

[0050] (2.2) Tracker components

[0051] like Figure 2 as well as Figure 3As shown, the tracker component 3 is disposed on the first main surface 21 of the substrate 2 and generates a power supply voltage V1. The tracker component 3 is configured to output the power supply voltage V1 to a plurality of (four in the example) first power amplifiers 81. More specifically, the tracker component 3 generates a power supply voltage V1 with an amplitude level corresponding to the envelope of the amplitude of the first transmitted signal, and outputs the generated power supply voltage V1 to each of the first power amplifiers 81.

[0052] The tracker component 3 has multiple (36 in the example) terminals 31. These terminals 31 include input terminals for power control signals. The input terminals are connected to the signal processing circuit 92 (see reference 92). Figure 4 The power control signal is input from the signal processing circuit 92. The tracker component 3 generates a power supply voltage V1 based on the power control signal input to the input terminal. At this time, the tracker component 3 changes the amplitude of the power supply voltage V1 based on the power control signal from the signal processing circuit 92. In other words, the tracker component 3 performs envelope tracking to generate a power supply voltage V1 that varies according to the envelope of the amplitude of the high-frequency signal output from the signal processing circuit 92.

[0053] The tracker component 3 outputs power supply voltage V1 to each of the first power amplifiers 81 via the first output terminal 6 through the ET method.

[0054] Tracker component 3 is an integrated circuit such as a semiconductor IC (Integrated Circuit), for example, constructed using CMOS (Complementary Metal Oxide Semiconductor), specifically manufactured via SOI (Silicon on Insulator) process. Tracker component 3 may also be constructed from at least one of GaAs, SiGe, and GaN. Furthermore, the semiconductor material of tracker component 3 is not limited to the materials described above.

[0055] (2.3) External connection terminals

[0056] like Figure 1 As shown, the plurality of external connection terminals 5 include input terminals 51, a plurality of (four in the example) control terminals 52, a plurality of (two in the example) signal terminals 53, and a plurality of (four in the example) first output terminals 6. The plurality of external connection terminals 5 are arranged in a grid pattern, for example, on the second main surface 22 of the substrate 2. Figure 1 In the example, multiple external connection terminals 5 are configured as a 5×8 grid.

[0057] Input terminal 51 is connected, for example, to a device equipped with a high-frequency module 8 (see reference). Figure 4The battery (not shown) of the terminal, etc., supplies the battery voltage to the tracker module 1 and inputs it to the input terminal 51.

[0058] Multiple control terminals 52 are connected to the signal processing circuit 92 (see reference). Figure 4 The signal processing circuit 92 receives power control signals and other signals from its terminals. The signals input to each control terminal 52 are output to the tracker component 3.

[0059] Multiple signal terminals 53 are terminals for inputting envelope differential signals from the signal processing circuit 92. The envelope differential signals input to each set of signal terminals 53 are output to the tracker component 3.

[0060] (2.4) First output terminal

[0061] like Figure 1 as well as Figure 3 As shown, multiple first output terminals 6 are connected to multiple first power amplifiers 81 respectively, and are used to output a power supply voltage V1 from the tracker module 1 to the multiple first power amplifiers 81. More specifically, the multiple first output terminals 6 correspond one-to-one with the multiple first power amplifiers 81, and each first output terminal 6 is used to output the power supply voltage V1 output from the tracker component 3 to the corresponding first power amplifier 81 among the multiple first power amplifiers 81. The power supply voltage V1 output from the tracker component 3 passes through each first output terminal 6. That is, the multiple first output terminals 6 are respectively connected to the tracker component 3 and become the supply path of the power supply voltage V1 to the corresponding first power amplifier 81 among the multiple first power amplifiers 81.

[0062] exist Figure 3 In the example, the first output terminal 6A is used to output the power supply voltage V1 to the first power amplifier 81A. The first output terminal 6B is used to output the power supply voltage V1 to the first power amplifier 81B. The first output terminal 6C is used to output the power supply voltage V1 to the first power amplifier 81C. The first output terminal 6D is used to output the power supply voltage V1 to the first power amplifier 81D.

[0063] Here, "correspondence" refers to the relationship between the first output terminal 6 through which the power supply voltage V1 from the tracker component 3 passes and the first power amplifier 81 that receives the power supply voltage V1. Figure 3 In the example, the first output terminal 6A corresponds to the first power amplifier 81A, the first output terminal 6B corresponds to the first power amplifier 81B, the first output terminal 6C corresponds to the first power amplifier 81C, and the first output terminal 6D corresponds to the first power amplifier 81D. Furthermore, "correspondence" is not limited to a one-to-one correspondence.

[0064] like Figure 1 As shown, multiple first output terminals 6 are disposed on the second main surface 22 of the substrate 2. Figure 3 As shown, each first output terminal 6 is connected to a corresponding first power amplifier 81. Each first output terminal 6 is connected to the tracker component 3. Here, "first output terminal 6 connected to tracker component 3" includes the first output terminal 6 being connected to the tracker component 3 without passing through other components, and the first output terminal 6 being connected to the tracker component 3 via other components. That is, "first output terminal 6 connected to tracker component 3" includes the first output terminal 6 being directly connected to the tracker component 3, and the first output terminal 6 being indirectly connected to the tracker component 3.

[0065] (2.5) Position of the first output terminal

[0066] like Figure 1 As shown, a plurality of first output terminals 6 are disposed on the second main surface 22 of the substrate 2. The first output terminals 6 are connected to the tracker component 3.

[0067] like Figure 1 As shown, a plurality of first output terminals 6 are disposed on the outermost periphery of the second main surface 22 of the substrate 2. That is, when a plurality of external connection terminals 5 are disposed, the first output terminals 6 are disposed at the ends.

[0068] Here, "the first output terminal 6 is disposed on the outermost periphery of the second main surface 22 of the substrate 2" means that the first output terminal 6 is disposed on the second main surface 22 of the substrate 2 at a position where there are no other external connection terminals between the first output terminal 6 and at least one side of the outer edge of the substrate 2. In other words, "the first output terminal 6 is disposed on the outermost periphery of the second main surface 22 of the substrate 2" means that when viewed from the thickness direction of the substrate 2, the first output terminal 6 is disposed at a position where there are no other external connection terminals between the first output terminal 6 and at least one side of the outer edge of the substrate 2. Furthermore, "the first output terminal 6 is disposed on the outermost periphery of the second main surface 22 of the substrate 2" means that in a direction orthogonal to the thickness direction of the substrate 2, the first output terminal 6 is disposed at a position where there are no other external connection terminals between the first output terminal 6 and the outer edge of the substrate 2. For example, "the first output terminal 6 is disposed on the outermost periphery of the second main surface 22 of the substrate 2" means that the first output terminal 6 is disposed at a position where there are no other external connection terminals along the shortest straight line connecting the first output terminal 6 and the outer edge of the substrate 2.

[0069] Therefore, it is easy to connect the first output terminal 6 to the first power amplifier 81. More specifically, on the substrate (mother substrate) for mounting the tracker module 1, by configuring the tracker module 1 so that the first output terminal 6 is close to the first power amplifier 81, the wiring length between the first output terminal 6 and the first power amplifier 81 can be shortened. As a result, compared to the case where the first output terminal 6 is not disposed on the outermost periphery of the second main surface 22 of the substrate 2, it is easier to form a wiring pattern portion for connecting the first output terminal 6 to the first power amplifier 81.

[0070] like Figure 1 As shown, a plurality of first output terminals 6 are arranged on the second main surface 22 of the substrate 2 without being adjacent to each other. More specifically, on the second main surface 22 of the substrate 2, first output terminals 6A, 6B, 6C, and 6D are arranged without being adjacent to each other. Furthermore, the external connection terminals 5 present between the first output terminals 6 are preferably grounded terminals connected to ground.

[0071] Therefore, since the distance between the multiple first output terminals 6 can be increased, the isolation between the multiple first output terminals 6 can be improved compared to the case where they are adjacent to each other.

[0072] Here, "the plurality of first output terminals 6 are configured not to be adjacent to each other" means that the first output terminals 6 are configured such that at least one other external connection terminal 5 exists between the first output terminals 6. Here, "at least one other external connection terminal 5 exists between the first output terminals 6" means that, when viewed from the thickness direction of the substrate 2, at least one of the plurality of line segments connecting any point within one first output terminal 6 to any point within another first output terminal 6 passes through at least a portion of the other external connection terminal 5. Furthermore, viewing from the thickness direction of the substrate 2 means that the substrate 2 and the electronic components mounted on the substrate 2 are projected orthographically onto a plane parallel to the main surfaces (first main surface 21, second main surface 22) of the substrate 2.

[0073] exist Figure 1 In the example, since there are four external connection terminals 5 between the first output terminal 6A and the first output terminal 6B, it can be said that the first output terminals 6A and 6B are not adjacent to each other in a grounded configuration. Furthermore, since there is one external connection terminal 5 between the first output terminal 6B and the first output terminal 6C, it can be said that the first output terminals 6B and 6C are not adjacent to each other in a grounded configuration. And, since there are four external connection terminals 5 between the first output terminal 6C and the first output terminal 6D, it can be said that the first output terminals 6C and 6D are not adjacent to each other in a grounded configuration.

[0074] Furthermore, at least two of the plurality of first output terminals 6 are arranged along two different edges of the substrate 2. Figure 1 In this example, the first output terminal 6A is arranged along the lower edge (first edge) of the substrate 2, the first output terminals 6B and 6C are arranged along the left edge (second edge) of the substrate 2, and the first output terminal 6D is arranged along the upper edge (third edge) of the substrate 2. Therefore, the first output terminals 6A, 6B, and 6C are arranged along different edges of the substrate 2. Furthermore, the first output terminals 6B, 6C, and 6D are arranged along different edges of the substrate 2. Also, the first output terminals 6A and 6D are arranged along different edges of the substrate 2.

[0075] Furthermore, in Embodiment 1, the two edges of the substrate 2, which is provided with at least two first output terminals 6, are opposite each other. Figure 1 In this example, the first output terminal 6A is disposed at the lower edge of the substrate 2, and the first output terminal 6D is disposed at the upper edge of the substrate 2. Therefore, the first output terminals 6A and 6D are disposed at two opposing edges of the substrate 2.

[0076] like Figure 1 As shown, when viewed from the thickness direction of the substrate 2, the first output terminals 6A and 6D of the plurality of first output terminals 6 overlap with the tracker component 3.

[0077] Therefore, the output terminal (not shown) of the tracker component 3 can be connected to the first output terminals 6A and 6D within the configuration area of ​​the tracker component 3. As a result, compared to the case where the first output terminal connected to the first power amplifier does not overlap with the configuration area of ​​the tracker component, the wiring length between the first output terminals 6A and 6D of the first power amplifier 81 and the tracker component 3 can be shortened. More specifically, the wiring length between the first output terminal 6A of the first power amplifier 81A and the tracker component 3, and the wiring length between the first output terminal 6D of the first power amplifier 81D and the tracker component 3 can be shortened.

[0078] (3) Components of the high-frequency module

[0079] Hereinafter, with reference to the accompanying drawings, the constituent elements of the high-frequency module 8 according to Embodiment 1 will be described.

[0080] like Figure 4 as well as Figure 5 As shown, the high-frequency module 8 has multiple (in Figure 4 (Only two are shown in the diagram) First power amplifier 81, multiple (in) Figure 4(Only two are shown in the diagram) First transmitting filters 83, 84; first receiving filters 851, 852; first low-noise amplifiers 861, 862; switch 87; multiple (in...) Figure 4 (Only seven are shown in the figure) External connection terminals 88 and controller 89. The multiple external connection terminals 88 include signal input terminals 881, 882, signal output terminals 883, 884, antenna terminal 885, and terminals 886, 887.

[0081] The high-frequency module 8 amplifies the power of the high-frequency signal (RF signal) output from the RF signal processing circuit 94 (described later) to the level required for transmission to the base station (not shown), and outputs the amplified high-frequency signal.

[0082] (3.1) Power Amplifier

[0083] Figure 4 The first power amplifier 81 shown includes a transistor (amplifying element). The transistor in the first power amplifier 81 is, for example, an NPN transistor, which is an amplifying element that amplifies high-frequency signals when a power supply voltage V1 is applied. The transistor amplifies the high-frequency signal output from the RF signal processing circuit 94. The collector of the transistor is electrically connected to the first output terminal 6 of the tracker module 1 via terminal 886. The emitter of the transistor is at ground potential.

[0084] A power supply voltage V1 is applied to the transistor of the first power amplifier 81. A high-frequency signal output from the RF signal processing circuit 94 is input to the base of the transistor. A tracker module 1 is connected to the collector of the transistor. A power supply voltage V1 controlled according to the amplitude level of the high-frequency signal is applied from the tracker module 1 to the collector of the transistor. In addition, the collector of the transistor is connected to the first transmit filter 83.

[0085] As mentioned above, due to the use of the ET method, the amplitude level of the power supply voltage V1 varies based on the amplitude of the high-frequency signal.

[0086] Here, the first power amplifier 81 is, for example, a power amplifier that amplifies the FDD-based transmission signal. More specifically, the first power amplifier 81 is a power amplifier that amplifies the transmission signal in the intermediate frequency band (IF band). The first power amplifier 81 is, for example, the power amplifier corresponding to Band 30. Since the first power amplifier 81 is a power amplifier for FDD, in the high-frequency module 8, the first power amplifier 81 operates with the power supply voltage V1, and while transmitting, it also receives. Therefore, it is preferable that the higher harmonic components (noise components) of the power supply voltage V1 are small.

[0087] As mentioned above, due to the use of the ET method, the amplitude level of the power supply voltage V1 varies based on the amplitude of the high-frequency signal.

[0088] (3.2) Transmitting Filter

[0089] like Figure 4 As shown, the first transmit filter 83 is a transmit filter for the communication frequency band that allows high-frequency signals to pass through. The first transmit filter 83 is disposed in the path between the first power amplifier 81A and the antenna terminal 885 in the transmit path. More specifically, the first transmit filter 83 is disposed in the path between the first power amplifier 81A and the switch 87. The first transmit filter 83 allows the high-frequency signal amplified by and output from the first power amplifier 81A to pass through. The transmit path is the path that connects the signal input terminal 881 and the antenna terminal 885 for transmitting high-frequency signals from the antenna 91.

[0090] like Figure 4 As shown, the first transmit filter 84 is a transmit filter for the communication frequency band that allows high-frequency signals to pass through. The first transmit filter 84 is disposed in the path between the first power amplifier 81B and the antenna terminal 885 in the transmit path. More specifically, the first transmit filter 84 is disposed in the path between the first power amplifier 81B and the switch 87. The first transmit filter 84 allows the high-frequency signal amplified by and output from the first power amplifier 81B to pass through. The transmit path is the path that connects the signal input terminal 882 and the antenna terminal 885 for transmitting high-frequency signals from the antenna 91.

[0091] Furthermore, the filter through which the high-frequency signal output from the first power amplifier 81A passes is not limited to a transmitting filter like the first transmitting filter 83, but can be a duplexer that includes both a transmitting filter and a receiving filter, or a multiplexer that includes three or more filters.

[0092] Furthermore, the filter through which the high-frequency signal output from the first power amplifier 81B passes is not limited to a transmitting filter like the first transmitting filter 84, but can be a duplexer that includes both a transmitting filter and a receiving filter, or a multiplexer that includes three or more filters.

[0093] (3.3) Switch

[0094] like Figure 4 As shown, switch 87 is a switch that switches the path connected to antenna terminal 885. In other words, switch 87 is a switch that switches the filter connected to antenna terminal 885 from a plurality of filters including first transmit filter 83, first transmit filter 84, first receive filter 851, and first receive filter 852.

[0095] Switch 87 is, for example, a switch IC (Integrated Circuit). For example, switch 87 is controlled by signal processing circuit 92, described later. Switch 87 switches the connection state according to the control signal from RF signal processing circuit 94 of signal processing circuit 92.

[0096] (3.4) Antenna terminal

[0097] like Figure 4 As shown, antenna terminal 885 is the terminal for connecting to antenna 91, which will be described later. High-frequency signals from high-frequency module 8 are output to antenna 91 via antenna terminal 885. Conversely, high-frequency signals from antenna 91 are output to high-frequency module 8 via antenna terminal 885.

[0098] (3.5) Controller

[0099] Figure 5 The controller 89 shown is the PA control circuit that controls the first power amplifier 81. The controller 89 controls the magnitude and timing of the bias current (or bias voltage) supplied to the first power amplifier 81 by receiving control signals from the RF signal processing circuit 94.

[0100] (4) Communication device

[0101] Next, with reference to the accompanying drawings, the communication device 9 using the tracker module 1 will be described.

[0102] like Figure 4 As shown, the communication device 9 includes a tracker module 1, a high-frequency module 8, an antenna 91, and a signal processing circuit 92.

[0103] (4.1) Antenna

[0104] like Figure 4 As shown, antenna 91 is connected to antenna terminal 885 of high-frequency module 8. Antenna 91 has the function of radiating high-frequency signals (transmit signals) output from high-frequency module 8 as radio waves, and the function of receiving high-frequency signals (receive signals) as radio waves from the outside and outputting them to high-frequency module 8.

[0105] (4.2) Signal processing circuit

[0106] like Figure 4 As shown, the signal processing circuit 92 includes a baseband signal processing circuit 93 and an RF signal processing circuit 94. The signal processing circuit 92 outputs a high-frequency signal to the high-frequency module 8. That is, the signal processing circuit 92 outputs a transmission signal to the first power amplifiers 81A and 81B.

[0107] The baseband signal processing circuit 93, for example, is a BBIC (Baseband Integrated Circuit), which performs signal processing on high-frequency signals. The frequency of high-frequency signals is, for example, from several hundred MHz to several GHz.

[0108] The baseband signal processing circuit 93 generates I-phase and Q-phase signals based on the baseband signal. The baseband signal can be, for example, an externally input audio signal or image signal. The baseband signal processing circuit 93 performs IQ modulation processing by combining the I-phase and Q-phase signals and outputs a transmit signal. At this time, the transmit signal is generated as a modulated signal (IQ signal) after amplitude modulation of a carrier signal at a specified frequency with a period longer than the period of the carrier signal. The modulated signal output from the baseband signal processing circuit 93 is output as the IQ signal. The IQ signal refers to a signal that shows amplitude and phase on the IQ plane. The frequency of the IQ signal is, for example, around several MHz to several tens of MHz.

[0109] The RF signal processing circuit 94 is, for example, an RFIC (Radio Frequency Integrated Circuit) that performs signal processing on high-frequency signals. For example, the RF signal processing circuit 94 performs prescribed signal processing on the modulated signal (IQ signal) output from the baseband signal processing circuit 93. More specifically, the RF signal processing circuit 94 performs up-conversion and other signal processing on the modulated signal output from the baseband signal processing circuit 93, and outputs the processed high-frequency signal to the high-frequency module 8. Furthermore, the RF signal processing circuit 94 is not limited to performing direct frequency conversion from the modulated signal to the high-frequency signal. The RF signal processing circuit 94 can also convert the modulated signal into an intermediate frequency (IF) signal and generate a high-frequency signal based on the converted IF signal.

[0110] The signal processing circuit 92 outputs a power control signal to the tracker component 3 of the tracker module 1. The power control signal is a signal containing information related to changes in the amplitude of the high-frequency signal, and is output from the signal processing circuit 92 to the tracker module 1 to change the amplitude of the power supply voltage V1. The power control signal may be, for example, an I-phase signal and a Q-phase signal.

[0111] (5) Details of the tracker module

[0112] Next, refer to Figure 5 as well as Figure 6 The details of the tracker module 1 involved in Implementation Method 1 will be described.

[0113] like Figure 5 as well as Figure 6As shown, the tracker module 1 includes a pre-tuner circuit 10, a switched capacitor circuit 20, an output switch circuit 30, and a DC power supply 50.

[0114] The tracker module 1 supplies a power supply voltage V1, which has a power supply voltage level selected from multiple discrete voltage levels based on the envelope signal, to the first power amplifier 81.

[0115] The pre-regulator circuit 10 includes a power inductor and a switch. The power inductor is an inductor used for boosting and / or bucking (boost, buck, or buck-boost) DC voltages. The power inductor is connected in series with the DC path. The pre-regulator circuit 10 uses the power inductor to convert the voltage. The pre-regulator circuit 10 described above can also be referred to as a magnetic regulator or a DC (Direct Current) / DC converter. Furthermore, the power inductor can also be connected (in parallel) between the series path and ground.

[0116] In addition, the pre-tuner circuit 10 may not have a power inductor. For example, it may be a circuit that performs boost and / or buck (boost, buck, or buck-boost) by switching capacitors respectively configured in the series arm path and the parallel arm path of the pre-tuner circuit 10.

[0117] The switched capacitor circuit 20 includes multiple capacitors and multiple switches, and is capable of generating multiple voltages, each with multiple discrete voltage levels, based on the voltage output from the pre-adjuster circuit 10. The switched capacitor circuit 20 is also sometimes referred to as a switched-capacitor voltage balancer.

[0118] The output switching circuit 30 selects at least one of the multiple voltages generated by the switched capacitor circuit 20 and outputs it to the first power amplifier 81 based on the digital control signal corresponding to the envelope signal.

[0119] DC power supply 50 supplies DC voltage to preseter circuit 10. DC power supply 50 may be a rechargeable battery, for example, but DC power supply 50 is not limited to a rechargeable battery.

[0120] Furthermore, tracker module 1 may not include at least one of the pre-tuning circuit 10 and DC power supply 50. For example, tracker module 1 may not include DC power supply 50. Additionally, any combination of pre-tuning circuit 10, switched capacitor circuit 20, and output switching circuit 30 can be integrated into a single circuit. Figure 6 The detailed circuit structure example of tracker module 1 will be described later.

[0121] (5.1) Circuit structure of the tracker module

[0122] Next, refer to Figure 6 The circuit structure of the pre-tuning circuit 10, the switched capacitor circuit 20, and the output switch circuit 30 included in the tracker module 1 will be described.

The pre-tuner circuit 10, the switched capacitor circuit 20, and the output switch circuit 30 can be installed using a variety of circuit configurations and any of the circuit techniques employed. Therefore, the descriptions of the circuits provided below should not be interpreted in a limited way.

[0124] (5.2) Switched capacitor circuit

[0125] like Figure 6 As shown, the switched capacitor circuit 20 includes multiple (6 in the example) capacitors C11 to C16, multiple (4 in the example) capacitors C21 to C24, multiple (16 in the example) switches S11 to S14, S21 to S24, S31 to S34, S41 to S44, and control terminal 120.

[0126] Control terminal 120 is an input terminal for digital control signals. That is, control terminal 120 is a terminal for receiving digital control signals for controlling the switched capacitor circuit 20. The digital control signals received via control terminal 120 are, for example, source-synchronous control signals that transmit data signals and clock signals. However, the aforementioned digital control signals are not limited to source-synchronous control signals. For example, the aforementioned digital control signals could also be clock-embedded control signals.

[0127] Multiple capacitors C11 to C16 function as fast capacitors (transfer capacitors). That is, multiple capacitors C11 to C16 are used to boost or buck the voltage supplied from the pre-adjuster circuit 10. More specifically, multiple capacitors C11 to C16 cause charge to move between capacitors C11 to C16 and nodes N1 to N4 to maintain voltages V11 to V14 (voltages relative to ground potential) at the four nodes N1 to N4, satisfying V11:V12:V13:V14 = 1:2:3:4. The multiple voltages V11 to V14 are equivalent to multiple voltages, each with multiple discrete voltage levels. Voltage V11 is the voltage at node N1, voltage V12 is the voltage at node N2, voltage V13 is the voltage at node N3, and voltage V14 is the voltage at node N4.

[0128] Capacitor C11 has two electrodes (first electrode and second electrode). One of the two electrodes of capacitor C11 (first electrode) is connected to one end (first terminal) of switch S11 and one end (first terminal) of switch S12. The other electrode of capacitor C11 (second electrode) is connected to one end (first terminal) of switch S21 and one end (first terminal) of switch S22.

[0129] Capacitor C12 has two electrodes (first electrode and second electrode). One of the two electrodes of capacitor C12 (first electrode) is connected to one end (first terminal) of switch S21 and one end (first terminal) of switch S22. The other electrode of capacitor C12 (second electrode) is connected to one end (first terminal) of switch S31 and one end (first terminal) of switch S32.

[0130] Capacitor C13 has two electrodes (a first electrode and a second electrode).

The other electrode of capacitor C13 (the second electrode) is connected to one end (the first terminal) of switch S41 and one end (the first terminal) of switch S42.

[0131] Capacitor C14 has two electrodes (first electrode and second electrode). One of the two electrodes of capacitor C14 (first electrode) is connected to one end (first terminal) of switch S13 and one end (first terminal) of switch S14. The other electrode of capacitor C14 (second electrode) is connected to one end (first terminal) of switch S23 and one end (first terminal) of switch S24.

[0132] Capacitor C15 has two electrodes (first electrode and second electrode). One of the two electrodes of capacitor C15 (first electrode) is connected to one end (first terminal) of switch S23 and one end (first terminal) of switch S24. The other electrode of capacitor C15 (second electrode) is connected to one end (first terminal) of switch S33 and one end (first terminal) of switch S34.

[0133] Capacitor C16 has two electrodes (a first electrode and a second electrode). One of the two electrodes of capacitor C16 (the first electrode) is connected to one end (the first terminal) of switch S33 and one end (the first terminal) of switch S34. The other electrode of capacitor C16 (the second electrode) is connected to one end (the first terminal) of switch S43 and one end (the first terminal) of switch S44.

[0134] The groups of capacitors C11 and C14, C12 and C15, and C13 and C16 can be charged and discharged in a complementary manner by repeating the first and second stages below, respectively.

[0135] Specifically, in the first stage, switches S12, S13, S22, S23, S32, S33, S42, and S43 are turned on. Thus, for example, one electrode of capacitor C12 (the first electrode) is connected to node N3, the other electrode of capacitor C12 (the second electrode) and one electrode of capacitor C15 (the first electrode) are connected to node N2, and the other electrode of capacitor C15 (the second electrode) is connected to node N1.

[0136] On the other hand, in the second stage, switches S11, S14, S21, S24, S31, S34, S41, and S44 are turned on. Thus, for example, one of the two electrodes of capacitor C15 (the first electrode) is connected to node N3, the other electrode of capacitor C15 (the second electrode) and one of the two electrodes of capacitor C12 (the first electrode) are connected to node N2, and the other electrode of capacitor C12 (the second electrode) is connected to node N1.

[0137] By repeating the first and second stages described above, for example, when one of capacitors C12 and C15 is charged from node N2, the other of capacitors C12 and C15 can discharge to capacitor C23. That is, capacitors C12 and C15 can be charged and discharged complementaryly. Capacitors C12 and C15 are a pair of fast capacitors that are charged and discharged complementaryly.

[0138] Furthermore, any one of capacitors C11 to C13 and any one of capacitors C14 to C16, through appropriate switching, can become a pair of fast capacitors that complement each other, performing charging from the node and discharging to the smoothing capacitor, just like the pair of capacitors C12 and C15.

On the other hand, the other end (the second end) of switch S11 is connected to node N3.

[0145] Switch S12 is connected between one of the two electrodes (the first electrode) of capacitor C11 and node N4.

That is, the other end of switch S23 is connected to the other end (second end) of switch S21 and the other end (second end) of switch S32.

[0155] Switch S24 is connected between one of the two electrodes (first electrode) of capacitor C15 and node N3. Specifically, one end (first end) of switch S24 is connected to one of the two electrodes (first electrode) of capacitor C15 and the other end (second electrode) of capacitor C14. On the other hand, the other end (second end) of switch S24 is connected to node N3. That is, the other end of switch S24 is connected to the other end (second end) of switch S11, the other end (second end) of switch S22, and the other end (second end) of switch S13.

[0156] Switch S33 is connected between the other two electrodes (second electrode) of capacitor C15 and node N1. Specifically, one end (first end) of switch S33 is connected to the other two electrodes (second electrode) of capacitor C15 and one of the two electrodes (first electrode) of capacitor C16. On the other hand, the other end (second end) of switch S33 is connected to node N1. That is, the other end of switch S33 is connected to the other end (second end) of switch S31 and the other end (second end) of switch S42.

[0157] Switch S34 is connected between the other two electrodes (second electrode) of capacitor C15 and node N2. Specifically, one end (first end) of switch S34 is connected to the other two electrodes (second electrode) of capacitor C15 and one of the two electrodes (first electrode) of capacitor C16. On the other hand, the other end (second end) of switch S34 is connected to node N2. That is, the other end of switch S34 is connected to the other end (second end) of switch S21, the other end (second end) of switch S32, and the other end (second end) of switch S23.

[0158] Switch S43 is connected between the other electrode (second electrode) of capacitor C16 and ground. Specifically, one end (first end) of switch S43 is connected to the other electrode (second electrode) of capacitor C16. On the other hand, the other end (second end) of switch S43 is connected to ground.

[0159] Switch S44 is connected between the other two electrodes (second electrode) of capacitor C16 and node N1. Specifically, one end (first end) of switch S44 is connected to the other two electrodes (second electrode) of capacitor C16.

[0160] The switches in the first group, comprising switches S12, S13, S22, S23, S32, S33, S42, and S43, and the switches in the second group, comprising switches S11, S14, S21, S24, S31, S34, S41, and S44, complementarily switch on and off. Specifically, in the first stage, the switches in the first group are turned on, and the switches in the second group are turned off. Conversely, in the second stage, the switches in the first group are turned off, and the switches in the second group are turned on.

[0161] For example, in one of the first and second stages, charging is performed from capacitors C11 to C13 to capacitors C21 to C24; in the other of the first and second stages, charging is performed from capacitors C14 to C16 to capacitors C21 to C24. That is, in capacitors C21 to C24, charging is always performed from either capacitors C11 to C13 or capacitors C14 to C16. Therefore, even if current flows rapidly from nodes N1 to N4 to the output switching circuit 30, charge can be replenished rapidly at nodes N1 to N4, thus suppressing potential fluctuations at nodes N1 to N4.

[0162] By operating as described above, the switched capacitor circuit 20 can maintain nearly equal voltages across each of capacitors C21 to C24. Specifically, at the four nodes N1 to N4, voltages V11 to V14 (relative to ground potential) are maintained, satisfying V11:V12:V13:V14 = 1:2:3:4. The voltage levels of V11 to V14 correspond to multiple discrete voltage levels supplied to the output switching circuit 30 through the switched capacitor circuit 20.

[0163] Furthermore, the voltage ratio V11:V12:V13:V14 is not limited to 1:2:3:4. For example, the voltage ratio V11:V12:V13:V14 can also be 1:2:4:8.

[0164] in addition, Figure 6 The structure of the switched capacitor circuit 20 shown is an example, and the structure of the switched capacitor circuit 20 is not limited to... Figure 6 The structure shown. In Figure 6In this circuit, the switched capacitor circuit 20 is configured to supply four discrete voltage levels, but is not limited to supplying four discrete voltage levels. The switched capacitor circuit 20 can also be configured to supply two or more discrete voltage levels. For example, when supplying two discrete voltage levels, the switched capacitor circuit 20 only needs to include capacitors C12 and C15, and switches S21, S22, S31, S32, S23, S24, S33, and S34.

[0165] The switch included in the switched capacitor circuit 20 is contained in the tracker component 3 (see reference). Figure 3 Specifically, the tracker component 3 includes multiple switches S11 to S14, S21 to S24, S31 to S34, and S41 to S44.

[0166] (5.3) Output Switching Circuit

[0167] Next, the circuit structure of the output switch circuit 30 will be described. For example... Figure 6 As shown, the output switch circuit 30 includes multiple (four in the example) input terminals 131 to 134, multiple (four in the example) switches S51 to S54, output terminal 130, and control terminal 135.

[0168] Output terminal 130 is connected to the first power amplifier 81 (see reference). Figure 4 Output terminal 130 is a terminal for supplying a voltage selected from voltages V11 to V14 to the first power amplifier 81.

[0169] Multiple input terminals 131 to 134 are respectively connected to nodes N1 to N4 of the switched capacitor circuit 20. The multiple input terminals 131 to 134 are terminals used to receive voltages V11 to V14 from the switched capacitor circuit 20.

[0170] Control terminal 135 is an input terminal for digital control signals. That is, control terminal 135 is a terminal for receiving a digital control signal representing one of voltages V11 to V14. Output switch circuit 30 controls the on / off state of multiple switches S51 to S54 to select the voltage level indicated by the digital control signal.

[0171] The digital control signal received via control terminal 135 is, for example, two Digital Control Logic (DCL) signals. Each DCL signal is a one-bit signal. A combination of the two one-bit signals represents one of voltages V11 to V14. For example, voltages V11, V12, V13, and V14 are represented by "00", "01", "10", and "11", respectively. Gray code can also be used to represent voltage levels. Furthermore, in the above case, two control terminals are provided to receive two DCL signals. Additionally, the number of DCL signals can be any number, depending on the number of voltage levels. Furthermore, the DCL signal can be a two-bit or higher signal. Additionally, the digital control signal can be one or more DCL signals, and it can also be a source-synchronous control signal.

[0172] Switch S51 is connected between input terminal 131 and output terminal 130. Specifically, switch S51 has a first terminal connected to input terminal 131 and a second terminal connected to output terminal 130. In the above connection structure, switch S51 switches the connection between input terminal 131 and output terminal 130 by switching on / off.

[0173] Switch S52 is connected between input terminal 132 and output terminal 130. Specifically, switch S52 has a first terminal connected to input terminal 132 and a second terminal connected to output terminal 130. In the above connection structure, switch S52 switches the connection between input terminal 132 and output terminal 130 by switching on / off.

[0174] Switch S53 is connected between input terminal 133 and output terminal 130. Specifically, switch S53 has a first terminal connected to input terminal 133 and a second terminal connected to output terminal 130. In the above connection structure, switch S53 switches the connection between input terminal 133 and output terminal 130 by switching on / off.

[0175] Switch S54 is connected between input terminal 134 and output terminal 130. Specifically, switch S54 has a first terminal connected to input terminal 134 and a second terminal connected to output terminal 130. In the above connection structure, switch S54 switches the connection between input terminal 134 and output terminal 130 by switching on / off.

[0176] Multiple switches S51 to S54 are controlled to be exclusively turned on. That is, only one of switches S51 to S54 is turned on, while the remaining switches S51 to S54 are turned off. As a result, the output switch circuit 30 can output a voltage selected from voltages V11 to V14.

[0177] The output switch circuit 30, having the structure described above, receives a digital control signal corresponding to the envelope signal from the control terminal 135. Based on the digital control signal input from the control terminal 135, it controls the opening and closing of multiple switches S51 to S54, selecting at least one of the multiple voltages V11 to V14 generated by the switched capacitor circuit 20. The output switch circuit 30 outputs the selected voltage.

[0178] also, Figure 6 The structure of the output switch circuit 30 shown is an example, and the structure of the output switch circuit 30 is not limited to... Figure 6 The structure shown is as follows. Specifically, switches S51 to S54 can have any structure as long as they can select any one of the four input terminals 131 to 134 and connect that input terminal to the output terminal 130. For example, the output switch circuit 30 may also include a switch connected between switches S51 to S53, switch S54, and the output terminal 130. Alternatively, for example, the output switch circuit 30 may also include a switch connected between switches S51 and S52, switches S53 and S54, and the output terminal 130.

[0179] Alternatively, for example, in the case of selecting a voltage from two discrete voltage levels, the output switching circuit 30 may have at least switches S52 and S53.

[0180] Alternatively, the output switch circuit 30 can also be configured to output two or more voltages. In the above case, the output switch circuit 30 may further include an additional switch group and additional output terminals, which are the same number as the groups of switches S51 to S54.

[0181] The switch included in the output switching circuit 30 is contained in the tracker component 3 (see reference). Figure 3 Specifically, the tracker component 3 includes multiple switches S51 to S54.

[0191] Switch S71 is connected between input terminal 110 and one end (first terminal) of power inductor L71. Specifically, switch S71 has a first terminal connected to input terminal 110 and a second terminal connected to one end of power inductor L71 via inductor connection terminal 115. In the above connection structure, switch S71 switches between connection and non-connection between input terminal 110 and one end of power inductor L71 by switching on / off.

[0192] Switch S72 is connected between one end (first end) of power inductor L71 and ground. Specifically, switch S72 has a first terminal connected to one end of power inductor L71 via inductor connection terminal 115 and a second terminal connected to ground. In the above connection structure, switch S72 switches the connection between one end of power inductor L71 and ground, and the non-connection, by switching on / off.

[0193] Switch S61 is connected between the other end (second end) of power inductor L71 and output terminal 111. Specifically, switch S61 has a first terminal connected to the other end of power inductor L71 and a second terminal connected to output terminal 111.

[0202] The switch included in the tuner circuit 10 is mounted on the tracker component 3 (see reference). Figure 3 Specifically, the tracker component 3 includes multiple switches S61 to S63, S71, and S72.

[0203] (6) Tracker module operation

[0204] Next, refer to Figure 3 The operation of the tracker module 1 according to Embodiment 1 will be described. The communication frequency band corresponding to the first power amplifier 81A to which the power supply voltage V1 is applied from the tracker component 3 is designated as the first communication frequency band, and the communication frequency band corresponding to the first power amplifier 81B to which the power supply voltage V1 is applied from the tracker component 3 is designated as the second communication frequency band.

[0205] The tracker module 1 according to Embodiment 1 is capable of simultaneous communication based on two first power amplifiers 81. For example, the tracker module 1 is capable of simultaneous communication based on first power amplifiers 81A and 81B. In this case, the tracker component 3 has the function of outputting a power supply voltage V1 from the first output terminals 6A and 6B.

[0206] Tracker component 3 outputs power supply voltage V1. Tracker module 1 outputs power supply voltage V1 from first output terminal 6. Power supply voltage V1 is applied to first power amplifiers 81A to 81D. Since power supply voltage V1 does not pass through a filter (not shown), a relatively large power supply voltage V1 is output from first output terminal 6 of tracker module 1.

[0207] Here, the method for confirming whether the multiple first power amplifiers 81 are used for simultaneous communication is explained. First, the operation of simultaneous communication is confirmed in the communication device 9 (high-frequency module 8). Next, after confirming the operation of simultaneous communication, the simultaneous operation of the multiple first power amplifiers 81 is confirmed. Then, it is confirmed that all the multiple first power amplifiers 81 operating simultaneously are connected to tracker module 1, and not connected to other tracker modules (power supplies). In this case, since the multiple first power amplifiers 81 operating simultaneously are supplied with power supply voltage V1 from only one tracker module 1, it can be said that they are used for simultaneous communication.

[0208] (7) Effect

[0209] In the tracker module 1 according to Embodiment 1, three or more first output terminals 6 are arranged on the outermost periphery of the second main surface 22 of the substrate 2. This facilitates routing from each first output terminal 6 into the substrate (mother substrate, etc.) on which the tracker module 1 is mounted. In other words, the wiring length between the first output terminal 6 and the first power amplifier 81 can be shortened. Furthermore, the wiring layout between the first output terminal 6 and the first power amplifier 81 can be simplified.

[0210] In the tracker module 1 according to Embodiment 1, three or more first output terminals 6 are arranged on the second main surface 22 of the substrate 2 without being adjacent to each other. As a result, the isolation between the first output terminals 6 can be improved.

[0211] In the tracker module 1 according to Embodiment 1, at least two first output terminals 6 are arranged along two different edges of the substrate 2. This allows for easy layout of the first output terminals 6 over a large area.

[0212] In the tracker module 1 according to Embodiment 1, the two edges of the substrate 2 are opposite to each other, and at least two first output terminals 6 are arranged along the two opposite edges. As a result, the isolation between the first output terminals 6 can be improved.

[0213] In the tracker module 1 according to Embodiment 1, when viewed from the thickness direction of the substrate 2, the first output terminal 6 (in) Figure 1In the example, the first output terminals 6A and 6D overlap with the tracker component 3. This shortens the wiring length between the tracker component 3 and the first output terminal 6.

[0214] (8) Variations

[0215] Hereinafter, a variation of Implementation 1 will be described.

[0216] (8.1) Variation Example 1

[0217] As a variation of embodiment 1, it is not limited to all of the plurality of first output terminals 6 being disposed on the outermost periphery of the second main surface 22 of the substrate 2. In other words, at least one of the plurality of first output terminals 6 may be disposed at a position where there are other external connection terminals 5 between the first output terminals 6 and the outer edge of the substrate 2. In short, it is sufficient for three or more first output terminals 6 to be disposed on the outermost periphery of the second main surface 22 of the substrate 2.

[0218] (8.2) Variation Example 2

[0219] As a variation of embodiment 1, Example 2 is not limited to the plurality of first output terminals 6 being arranged on the second main surface 22 of the substrate 2 without being adjacent to each other. Alternatively, two or more of the plurality of first output terminals 6 may be arranged adjacent to each other.

[0220] (8.3) Variation Example 3

[0221] As a variation of embodiment 1, Example 3 is not limited to the arrangement of multiple first output terminals 6 along two different edges of the substrate 2. Multiple first output terminals 6 may also be arranged along the same edge of the substrate 2.

[0222] (8.4) Variation Example 4

[0223] As a variation of embodiment 1, Example 4 is not limited to the plurality of first output terminals 6 overlapping with the tracker component 3 when viewed from the thickness direction of the substrate 2. That is, the first output terminals 6 may also be arranged on the second main surface 22 of the substrate 2 at a position that does not overlap with the tracker component 3.

[0224] (8.5) Variation Example 5

[0225] As a variation of embodiment 1, in embodiment 5, all of the multiple first output terminals 6 may overlap with the tracker component 3 when viewed from the thickness direction of the substrate 2.

[0226] Therefore, in all of the plurality of first output terminals 6, the first output terminal 6 can be connected to the tracker component 3 within the configuration area of ​​the tracker component 3. As a result, in all of the plurality of first output terminals 6, the wiring length between the first output terminal 6 and the tracker component 3 can be shortened.

[0227] In the tracker modules involved in the above-described variations, they achieve the same effect as tracker module 1 involved in embodiment 1.

[0228] (Implementation Method 2)

[0229] like Figure 7 as well as Figure 8 As shown, the tracker module 1a according to Embodiment 2 differs from the tracker module 1 according to Embodiment 1 (refer to...) in that it has a second output terminal 7. Figure 1 (Different). Furthermore, regarding the tracker module 1a according to Embodiment 2, the same reference numerals are used for the same constituent elements as those in the tracker module 1 according to Embodiment 1, and descriptions are omitted.

[0230] (1) Structure

[0231] like Figure 8 As shown, the tracker module 1a according to Embodiment 2 is configured to output a power supply voltage V1 to a plurality of (five in the example) first power amplifiers 81. Additionally, the tracker module 1a is configured to output a power supply voltage V2 to a second power amplifier 82. The second power amplifier 82 is configured to amplify a second transmitted signal (high-frequency signal) when a power supply voltage V2 is applied to an amplifying element (not shown). The plurality of first power amplifiers 81 and the second power amplifier 82 amplify transmitted signals in different communication frequency bands.

[0232] Tracker module 1a is the same as tracker module 1 according to embodiment 1, and is used in communication device 9 (see reference 9). Figure 4 More specifically, tracker module 1a and high-frequency module 8 (see reference) Figure 4 The multiple first power amplifiers 81 and second power amplifiers 82 contained in the communication device 9 are used together.

[0233] like Figure 7 as well as Figure 8 As shown, the tracker module 1a according to Embodiment 2 includes a substrate 2, a tracker component 3a, and a plurality of (40 in the example) external connection terminals 5.

[0234] Here, the ET mode is used when the first power amplifier 81 and the second power amplifier 82 amplify the transmitted signal using the power supply voltages V1 and V2 from the tracker module 1a.

[0235] In the implementation method 2, where the analog ET method is used, the tracker module 1a continuously detects the envelope of the amplitude of the first transmitted signal input to each of the multiple first power amplifiers 81, and outputs a power supply voltage V1, whose amplitude level changes continuously according to the continuously detected envelope, to the first power amplifier 81. Additionally, the tracker module 1a continuously detects the envelope of the amplitude of the second transmitted signal input to the second power amplifier 82, and outputs a power supply voltage V2, whose amplitude level changes continuously according to the continuously detected envelope, to the second power amplifier 82.

[0236] In the implementation method 2 using the digital ET method, the tracker module 1a discretely detects the envelope of the amplitude of the first transmitted signal input to each of the multiple first power amplifiers 81, and outputs a power supply voltage V1, whose amplitude level varies discretely according to the discretely detected envelope, to the first power amplifier 81. Additionally, the tracker module 1a discretely detects the envelope of the amplitude of the second transmitted signal input to the second power amplifier 82, and outputs a power supply voltage V2, whose amplitude level varies discretely according to the discretely detected envelope, to the second power amplifier 82.

[0237] Tracker module 1a, like tracker module 1 in embodiment 1, includes a pre-tuning circuit 10 (see reference 10). Figure 6 ), switched capacitor circuit 20 (refer to) Figure 6 ), Output switch circuit 30 (refer to) Figure 6 ), and DC power supply 50 (refer to) Figure 5 ).

[0238] (1.1) Tracker components

[0239] like Figure 7 as well as Figure 8 As shown, the tracker component 3a is disposed on the first main surface 21 of the substrate 2, similar to the tracker component 3 in Embodiment 1 (see reference). Figure 2 Tracker component 3a generates power supply voltages V1 and V2.

[0240] The tracker component 3a is configured to output a power supply voltage V1 to multiple (five in the example shown) first power amplifiers 81. For example, the tracker component 3a can independently output the power supply voltage V1 to each of the multiple first power amplifiers 81. More specifically, the tracker component 3a generates a power supply voltage V1 with an amplitude level corresponding to the envelope of the amplitude of the first transmitted signal, and outputs the generated power supply voltage V1 to the first power amplifiers 81. Additionally, the tracker component 3a is configured to output a power supply voltage V2 to a second power amplifier 82. More specifically, the tracker component 3a generates a power supply voltage V2 with an amplitude level corresponding to the envelope of the amplitude of the second transmitted signal, and outputs the generated power supply voltage V2 to the second power amplifier 82.

[0241] Tracker component 3a outputs power voltage V1 to first power amplifier 81 via first output terminal 6 via ET mode. Additionally, tracker component 3a outputs power voltage V2 to second power amplifier 82 via second output terminal 7 via ET mode.

[0242] (1.2) External connection terminals

[0243] like Figure 7 As shown, the plurality of external connection terminals 5 include input terminals 51, a plurality of (four in the example) control terminals 52, a plurality of (two in the example) signal terminals 53, a plurality of (five in the example) first output terminals 6, and a second output terminal 7. The plurality of external connection terminals 5 are arranged in a grid pattern, for example, on the second main surface 22 of the substrate 2. Figure 7 In the example, multiple external connection terminals 5 are configured as a 5×8 grid.

[0244] (1.3) First output terminal

[0245] like Figure 7 as well as Figure 8 As shown, the plurality of first output terminals 6 are terminals for outputting a power supply voltage V1 from the tracker module 1a to the plurality of first power amplifiers 81. More specifically, the plurality of first output terminals 6 correspond one-to-one with the plurality of first power amplifiers 81, and each first output terminal 6 is a terminal for outputting the power supply voltage V1 output from the tracker component 3a to the corresponding first power amplifier 81. The power supply voltage V1 output from the tracker component 3a is transmitted through each first output terminal 6.

[0246] exist Figure 8In the example, the first output terminal 6A is used to output the power supply voltage V1 to the first power amplifier 81A. The first output terminal 6B is used to output the power supply voltage V1 to the first power amplifier 81B. The first output terminal 6C is used to output the power supply voltage V1 to the first power amplifier 81C. The first output terminal 6D is used to output the power supply voltage V1 to the first power amplifier 81D. The first output terminal 6E is used to output the power supply voltage V1 to the first power amplifier 81E.

[0247] like Figure 7 As shown, when viewed from the thickness direction of the substrate 2, the first output terminals 6A, 6D, and 6E of the plurality of first output terminals 6 overlap with the tracker component 3a.

[0248] This allows the output terminals (not shown) of tracker component 3a to be connected to the first output terminals 6A, 6D, and 6E within the configuration area of ​​tracker component 3a. As a result, the wiring lengths between the first output terminals 6A, 6D, and 6E of the first power amplifier 81 and tracker component 3a can be shortened. More specifically, the wiring lengths between the first output terminal 6A of the first power amplifier 81A and tracker component 3a, the first output terminal 6D of the first power amplifier 81D and tracker component 3a, and the first output terminal 6E of the first power amplifier 81E and tracker component 3a can be shortened.

[0249] However, in Embodiment 2, similar to Embodiment 1, a plurality of first output terminals 6 are disposed on the outermost periphery of the second main surface 22 of the substrate 2. That is, in the state where a plurality of external connection terminals 5 are disposed, the first output terminals 6 are disposed at the ends.

[0250] Therefore, it is easy to connect the first output terminal 6 to the first power amplifier 81. More specifically, on the substrate (mother substrate) for mounting the tracker module 1a, by configuring the tracker module 1a so that the first output terminal 6 is close to the first power amplifier 81, the wiring length between the first output terminal 6 and the first power amplifier 81 can be shortened. As a result, compared to the case where the first output terminal 6 is not disposed on the outermost periphery of the second main surface 22 of the substrate 2, it is easier to form a wiring pattern portion for connecting the first output terminal 6 to the first power amplifier 81.

[0251] like Figure 7As shown, a plurality of first output terminals 6 are arranged on the second main surface 22 of the substrate 2 without being adjacent to each other. More specifically, on the second main surface 22 of the substrate 2, first output terminals 6A, 6B, 6C, 6D, and 6E are arranged on the second main surface 22 without being adjacent to each other. Furthermore, it is preferable that the external connection terminals 5 present between the first output terminals 6 are grounded terminals connected to ground.

[0252] Therefore, since the distance between the multiple first output terminals 6 can be increased, the isolation between the multiple first output terminals 6 can be improved compared to the case where they are adjacent to each other.

[0253] exist Figure 7 In the example, since there are two external connection terminals 5 between the first output terminal 6A and the first output terminal 6E, it can be said that the first output terminals 6A and 6E are not adjacent to each other. Similarly, since there is one external connection terminal 5 between the first output terminals 6B and 6C, it can be said that the first output terminals 6B and 6C are not adjacent to each other. Furthermore, since there is one external connection terminal 5 between the first output terminals 6E and 6B, it can be said that the first output terminals 6E and 6B are not adjacent to each other.

[0254] (1.4) Second output terminal

[0255] Figure 7 The second output terminal 7 shown is different from the first output terminal 6; it is used to output the power supply voltage V2 from the tracker module 1a to the second power amplifier 82. More specifically, the second output terminal 7 is used to output the power supply voltage V2 from the tracker component 3a to the second power amplifier 82. The power supply voltage V2 output from the tracker component 3a is transmitted through the second output terminal 7.

[0256] like Figure 7 As shown, the second output terminal 7 is disposed on the second main surface 22 of the substrate 2. Figure 8 As shown, the second output terminal 7 is connected to the second power amplifier 82. The second output terminal 7 is connected to the tracker component 3a. Here, "the second output terminal 7 is connected to the tracker component 3a" includes both the second output terminal 7 being connected to the tracker component 3a without passing through other components and the second output terminal 7 being connected to the tracker component 3a via other components. That is, "the second output terminal 7 is connected to the tracker component 3a" includes both the second output terminal 7 being directly connected to the tracker component 3a and the second output terminal 7 being indirectly connected to the tracker component 3a.

[0257] The second output terminal 7 is connected to the second power amplifier 82 among multiple power amplifiers, and is disposed on the second main surface 22 of the substrate 2 at a position different from the outermost periphery.

[0258] In addition, the second output terminal 7 overlaps with the tracker component 3a when viewed from the thickness direction of the substrate 2.

[0259] Therefore, the output terminal (not shown) of tracker component 3a and the second output terminal 7 can be connected within the configuration area of ​​tracker component 3a. As a result, the wiring length between the second output terminal 7 connected to the second power amplifier 82 and tracker component 3a can be shortened compared to the case where the second output terminal connected to the second power amplifier 82 does not overlap with the tracker component.

[0260] However, the maximum load current flowing through the second output terminal 7 is greater than the maximum load current flowing through each of the plurality of first output terminals 6. Therefore, a larger power supply can be output to the second power amplifier 82 via the second output terminal 7.

[0261] Furthermore, the power level of the second power amplifier 82 connected to the second output terminal 7 is greater than the power level of each of the multiple first power amplifiers 81 connected to the multiple first output terminals 6. For example, the first power amplifiers 81 are power amplifiers corresponding to a lower power level, while the second power amplifier 82 is a power amplifier corresponding to a higher power level. As a result, a larger power supply can be output to the second power amplifier 82, which has a higher power level.

[0262] Here, "power class" refers to the classification of a terminal's output power based on definitions such as maximum output power. A smaller value indicates a higher power output. For example, power class 2 corresponds to a higher power output than power class 3. The maximum output power of a higher power class is greater than that of a lower power class. For instance, maximum output power is measured using methods defined by 3GPP (3rd Generation Partnership Project).

[0263] (2) High-frequency module

[0264] Figure 8 The second power amplifier 82 shown includes a transistor (amplifying element). The transistor in the second power amplifier 82 is, for example, an NPN transistor, which is an amplifying element that amplifies high-frequency signals when a power supply voltage V2 is applied. The transistor amplifies the high-frequency signal output from the RF signal processing circuit 94. The collector of the transistor is electrically connected to the second output terminal 7 of the tracker module 1a. The emitter of the transistor is at ground potential.

[0265] A power supply voltage V2 is applied to the transistor of the second power amplifier 82. A high-frequency signal output from the RF signal processing circuit 94 is input to the base of the transistor. A tracker module 1a is connected to the collector of the transistor. A power supply voltage V2 controlled according to the amplitude level of the high-frequency signal is applied from the tracker module 1a to the collector of the transistor. In addition, the collector of the transistor is connected to a second transmit filter (not shown).

[0266] (3) Actions of the tracker module

[0267] Next, refer to Figure 8 The operation of the tracker module 1a according to Embodiment 2 will be described. The communication frequency band corresponding to the first power amplifier 81 to which the power supply voltage V1 is applied from the tracker component 3a is designated as the first communication frequency band, and the communication frequency band corresponding to the second power amplifier 82 to which the power supply voltage V2 is applied from the tracker component 3a is designated as the second communication frequency band.

[0268] Tracker component 3a outputs power supply voltage V1. Tracker module 1a outputs power supply voltage V1 from first output terminal 6. Power supply voltage V1 is applied to first power amplifiers 81A to 81E. Additionally, tracker component 3a outputs power supply voltage V2. Tracker module 1a outputs power supply voltage V2 from second output terminal 7. Power supply voltage V2 is applied to second power amplifier 82.

[0269] (4) Effect

[0270] In the tracker module 1a according to embodiment 2, the maximum load current flowing through the second output terminal 7 is greater than the maximum load current flowing through the first output terminal 6. As a result, a larger power supply can be output to the second power amplifier 82 via the second output terminal 7.

[0271] In the tracker module 1a according to Embodiment 2, the power level of the second power amplifier 82 connected to the second output terminal 7 is greater than the power level of the first power amplifier 81 connected to the first output terminal 6. Therefore, a larger power output can be provided to the second power amplifier 82, which has a larger power level.

[0272] In the tracker module 1a according to Embodiment 2, the second output terminal 7 overlaps with the tracker component 3a. This shortens the wiring length between the tracker component 3a and the second output terminal 7.

[0273] (5) Variations

[0274] Hereinafter, a variation of embodiment 2 will be described.

[0275] (5.1) Variation Example 1

[0276] As a variation of embodiment 2, the second output terminal 7 is not limited to overlapping the tracker component 3a when viewed from the thickness direction of the substrate 2. That is, the second output terminal 7 may also be disposed on the second main surface 22 of the substrate 2 at a position that does not overlap with the tracker component 3a.

[0277] (5.2) Variation Example 2

[0278] As a variation of embodiment 2, the plurality of external connection terminals 5 may also include a plurality of second output terminals 7. In the case of variation 2, when viewed from the thickness direction of the substrate 2, all of the plurality of second output terminals 7 may overlap with the tracker component 3a, or only a portion of the plurality of second output terminals 7 may overlap with the tracker component 3a when viewed from the thickness direction of the substrate 2. When there are two second output terminals 7, one of the two second output terminals 7 may overlap with the tracker component 3a, while the other (remaining) of the two second output terminals 7 may not overlap with the tracker component 3a. In short, when viewed from the thickness direction of the substrate 2, at least one of the plurality of second output terminals 7 may overlap with the tracker component 3a. Alternatively, when viewed from the thickness direction of the substrate 2, none of the plurality of second output terminals 7 may overlap with the tracker component 3a.

[0279] In the tracker modules involved in the above-described variations, the same effect is achieved as that of the tracker module 1a involved in Embodiment 2.

[0280] (Implementation Method 3)

[0281] The tracker module 1b according to embodiment 3 is similar to the tracker module 1a according to embodiment 2 (see also embodiment 2) in that it is capable of simultaneous communication based on three first power amplifiers 81. Figure 7 (Different). Furthermore, regarding the tracker module 1b according to Embodiment 3, the same reference numerals are used for the same constituent elements as those in the tracker module 1a according to Embodiment 2, and descriptions are omitted.

[0282] (1) Structure

[0283] like Figure 9 As shown, the tracker module 1b of Embodiment 3 is the same as the tracker module 1a of Embodiment 2, including a substrate 2, a tracker component 3b, and a plurality of (48 in the example) external connection terminals 5.

[0284] like Figure 9 As shown, the multiple external connection terminals 5 include input terminals 51, multiple (4 in the example) control terminals 52, multiple (3 in the example) signal terminals 53, multiple (6 in the example) first output terminals 6, and second output terminals 7.

[0285] like Figure 9 as well as Figure 10 As shown, the tracker module 1b according to Embodiment 3 is capable of simultaneous communication based on three first power amplifiers 81. For example, the tracker module 1b is capable of simultaneous communication based on first power amplifiers 81D, 81E, and 81F. In this case, the tracker component 3b has the function of outputting a power supply voltage V1 from the first output terminals 6D, 6E, and 6F.

[0286] In embodiment 3, three sets of signal terminals 53 are provided in order to enable simultaneous communication based on the three first power amplifiers 81 as described above.

[0287] like Figure 9 As shown, the second output terminal 7 overlaps with the tracker component 3b when viewed from the thickness direction of the substrate 2.

[0288] This allows the output terminal (not shown) of tracker component 3b to be connected to the second output terminal 7 within the configuration area of ​​tracker component 3b. As a result, the wiring length between the second output terminal 7 connected to the second power amplifier 82 and tracker component 3b can be further shortened.

[0289] Tracker module 1b, like tracker module 1a in embodiment 2, includes a pre-tuning circuit 10 (see reference 10). Figure 6 ), switched capacitor circuit 20 (refer to) Figure 6 ), Output switch circuit 30 (refer to) Figure 6 ), and DC power supply 50 (refer to) Figure 5 ).

[0290] (2) Effect

[0291] In the tracker module 1b according to Embodiment 3, similarly to the tracker module 1a according to Embodiment 2, the second output terminal 7 overlaps with the tracker component 3b. This allows for a reduction in the wiring length between the tracker component 3b and the second output terminal 7.

[0292] In the tracker module 1b according to Embodiment 3, similar to the tracker module 1a according to Embodiment 2, the maximum load current flowing through the second output terminal 7 is greater than the maximum load current flowing through the first output terminal 6. Therefore, a larger power supply can be output to the second power amplifier 82 via the second output terminal 7.

[0293] (Implementation Method 4)

[0294] like Figure 11As shown, the tracker module 1c according to embodiment 4 is connected to the first power amplifier 81 via filters 4 at the point where the plurality of first output terminals 6 are respectively connected to the first power amplifier 81, which is different from the tracker module 1 according to embodiment 1 (refer to...). Figure 3 (Different). Furthermore, regarding the tracker module 1c according to Embodiment 4, the same reference numerals are used for the same constituent elements as those in the tracker module 1 according to Embodiment 1, and descriptions are omitted.

[0295] (1) Structure

[0296] like Figure 11 As shown, the tracker module 1c according to Embodiment 4 is connected to a plurality of filters 4. Similar to the tracker module 1 according to Embodiment 1, the tracker module 1c includes a substrate 2 (see reference 1). Figure 1 ), tracker component 3, and multiple external connection terminals 5 (see reference) Figure 1 Multiple filters 4 are connected to the tracker module 1c.

[0297] Each of the multiple first output terminals 6 corresponds one-to-one with a multiple filter 4. Each first output terminal 6 is connected to the corresponding first power amplifier 81 via the corresponding filter 4.

[0298] (2) Filter

[0299] like Figure 11 As shown, multiple filters 4 are connected to tracker module 1c. Each filter 4 is connected to tracker component 3 via first output terminal 6. Each filter 4 reduces the high-order harmonic components of power supply voltage V1. Thus, noise originating from power supply voltage V1 can be reduced.

[0300] Each filter 4 is, for example, an LC filter that includes inductors and capacitors as its main components. Each filter is, for example, a low-pass filter. The inductor is, for example, a surface-mount inductor, and the capacitor is, for example, a surface-mount capacitor.

[0301] Each filter 4 is, for example, an L-shaped filter. As a first example, filter 4 is formed by placing an inductor in the path between the tracker component 3 and the first output terminal 6, and connecting one end of a capacitor in the path between the inductor and the first output terminal 6. As a second example, filter 4 is formed by placing an inductor in the path between the tracker component 3 and the first output terminal 6, and connecting one end of a capacitor in the path between the inductor and the tracker component 3.

[0302] Filter 4 allows the power supply voltage V1 from tracker component 3 to pass through. Since the power supply voltage V1 is not a sinusoidal voltage, filter 4 reduces the higher harmonic components of the power supply voltage V1. That is, filter 4 cuts off the higher harmonic components of the power supply voltage V1, allowing the fundamental component of the power supply voltage V1 to pass through. Then, the power supply voltage V1 that has passed through filter 4 is applied to the first power amplifier 81. Thus, a power supply voltage V1 with reduced higher harmonic components is output from filter 4.

[0303] (3) Details of the tracker module

[0304] Next, refer to Figure 12 as well as Figure 13 The details of the tracker module 1c involved in Embodiment 4 will be described.

[0305] like Figure 12 as well as Figure 13 As shown, the tracker module 1c includes a pre-tuner circuit 10, a switched capacitor circuit 20, an output switch circuit 30, a filter 4, and a DC power supply 50.

[0306] In embodiment 4, the output switching circuit 30 selects at least one of a plurality of voltages generated by the switched capacitor circuit 20 and outputs it to the filter 4 based on a digital control signal corresponding to the envelope signal.

[0307] Filter 4 filters the signal (voltage) output from the output switching circuit 30. Filter 4 may include, for example, a low-pass filter (LPF).

[0308] Furthermore, the tracker module 1c may not include at least one of the pre-tuning circuit 10 and the DC power supply 50. For example, the tracker module 1c may not include the DC power supply 50. Additionally, any combination of the pre-tuning circuit 10, the switched capacitor circuit 20, the output switching circuit 30, and the filter 4 can be integrated into a single circuit. Figure 13 The detailed circuit structure example of tracker module 1c will be described later.

[0309] (3.1) Circuit structure of the tracker module

[0310] Next, refer to Figure 13 The circuit structure of the pre-tuner circuit 10, switched capacitor circuit 20, output switch circuit 30 and filter 4 included in the tracker module 1c is described.

[0311] also, Figure 13The circuit structures provided are illustrative. The pre-tuner circuit 10, switched capacitor circuit 20, output switch circuit 30, and filter 4 can be installed using a variety of circuit configurations and any of the circuit techniques employed. Therefore, the descriptions of the circuits provided below should not be interpreted in a restrictive manner.

[0312] (3.2) Switched capacitor circuit

[0313] like Figure 13 As shown, the switched capacitor circuit 20 of Embodiment 4 and the switched capacitor circuit 20 of Embodiment 1 (refer to...) Figure 6 Similarly, it includes multiple (six in the example) capacitors C11 to C16, multiple (four in the example) capacitors C21 to C24, multiple (sixteen in the example) switches S11 to S14, S21 to S24, S31 to S34, S41 to S44, and control terminal 120. Furthermore, the switched capacitor circuit 20 of Embodiment 4 has the same structure and function as the switched capacitor circuit 20 of Embodiment 1; therefore, the same reference numerals are used and descriptions are omitted.

[0314] (3.3) Output Switching Circuit

[0315] like Figure 13 As shown, the output switch circuit 30 of Embodiment 4 and the output switch circuit 30 of Embodiment 1 (see reference) Figure 6 Similarly, it includes multiple (four in the example) input terminals 131-134, multiple (four in the example) switches S51-S54, output terminal 130, and control terminal 135. Furthermore, the output switch circuit 30 of Embodiment 4 has the same structure and function as the output switch circuit 30 of Embodiment 1; therefore, the same reference numerals are used and descriptions are omitted.

[0316] (3.4) Presetter Circuit

[0317] like Figure 13 As shown, the preset circuit 10 is the same as the preset circuit 10 of Embodiment 1 (refer to...). Figure 6 Similarly, it includes an input terminal 110, multiple (four in the example) output terminals 111-114, multiple inductor connection terminals 115 and 116, a control terminal 117, multiple (five in the example) switches S61, S62, S63, S71, and S72, a power inductor L71, and multiple capacitors C61, C62, C63, and C64. Furthermore, the preset circuit 10 of Embodiment 4 has the same structure and function as the preset circuit 10 of Embodiment 1; therefore, the same reference numerals are used and descriptions are omitted.

[0318] (3.5) Filter

[0319] Next, the circuit structure of filter 4 will be explained. Figure 13 As shown, filter 4 includes multiple (3 in the example) inductors L51 to L53, multiple (2 in the example) capacitors C51 and C52, resistor R51, input terminal 140, and output terminal 141.

[0320] Input terminal 140 is a voltage input terminal selected by output switching circuit 30. That is, input terminal 140 is a terminal for accepting a voltage selected from multiple voltages V11 to V14.

[0321] Output terminal 141 is the output terminal for power supply voltage V1. That is, output terminal 141 is the terminal used to supply power supply voltage V1 to the first power amplifier 81.

[0322] Inductors L51 and L52 are connected in series between input terminal 140 and output terminal 141. The series connection of inductor L53 and resistor R51 is connected in parallel with inductor L51. Capacitor C51 is connected between the junction of inductors L51 and L52 and ground. Capacitor C52 is connected between output terminal 141 and ground.

[0323] In the above structure, filter 4 is an LC low-pass filter with inductors L51 to L53 arranged in the series arm path and capacitors C51 and C52 arranged in the parallel arm path. Therefore, filter 4 can reduce high-frequency components contained in the power supply voltage. For example, if the specified frequency band is used for frequency division duplex (FDD), filter 4 is configured to reduce components of the downlink operating frequency band of the specified frequency band.

[0324] also, Figure 13 The structure of filter 4 shown is an example; filter 4 is not limited to... Figure 13 The structure shown. Filter 4 can also be configured as a bandpass filter or a high-pass filter depending on the frequency bands that should be removed.

[0325] Alternatively, filter 4 may have two or more LC filters. These two or more LC filters are connected together to output terminal 130, and each LC filter has a passband or attenuation band corresponding to a different frequency band. Alternatively, a first filter group consisting of two or more LC filters may be connected to the first output terminal of output switching circuit 30, and a second filter group consisting of two or more other LC filters may be connected to the second output terminal of output switching circuit 30, with each LC filter having a passband or attenuation band corresponding to a different frequency band. In the above cases, filter 4 may also have two or more output terminals, simultaneously outputting two or more power supply voltages V1 to different first power amplifiers 81.

[0326] (4) Effect

[0327] In the tracker module 1c according to embodiment 4, three or more first output terminals 6 are respectively connected to corresponding first power amplifiers 81 via filters 4. As a result, the noise component of the power supply voltage V1 supplied to the first power amplifier 81 can be reduced.

[0328] (5) Variations

[0329] Hereinafter, a variation of embodiment 4 will be described.

[0330] (5.1) Variation Example 1

[0331] As a variation of implementation method 4, each of the plurality of filters 4 may not be an L-type filter, but rather another type of LC filter. Each filter 4 may be, for example, a π-type filter or a T-type filter.

[0332] When filter 4 is a π-type filter, an inductor is placed in the path between the first output terminal 6 and the first power amplifier 81, one end of the first capacitor is connected in the path between the first output terminal 6 and the inductor, and one end of the second capacitor is connected in the path between the inductor and the first power amplifier 81, thereby forming filter 4.

[0333] When filter 4 is a T-type filter, the first inductor and the second inductor are connected in series in the path between the first output terminal 6 and the first power amplifier 81, and one end of a capacitor is connected in the path between the first inductor and the second inductor, thereby forming filter 4. Alternatively, one end of a series circuit of a capacitor and a third inductor can be connected in the path between the first inductor and the second inductor.

[0334] (5.2) Variation Example 2

[0335] As a variation of embodiment 4, in a second embodiment, multiple filters 4 may be components in which the inductor and capacitor constituting the filter 4 are packaged (in a single package). This reduces the configuration area of ​​each filter 4.

[0336] In variation 2 of embodiment 4, it is not limited to using a single-packaged filter for all of the plurality of filters 4; a single-packaged filter may also be used for at least one of the plurality of filters 4. More specifically, a single-packaged filter may be used for at least one of the plurality of filters 4, while unpackaged filters may be used for the remaining filters of the plurality of filters 4.

[0337] (5.3) Variation Example 3

[0338] As a variation of embodiment 4, filter 4 can be any filter that cuts off the higher harmonic components of the power supply voltage V1, and is not limited to a low-pass filter.

[0339] (5.4) Variation Example 4

[0340] As a variation of embodiment 4, the tracker module 1c may also include a second output terminal 7, similar to embodiments 2 and 3. The second output terminal 7 may be connected to the second power amplifier 82 via a filter, or it may be connected to the second power amplifier 82 without a filter.

[0341] When the second output terminal 7 is connected to the second power amplifier 82 without passing through a filter, the power supply voltage V2 from the tracker module 1c can be output to the second power amplifier 82 without attenuation in the filter.

[0342] However, in Modification 4, the power level of the second power amplifier 82 connected to the second output terminal 7 may be greater than the power level of each of the multiple first power amplifiers 81 connected to the multiple first output terminals 6. For example, the first power amplifier 81 is a power amplifier corresponding to a non-high power level, and the second power amplifier 82 is a power amplifier corresponding to a high power level.

[0343] As described above, since the power supply voltage V2 output from the second output terminal 7 does not pass through the filter 4, it can be output to the second power amplifier 82 without being affected by the losses caused by the filter 4. Therefore, a larger power supply can be output to the second power amplifier 82, which has a higher power rating.

[0344] In addition, in the case of Modification 4, the multiple first power amplifiers 81 connected to the multiple first output terminals 6 may be power amplifiers that amplify FDD-based transmission signals, and the second power amplifier connected to the second output terminal 7 may be power amplifiers that amplify TDD-based transmission signals.

[0345] In FDD-based communication, the receiving operation occurs simultaneously with the transmitting operation. Since the power supply voltage V1 is not a sine wave, it contains high-order harmonic components. These high-order harmonic components of the power supply voltage V1 can become noise components during the receiving operation. For example, the mixing of these high-order harmonic components with the transmitted signal can generate noise components at frequencies within the communication band of the received signal.

[0346] In Modification 4, the power supply voltage V1 is output from the tracker component 3 and then through the filter 4 to the first power amplifier 81. Therefore, in FDD-based communication, the noise component of the power supply voltage V1 can be reduced.

[0347] On the other hand, in the case of TDD-based communication, a higher power supply voltage is required compared to FDD-based communication. The power supply voltage V2 of the second power amplifier 82 needs to be higher than the power supply voltage V1 of the first power amplifier 81. The power supply voltage V2 is output to the second power amplifier 82 without passing through the filter 4. Since there is no attenuation in the filter 4, the desired voltage value of the power supply voltage V2 can be applied losslessly in TDD-based communication. On the other hand, in FDD-based communication, the noise component of the power supply voltage V1 can be reduced.

[0348] (5.5) Variation Example 5

[0349] As a variation of implementation 4, filter 4 can also be an IPD (Integrated Passive Device) that includes an inductor and a capacitor.

[0350] In the tracker modules involved in the above-described variations, the same effect is achieved as that of the tracker module 1c involved in embodiment 4.

[0351] (Modified Example)

[0352] Hereinafter, variations relating to embodiments 1 to 4 will be described.

[0353] (1) Variation Example 1

[0354] As a variation of embodiments 1 to 4, the tracker module 1, the first power amplifier 81, and the second power amplifier 82 can also be formed into a single power amplifier module. That is, the power amplifier module includes the tracker module 1, the first power amplifier 81, and the second power amplifier 82. The power amplifier module can also replace the tracker module 1 according to embodiment 1, and include the tracker module 1a according to embodiment 2, the tracker module 1b according to embodiment 3, or the tracker module 1c according to embodiment 4.

[0355] In the power amplifier module according to Modification 1, in the tracker module 1, three or more first output terminals 6 are arranged on the outermost periphery of the second main surface 22 of the substrate 2. As a result, it is easy to make leads from each first output terminal 6 in the substrate (mother substrate, etc.) on which the tracker module 1 is arranged.

[0356] (2) Variation Example 2

[0357] As a variation of embodiments 1 to 4, embodiment 2 can also consist of a tracker module 1, a first power amplifier 81, a second power amplifier 82, a first transmit filter 83, and a second transmit filter (not shown) forming a single module, namely a high-frequency module. The high-frequency module in embodiment 2 includes the tracker module 1, the first power amplifier 81, the second power amplifier 82, and the first transmit filters 83 and 84. The high-frequency module can also replace the tracker module 1 in embodiment 1, and include the tracker module 1a in embodiment 2, the tracker module 1b in embodiment 3, or the tracker module 1c in embodiment 4.

[0358] In the high-frequency module described in Modification 2, in the tracker module 1, three or more first output terminals 6 are arranged on the outermost periphery of the second main surface 22 of the substrate 2. Therefore, it is easy to draw out from each of the first output terminals 6 in the substrate (mother substrate, etc.) on which the tracker module 1 is arranged.

[0359] The embodiments and modifications described above are only a part of the various embodiments and modifications of the present invention. Furthermore, various changes can be made to the embodiments and modifications as long as they achieve the objectives of the present invention, depending on the design, etc.

[0360] In this specification, "an element disposed on the first main surface 21 of the substrate 2" includes not only the case where the element is directly mounted on the first main surface 21 of the substrate 2, but also the case where the element is disposed in the space on the first main surface 21 side, which is separated from the substrate 2 by the space on the first main surface 21 side and the space on the second main surface 22 side. That is, "an element disposed on the first main surface 21 of the substrate 2" includes the case where the element is mounted on the first main surface 21 of the substrate 2 via other circuit elements or electrodes, etc. Examples of elements include the tracker component 3 and the filter 4. However, the element is not limited to the tracker component 3 and the filter 4.

[0361] In this specification, "an element disposed on the second main surface 22 of the substrate 2" includes not only the case where the element is directly mounted on the second main surface 22 of the substrate 2, but also the case where the element is disposed in the space on the second main surface 22 side, which is separated from the first main surface 21 side by the substrate 2. That is, "an element disposed on the second main surface 22 of the substrate 2" includes the case where the element is mounted on the second main surface 22 of the substrate 2 via other circuit elements or electrodes, etc. Examples of elements include the first output terminal 6 and the second output terminal 7. However, the element is not limited to the first output terminal 6 and the second output terminal 7.

[0362] In this specification, "the first element overlaps with the second element when viewed from the thickness direction of the substrate 2" includes the following scenarios when viewed from the thickness direction of the substrate 2: the entire first element overlaps with the entire second element; the entire first element overlaps with a portion of the second element; a portion of the first element overlaps with the entire second element; and a portion of the first element overlaps with a portion of the second element. In short, "the first element overlaps with the second element when viewed from the thickness direction of the substrate 2" means "at least a portion of the first element overlaps with at least a portion of the second element." A combination of the first element and the second element could be, for example, a combination where the first element is a first output terminal 6 and the second element is a tracker component 3, or a combination where the first element is a second output terminal 7 and the second element is a tracker component 3. Furthermore, the combination of the first element and the second element is not limited to the combinations described above.

[0363] In this specification, "among the first, second, and third elements mounted on the substrate, "when viewed from the thickness direction of the substrate, a third element is disposed between the first and second elements" means that, when viewed from the thickness direction of the substrate, at least one of a plurality of line segments connecting any point in the first element to any point in the second element passes through at least a portion of the third element. Furthermore, "viewed from the thickness direction of the substrate" means that the substrate and the electronic components mounted on the substrate are projected orthographically onto a plane parallel to the main surface of the substrate.

[0364] (Way)

[0365] The following methods are disclosed in this specification.

[0366] The tracker module (1; 1a; 1b; 1c) involved in the first method outputs power supply voltages (V1; V2) to multiple power amplifiers.

[0367] According to the tracker module (1; 1a; 1b; 1c) involved in the first method, it is easy to make leads from each of the first output terminals (6) in the substrate (mother substrate, etc.) on which the tracker module (1; 1a; 1b; 1c) is configured. In other words, the wiring length between the first output terminal (6) connected to the first power amplifier (81) and the first power amplifier (81) can be shortened. In addition, the wiring layout between the first output terminal (6) connected to the first power amplifier (81) and the first power amplifier (81) can be simplified.

[0376] In the tracker module (1c) involved in the seventh method, in any one of the first to sixth methods, three or more first output terminals (6) are connected to the corresponding first power amplifier (81) via filters (4).

[0377] According to the tracker module (1c) involved in the seventh method, the noise component of the power supply voltage (V1) supplied to the first power amplifier (81) can be reduced.

[0378] In the tracker module (1c) involved in the eighth method, in the seventh method, the filter (4) is a low-pass filter.

[0379] In the tracker module (1a; 1b; 1c) involved in the ninth embodiment, in any one of the first to eighth embodiments, the plurality of external connection terminals (5) further include a second output terminal (7). The second output terminal (7) is different from the three or more first output terminals (6). The second output terminal (7) is connected to a second power amplifier (82) among the plurality of power amplifiers, and is disposed on the second main surface (22) of the substrate (2) at a position different from the outermost periphery.

[0380] In the tracker modules (1a; 1b; 1c) involved in the tenth method, in the ninth method, the maximum load current flowing through the second output terminal (7) is greater than the maximum load current flowing through each of the three or more first output terminals (6).

[0381] According to the tracker module (1a; 1b; 1c) involved in the tenth method, a larger power supply can be output to the second power amplifier (82) via the second output terminal (7).

[0384] In the tracker modules (1a; 1b; 1c) involved in the twelfth method, in any of the ninth to eleventh methods, the second output terminal (7) is connected to the second power amplifier (82) without passing through a filter.

[0385] In the tracker module (1a; 1b; 1c) involved in the thirteenth method, in any one of the ninth to twelfth methods, the three or more first power amplifiers (81) connected to the three or more first output terminals (6) are power amplifiers that amplify the FDD-based transmission signal. The second power amplifier (82) connected to the second output terminal (7) is a power amplifier that amplifies the TDD-based transmission signal.
