[0020] (Embodiment) [1 Circuit configuration of power supply circuit 1 and communication device 7] The circuit configuration of a power supply circuit 1 and a communication device 7 according to the present embodiment will be described with reference to Fig. 1. Fig. 1 is a circuit block diagram of the power supply circuit 1 and a communication device 7 according to the embodiment.

[0021] [1.1 Circuit configuration of communication device 7] First, a description will be given of a circuit configuration of the communication device 7. As shown in Fig. 1, the communication device 7 according to the present embodiment includes a power supply circuit 1, a power amplifier circuit 2, a filter 3, a PA control circuit 4, an RFIC (Radio Frequency Integrated Circuit) 5, and an antenna 6.

[0022] The power supply circuit 1 includes a pre-regulator circuit 10, a switched capacitor circuit 20, an output switch circuit 30, a filter circuit 40, and a DC power supply 50.

[0023] The power supply circuit 1 outputs a power supply voltage V having a power supply voltage level selected from a plurality of discrete voltage levels based on an envelope signal. ET 1, the power supply circuit 1 supplies one power supply voltage V ET However, a power supply voltage may be supplied to each of the power amplifiers individually.

[0024] The pre-regulator circuit 10 is an example of a third circuit, and includes a power inductor and a switch. The power inductor is an inductor used to step up and / or step down a DC voltage. The power inductor is arranged in series with the DC path. The pre-regulator circuit 10 can convert an input voltage (third voltage) to a first voltage using the power inductor. Such a pre-regulator circuit 10 may be called a magnetic regulator or a DC (Direct Current) / DC converter. The power inductor may be connected (arranged in parallel) between the series path and ground.

[0025] The pre-regulator circuit 10 does not have to have a power inductor, and may be, for example, a circuit that performs boosting by switching capacitors arranged in the series arm path and the parallel arm path of the pre-regulator circuit 10.

[0026] The switched-capacitor circuit 20 is an example of a first circuit, includes a plurality of capacitors and a plurality of switches, and can generate a plurality of discrete second voltages, each having a plurality of discrete voltage levels, from a first voltage from the pre-regulator circuit 10. The switched-capacitor circuit 20 is sometimes called a switched-capacitor voltage balancer.

[0027] The output switch circuit 30 is an example of a second circuit, and can selectively output at least one of the multiple discrete voltages (multiple second voltages) generated by the switched capacitor circuit 20 to the filter circuit 40 based on a digital control signal corresponding to the envelope signal. As a result, at least one voltage selected from the multiple discrete voltages is output from the output switch circuit 30. The output switch circuit 30 can change the output voltage over time by repeating such voltage selection over time.

[0028] Note that the output switch circuit 30 may include various circuit elements and / or wiring that generate voltage drops and / or noise, and therefore the time waveform of the output voltage of the output switch circuit 30 may not be a square wave that includes only a plurality of discrete voltages. In other words, the output voltage of the output switch circuit 30 may include a voltage other than the plurality of discrete voltages.

[0029] The filter circuit 40 is an example of a fourth circuit, and is capable of filtering the signal (second voltage) from the output switch circuit 30. The filter circuit 40 is configured, for example, by a low pass filter (LPF).

[0030] The DC power supply 50 can supply a DC voltage to the pre-regulator circuit 10. As the DC power supply 50, for example, a rechargeable battery can be used, but is not limited to this.

[0031] It should be noted that the power supply circuit 1 does not necessarily have to include at least one of the pre-regulator circuit 10, the filter circuit 40, and the DC power supply 50. For example, the power supply circuit 1 does not necessarily have to include the filter circuit 40 and the DC power supply 50. Also, any combination of the pre-regulator circuit 10, the switched capacitor circuit 20, the output switch circuit 30, and the filter circuit 40 may be integrated into a single circuit. A detailed circuit configuration example of the power supply circuit 1 will be described later with reference to FIG. 3.

[0032] The power amplifier circuit 2 is connected between the RFIC 5 and the filter 3, amplifies a high-frequency transmission signal (hereinafter referred to as the transmission signal) of a specific band output from the RFIC 5, and outputs the amplified transmission signal to the antenna 6 via the filter 3.

[0033] The PA control circuit 4 receives a control signal from the RFIC 5 to control the magnitude and supply timing of the bias current (or bias voltage) supplied to the power amplifier circuit 2.

[0034] The filter 3 is connected between the power amplifier circuit 2 and the antenna 6. The filter 3 has a pass band that includes a predetermined band. This allows the filter 3 to pass the transmission signal of the predetermined band amplified by the power amplifier circuit 2.

[0035] The antenna 6 is connected to the output side of the power amplifier circuit 2, and transmits the transmission signal of a predetermined band output from the power amplifier circuit 2.

[0036] The RFIC 5 is an example of a signal processing circuit that processes a radio frequency signal. Specifically, the RFIC 5 processes a transmission signal input from a BBIC (baseband signal processing circuit: not shown) by up-conversion or the like, and outputs the transmission signal generated by the signal processing to the power amplifier circuit 2.

[0037] The RFIC 5 is an example of a control circuit and has a control unit that controls the power supply circuit 1 and the power amplifier circuit 2. The RFIC 5 selects a power supply voltage V 1 to be used in the power amplifier circuit 2 from among a plurality of discrete voltage levels generated by the switched capacitor circuit 20, based on the envelope signal of the high frequency input signal obtained from the BBIC. ET This allows the output switch circuit 30 to select the voltage level of the power supply voltage V ET Output.

[0038] Note that a part or all of the functions of the RFIC 5 as the control unit may be provided outside the RFIC 5, for example, in the BBIC or the power supply circuit 1. For example, ET The control function for selecting the above may be provided in the power supply circuit 1, not in the RFIC 5.

[0039] The envelope signal is a signal that indicates the envelope of the high-frequency input signal (modulated wave). The envelope value is, for example, √(i 2 +Q 2), where (I,Q) represents a constellation point. A constellation point is a point on a constellation diagram that represents a signal modulated by digital modulation. (I,Q) is determined by the BBIC, for example, based on the transmitted information.

[0040] Tracking the envelope of a high-frequency signal using multiple discrete voltage levels within one frame is called digital envelope tracking (hereinafter referred to as digital ET), and the mode in which digital ET is applied to the power supply voltage is called digital ET mode. Tracking the envelope of a high-frequency signal using continuous voltage levels is called analog envelope tracking (hereinafter referred to as analog ET), and the mode in which analog ET is applied to the power supply voltage is called analog ET mode.

[0041] A frame is a unit that constitutes a high-frequency signal (modulated wave). For example, in 5GNR (5th Generation New Radio) and LTE (Long Term Evolution), a frame includes 10 subframes, each subframe includes multiple slots, and each slot is composed of multiple symbols. The subframe length is 1 ms, and the frame length is 10 ms.

[0042] The digital ET mode and the analog ET mode will now be described with reference to FIGS. 2A and 2B.

[0043] FIG. 2A is a graph showing an example of the transition of the power supply voltage in the digital ET mode. FIG. 2B is a graph showing an example of the transition of the power supply voltage in the analog ET mode. In FIG. 2A and FIG. 2B, the horizontal axis represents time, and the vertical axis represents voltage. Also, the thick solid line represents the power supply voltage V ET The thin solid line (waveform) represents a modulated wave.

[0044] In digital ET mode, the supply voltage V is scaled to multiple discrete voltage levels within one frame, as shown in Figure 2A. ETThe envelope of the modulating wave is tracked by varying . As a result, the power supply voltage signal forms a square wave. In digital ET mode, the envelope signal (√(i 2 +Q 2 )) a power supply voltage level is selected from among a plurality of discrete voltage levels.

[0045] In analog ET mode, the supply voltage V ET In analog ET mode, the power supply voltage V is adjusted based on the envelope signal. ET When the channel bandwidth is relatively small (e.g., less than 60 MHz), the analog ET is determined by the supply voltage V ET can follow the change in the envelope of the modulated wave, but when the channel bandwidth is relatively large (for example, 60 MHz or more), the power supply voltage V ET In other words, when the channel bandwidth is relatively large, the power supply voltage V ET The change in amplitude of the modulated wave is delayed with respect to the change in the envelope of the modulated wave.

[0046] On the other hand, when the channel bandwidth is relatively large (e.g., 60 MHz or more), the power supply voltage V ET The response to the modulated wave is improved.

[0047] Note that the communication device 7 shown in FIG. 1 is an example and is not limited thereto. For example, the communication device 7 may not include the filter 3, the PA control circuit 4, and the antenna 6. Furthermore, the communication device 7 may include a receiving path having a low noise amplifier and a receiving filter. Also, for example, the communication device 7 may include a plurality of power amplifier circuits corresponding to different bands.

[0048] [1.2 Circuit configuration of power supply circuit 1] Next, the circuit configurations of the pre-regulator circuit 10, the switched capacitor circuit 20, the output switch circuit 30, and the filter circuit 40 included in the power supply circuit 1 will be described with reference to Fig. 3. Fig. 3 is a diagram showing an example of the circuit configuration of the power supply circuit 1 according to an embodiment.

[0049] 3 is an exemplary circuit configuration, and the pre-regulator circuit 10, the switched capacitor circuit 20, the output switch circuit 30, and the filter circuit 40 may be implemented using any of a wide variety of circuit implementations and circuit technologies, and therefore the description of each circuit provided below should not be construed as limiting.

[0050] [1.2.1 Circuit configuration of the switched-capacitor circuit 20] First, a description will be given of the circuit configuration of the switched capacitor circuit 20. The switched capacitor circuit 20 includes capacitors C11, C12, C13, C14, C15, and C16, capacitors C10, C20, C30, and C40, switches S11, S12, S13, S14, S21, S22, S23, S24, S31, S32, S33, S34, S41, S42, S43, and S44, and a control terminal 120, as shown in FIG.

[0051] The control terminal 120 is an input terminal for a digital control signal. In other words, the control terminal 120 is a terminal for receiving a digital control signal for controlling the switched capacitor circuit 20. As the digital control signal received via the control terminal 120, for example, a source synchronous control signal that transmits a data signal and a clock signal can be used, but is not limited to this. For example, a clock embedded method may be applied to the digital control signal.

[0052] Each of the capacitors C11 to C16 functions as a flying capacitor (sometimes called a transfer capacitor). That is, each of the capacitors C11 to C16 is used to step up or step down the first voltage supplied from the pre-regulator circuit 10. More specifically, the capacitors C11 to C16 transfer charges between the capacitors C11 to C16 and the nodes N1 to N4 so that voltages V1 to V4 (voltages relative to the ground potential) that satisfy V1:V2:V3:V4=1:2:3:4 are maintained at the four nodes N1 to N4. The voltages V1 to V4 correspond to a plurality of discrete second voltages each having a plurality of discrete voltage levels.

[0053] The capacitor C11 has two electrodes. One of the two electrodes of the capacitor C11 is connected to one end of the switch S11 and one end of the switch S12. The other of the two electrodes of the capacitor C11 is connected to one end of the switch S21 and one end of the switch S22.

[0054] The capacitor C12 is an example of a first capacitor and has two electrodes (an example of a first electrode and a second electrode). One of the two electrodes of the capacitor C12 is connected to one end of the switch S21 and one end of the switch S22. The other of the two electrodes of the capacitor C12 is connected to one end of the switch S31 and one end of the switch S32.

[0055] The capacitor C13 has two electrodes. One of the two electrodes of the capacitor C13 is connected to one end of the switch S31 and one end of the switch S32. The other of the two electrodes of the capacitor C13 is connected to one end of the switch S41 and one end of the switch S42.

[0056] The capacitor C14 has two electrodes. One of the two electrodes of the capacitor C14 is connected to one end of the switch S13 and one end of the switch S14. The other of the two electrodes of the capacitor C14 is connected to one end of the switch S23 and one end of the switch S24.

[0057] The capacitor C15 is an example of a second capacitor and has two electrodes (an example of a third electrode and a fourth electrode). One of the two electrodes of the capacitor C15 is connected to one end of the switch S23 and one end of the switch S24. The other of the two electrodes of the capacitor C15 is connected to one end of the switch S33 and one end of the switch S34.

[0058] The capacitor C16 has two electrodes. One of the two electrodes of the capacitor C16 is connected to one end of the switch S33 and one end of the switch S34. The other of the two electrodes of the capacitor C16 is connected to one end of the switch S33 and one end of the switch S34. 43 One end of the switch S 44 is connected to one end of the

[0059] The capacitors C11 and C13 are also an example of a first capacitor, and the capacitors C14 and C16 are also an example of a second capacitor.

[0060] The set of capacitors C11 and C14, the set of capacitors C12 and C15, and the set of capacitors C13 and C16 can be charged and discharged in a complementary manner by repeating the first and second phases.

[0061] Specifically, in the first phase, the switches S12, S13, S22, S23, S32, S33, S42 and S43 are turned on, so that, for example, one of the two electrodes of the capacitor C12 is connected to the node N3, the other of the two electrodes of the capacitor C12 and one of the two electrodes of the capacitor C15 are connected to the node N2, and the other of the two electrodes of the capacitor C15 is connected to the node N1.

[0062] On the other hand, in the second phase, the switches S11, S14, S21, S24, S31, S34, S41 and S44 are turned on, so that, for example, one of the two electrodes of the capacitor C15 is connected to the node N3, the other of the two electrodes of the capacitor C15 and one of the two electrodes of the capacitor C12 are connected to the node N2, and the other of the two electrodes of the capacitor C12 is connected to the node N1.

[0063] By repeating such a first phase and a second phase, for example, when one of the capacitors C12 and C15 is being charged from the node N2, the other of the capacitors C12 and C15 can be discharged to the capacitor C30. That is, the capacitors C12 and C15 can charge and discharge in a complementary manner. The capacitors C12 and C15 are a pair of flying capacitors that charge and discharge in a complementary manner.

[0064] In addition, by switching the switches appropriately, a set of any of capacitors C11, C12, and C13 (first capacitors) and any of C14, C15, and C16 (second capacitors) can become a pair of flying capacitors that complementarily charge from the node and discharge to the smoothing capacitor, similar to the set of capacitors C12 and C15.

[0065] Each of the capacitors C10, C20, C30 and C40 functions as a smoothing capacitor, that is, each of the capacitors C10, C20, C30 and C40 is used to hold and smooth the voltages V1 to V4 at the nodes N1 to N4.

[0066] The capacitor C10 is an example of a third capacitor and is connected between the node N1 and the ground.

[0071] The switch S12 is connected between one of the two electrodes of the capacitor C11 and the node N4. Specifically, one end of the switch S12 is connected to one of the two electrodes of the capacitor C11. Meanwhile, the other end of the switch S12 is connected to the node N4.

[0072] The switch S21 is an example of a first switch, and is connected between one of the two electrodes of the capacitor C12 and the node N2. Specifically, one end of the switch S21 is connected to one of the two electrodes of the capacitor C12 and the other of the two electrodes of the capacitor C11. Meanwhile, the other end of the switch S21 is connected to the node N2.

[0081] The switch S24 is an example of a seventh switch, and is connected between one of the two electrodes of the capacitor C15 and the node N3. Specifically, one end of the switch S24 is connected to one of the two electrodes of the capacitor C15 and the other of the two electrodes of the capacitor C14.

[0082] The switch S33 is an example of an eighth switch, and is connected between the other of the two electrodes of the capacitor C15 and the node N1. Specifically, one end of the switch S33 is connected to the other of the two electrodes of the capacitor C15 and one of the two electrodes of the capacitor C16.

[0083] The switch S34 is an example of a sixth switch, and is connected between the other of the two electrodes of the capacitor C15 and the node N2. Specifically, one end of the switch S34 is connected to the other of the two electrodes of the capacitor C15 and one of the two electrodes of the capacitor C16.

[0086] A first set of switches including switches S12, S13, S22, S23, S32, S33, S42, and S43 and a second set of switches including switches S11, S14, S21, S24, S31, S34, S41, and S44 are switched on and off in a complementary manner. Specifically, in a first phase, the first set of switches are turned on and the second set of switches are turned off. Conversely, in a second phase, the first set of switches are turned off and the second set of switches are turned on.

[0087] For example, in one of the first and second phases, charging of the capacitors C10 to C40 is performed from the capacitors C11 to C13, and in the other of the first and second phases, charging of the capacitors C10 to C40 is performed from the capacitors C14 to C16. That is, since the capacitors C10 to C40 are always charged from the capacitors C11 to C13 or the capacitors C14 to C16, even if a current flows at high speed from the nodes N1 to N4 to the output switch circuit 30, charges are replenished at high speed to the nodes N1 to N4, so that fluctuations in the potential of the nodes N1 to N4 can be suppressed.

[0088] By operating in this manner, the switched capacitor circuit 20 can maintain approximately equal voltages across each of the capacitors C10, C20, C30, and C40. Specifically, voltages V1 to V4 (voltages relative to ground potential) that satisfy V1:V2:V3:V4=1:2:3:4 are maintained at four nodes labeled V1 to V4. The voltage levels of the voltages V1 to V4 correspond to a plurality of discrete voltage levels supplied by the switched capacitor circuit 20 to the output switch circuit 30.

[0089] It should be noted that the voltage ratio V1:V2:V3:V4 is not limited to 1:2:3:4. For example, the voltage ratio V1:V2:V3:V4 may be 1:2:4:8.

[0090] The configuration of the switched capacitor circuit 20 shown in FIG. 3 is an example, and is not limited thereto. In FIG. 3, the switched capacitor circuit 20 is configured to be capable of supplying voltages of four discrete voltage levels, but is not limited thereto. The switched capacitor circuit 20 may be configured to be capable of supplying voltages of any number of discrete voltage levels, which is two or more. For example, when voltages of two discrete voltage levels are supplied, the switched capacitor circuit 20 may include at least capacitors C12 and C15, and switches S21, S22, S31, S32, S23, S24, S33, and S34.

[0091] [1.2.2 Circuit configuration of output switch circuit 30] Next, a description will be given of the circuit configuration of the output switch circuit 30. The output switch circuit 30 includes input terminals 131 to 134, switches S51, S52, S53 and S54, an output terminal 130, and a control terminal 135, as shown in FIG.

[0092] The output terminal 130 is connected to the filter circuit 40. The output terminal 130 outputs at least one voltage selected from the voltages V1 to V4 to the power amplifier circuit 2 via the filter circuit 40 as a power supply voltage V ET As described above, the output switch circuit 30 may include various circuit elements and / or wiring that generate voltage drops and / or noise, so the power supply voltage V observed at the output terminal 130 may be ET may include voltages different from the voltages V1 to V4.

[0093] The input terminals 131 to 134 are respectively connected to the nodes N4 to N1 of the switched capacitor circuit 20. The input terminals 131 to 134 are terminals for receiving the voltages V4 to V1 from the switched capacitor circuit 20.

[0094] The control terminal 135 is an input terminal for a digital control signal. That is, the control terminal 135 is a terminal for receiving a digital control signal indicating one of the voltages V1 to V4. The output switch circuit 30 controls the on / off of the switches S51 to S54 so as to select the voltage level indicated by the digital control signal.

[0095] Two digital control logic (DCL: Digital Control Logic / Line) signals can be used as the digital control signal received via the control terminal 135. Each of the two DCL signals is a 1-bit signal. One of the voltages V1 to V4 is represented by a combination of two 1-bit signals. For example, V1, V2, V3, and V4 are represented by "00", "01", "10", and "11", respectively. A Gray code may be used to represent the voltage levels. In this case, two control terminals are provided to receive the two DCL signals. The number of DCL signals may be any number equal to or greater than one depending on the number of voltage levels. The DCL signal may be a signal of 2 or more bits. The digital control signal may be one or more DCL signals, or a source synchronous control signal may be used.

[0096] The switch S51 is connected between the input terminal 131 and the output terminal 130. Specifically, the switch S51 has a terminal connected to the input terminal 131 and a terminal connected to the output terminal 130. In this connection configuration, the switch S51 can switch between connection and non-connection between the input terminal 131 and the output terminal 130 by switching on / off.

[0097] The switch S52 is an example of a tenth switch, and is connected between the input terminal 132 and the output terminal 130. Specifically, the switch S52 has a terminal connected to the input terminal 132 and a terminal connected to the output terminal 130. In this connection configuration, the switch S52 can switch between connection and non-connection between the input terminal 132 and the output terminal 130 by switching on / off.

[0098] The switch S53 is an example of a ninth switch, and is connected between the input terminal 133 and the output terminal 130. Specifically, the switch S53 has a terminal connected to the input terminal 133 and a terminal connected to the output terminal 130. In this connection configuration, the switch S53 can switch between connection and non-connection between the input terminal 133 and the output terminal 130 by switching on / off.

[0099] The switch S54 is connected between the input terminal 134 and the output terminal 130. Specifically, the switch S54 has a terminal connected to the input terminal 134 and a terminal connected to the output terminal 130. In this connection configuration, the switch S54 can switch between connection and non-connection between the input terminal 134 and the output terminal 130 by switching on / off.

[0100] These switches S51 to S54 are controlled to be exclusively on. That is, only one of the switches S51 to S54 is turned on, and the remaining switches S51 to S54 are turned off. This allows the output switch circuit 30 to output one voltage selected from the voltages V1 to V4.

[0101] 3 is an example, and is not limited thereto. In particular, the switches S51 to S54 may have any configuration as long as they can select one of the four input terminals 131 to 134 and connect it to the output terminal 130. For example, the output switch circuit 30 may further include a switch connected between the switches S51 to S53 and the switch S54 and the output terminal 130. Also, for example, the output switch circuit 30 may further include a switch connected between the switches S51 and S52 and the switches S53 and S54 and the output terminal 130.

[0102] Also, for example, when selecting one voltage from the second voltages having two discrete voltage levels, the output switch circuit 30 may include at least the switches S52 and S53.

[0103] Furthermore, the output switch circuit 30 may be configured to be able to output two or more voltages. In this case, the output switch circuit 30 may further include a required number of additional switch sets similar to the set of switches S51-S54 and additional output terminals.

[0104] [1.2.3 Circuit configuration of pre-regulator circuit 10] Next, a description will be given of the circuit configuration of the pre-regulator circuit 10.

[0112] The switch S71 is an example of an eleventh switch, and is connected between the input terminal 110 and one end of the power inductor L71. Specifically, the switch S71 has a terminal connected to the input terminal 110, and a terminal connected to one end of the power inductor L71 via the inductor connection terminal 115. In this connection configuration, the switch S71 can switch between connection and non-connection between the input terminal 110 and one end of the power inductor L71 by switching on / off.

[0113] The switch S72 is an example of a twelfth switch, and is connected between one end of the power inductor L71 and the ground. Specifically, the switch S72 has a terminal connected to one end of the power inductor L71 via the inductor connection terminal 115, and a terminal connected to the ground. In this connection configuration, the switch S72 can switch between connection and non-connection between the one end of the power inductor L71 and the ground by switching on / off.

[0114] The switch S61 is connected between the other end of the power inductor L71 and the output terminal 111. Specifically, the switch S61 has a terminal connected to the other end of the power inductor L71 and a terminal connected to the output terminal 111. In this connection configuration, the switch S61 can switch between connection and non-connection between the other end of the power inductor L71 and the output terminal 111 by switching on / off.

[0115] The switch S62 is connected between the other end of the power inductor L71 and the output terminal 112. Specifically, the switch S62 has a terminal connected to the other end of the power inductor L71 and a terminal connected to the output terminal 112. In this connection configuration, the switch S62 can switch between connection and non-connection between the other end of the power inductor L71 and the output terminal 112 by switching on / off.

[0116] The switch S63 is connected between the other end of the power inductor L71 and the output terminal 113. Specifically, the switch S63 has a terminal connected to the other end of the power inductor L71 and a terminal connected to the output terminal 113. In this connection configuration, the switch S63 can switch between connection and non-connection between the other end of the power inductor L71 and the output terminal 113 by switching on / off.

[0117] The capacitor C61 is connected between the output terminal 111 and the output terminal 112. One of the two electrodes of the capacitor C61 is connected to the switch S61 and the output terminal 111, and the other of the two electrodes of the capacitor C61 is connected to the switch S62, the output terminal 112, and one of the two electrodes of the capacitor C62.

[0118] The capacitor C62 is connected between the output terminal 112 and the output terminal 113. One of the two electrodes of the capacitor C62 is connected to the switch S62, the output terminal 112, and the other of the two electrodes of the capacitor C61, and the other of the two electrodes of the capacitor C62 is connected to a path that connects the switch S63, the output terminal 113, and one of the two electrodes of the capacitor C63.

[0119] Capacitor C63 is an example of a fourth capacitor, and is connected between output terminal 113 and output terminal 114. One of two electrodes of capacitor C63 is connected to switch S63, output terminal 113, and the other of two electrodes of capacitor C62, and the other of two electrodes of capacitor C63 is connected to output terminal 114 and one of two electrodes of capacitor C64.

[0120] The capacitor C64 is connected between the output terminal 114 and ground. One of the two electrodes of the capacitor C64 is connected to the output terminal 114 and the other of the two electrodes of the capacitor C63, and the other of the two electrodes of the capacitor C64 is connected to ground.

[0121] The switches S61 to S63 are controlled to be exclusively on. That is, only one of the switches S61 to S63 is turned on, and the remaining switches S61 to S63 are turned off. Depending on which of the switches S61 to S63 is turned on, it is possible to change the voltage levels of the voltages V1 to V4.

[0122] The pre-regulator circuit 10 thus configured supplies electric charge to the switched capacitor circuit 20 via at least one of the output terminals 111-113.

[0123] When converting the input voltage (third voltage) into one first voltage, the pre-regulator circuit 10 only needs to include at least the switches S71 and S72 and the power inductor L71.

[0124] [1.2.4 Circuit configuration of filter circuit 40] Next, a description will be given of the circuit configuration of the filter circuit 40. The filter circuit 40 includes inductors L51, L52, and L53, capacitors C51 and C52, a resistor R51, an input terminal 140, and an output terminal 141, as shown in FIG.

[0125] The input terminal 140 is an input terminal for the second voltage selected by the output switch circuit 30. In other words, the input terminal 140 is a terminal for receiving the second voltage selected from among the multiple voltages V1 to V4.

[0126] The output terminal 141 is the power supply voltage V ET That is, the output terminal 141 outputs the power supply voltage V ET This is a terminal for supplying

[0127] Inductor L51 and inductor L52 are connected in series between input terminal 140 and output terminal 141. A series circuit of inductor L53 and resistor R51 is connected in parallel to inductor L51. Capacitor C51 is connected between the connection point of inductors L51 and L52 and ground. Capacitor C52 is connected between output terminal 141 and ground.

[0128] In the above configuration, the filter circuit 40 configures an LC low-pass filter in which an inductor is arranged in a series arm path and a capacitor is arranged in a parallel arm path. This allows the filter circuit 40 to reduce high-frequency components contained in the power supply voltage. For example, when the predetermined band is a frequency band for Frequency Division Duplex (FDD), the filter circuit 40 is configured to reduce components of the downlink operating band of the predetermined band.

[0129] 3 is merely an example, and the present invention is not limited to this example. The filter circuit 40 may be configured as a band-pass filter or a high-pass filter depending on the band to be removed.

[0130] The filter circuit 40 may also include two or more LC filters. The two or more LC filters may be commonly connected to the output terminal 130, and each LC filter may have a pass band or an attenuation band corresponding to each of the different bands. Alternatively, a first filter group consisting of two or more LC filters may be connected to a first output terminal of the output switch circuit 30, and a second filter group consisting of another two or more LC filters may be connected to a second output terminal of the output switch circuit 30, and each LC filter may have a pass band or an attenuation band corresponding to each of the different bands. In this case, the filter circuit 40 has two or more output terminals and can simultaneously output two or more power supply voltages V ET may be output.

[0131] Here, when configuring a tracker module in which the switches of the switched capacitor circuit 20 and the output switch circuit 30 are mounted on a module board as one-chip switch integrated circuits, it is assumed that the wiring connecting the switches of the switched capacitor circuit 20 and the capacitors will be long. By applying digital ET to the wiring, a large current will flow due to the high-speed charging and discharging of the capacitors. For this reason, the wiring is required to be able to pass a large current with low resistance, but as the wiring becomes longer, the resistance loss in the wiring increases, and if the wiring is made thicker to avoid the resistance loss, the impedance will shift, and the power supply voltage V output from the tracker module will become large. ET This may cause the output waveform to deteriorate.

[0132] In the following, in a tracker module equipped with the power supply circuit 1 according to the present embodiment, the power supply voltage V ET A configuration for suppressing the deterioration of the output characteristics will be described.

[0133] [2. Component Arrangement of Tracker Module 100 According to the Second Embodiment] Fig. 4 is a plan view of the tracker module 100 according to the embodiment. Fig. 5 is a first cross-sectional view of the tracker module 100 according to the embodiment, specifically, a cross-sectional view taken along line VV in Fig. 4. Fig. 6 is a second cross-sectional view of the tracker module 100 according to the embodiment, specifically, a cross-sectional view taken along line VI-VI in Fig. 4. Fig. 4 shows a layout of circuit components when the main surface 90a of the module substrate 90 facing each other is viewed from the z-axis positive direction.

[0134] The tracker module 100 according to this embodiment specifically illustrates the layout of some of the circuit components that make up the power supply circuit 1 according to the embodiment.

[0135] As shown in Figures 4 to 6, the tracker module 100 of this embodiment includes a module substrate 90, an integrated circuit 80, capacitors C10, C20, C30, C40, C11, C12, C13, C14, C15, C16, C51, C52, C61, C62, C63 and C64, inductors L51, L52 and L53, a resistor R51, and a resin member 91.

[0136] The module substrate 90 has two opposing main surfaces 90a and 90b, and is a substrate on which circuit components constituting the tracker module 100 are mounted. As the module substrate 90, for example, a low temperature co-fired ceramics (LTCC) substrate having a laminated structure of multiple dielectric layers, a high temperature co-fired ceramics (HTCC) substrate, a substrate with embedded components, a substrate having a redistribution layer (RDL), a printed circuit board, or the like is used.

[0137] The integrated circuit 80 is a semiconductor IC (Integrated Circuit) and is configured, for example, using a CMOS (Complementary Metal Oxide Semiconductor), specifically, manufactured by a SOI (Silicon on Insulator) process. The integrated circuit 80 may be configured of at least one of GaAs, SiGe, and GaN. Note that the semiconductor material of the integrated circuit 80 is not limited to the above-mentioned materials.

[0138] The integrated circuit 80 includes a PR switch section 10A, an SC switch section 20A, an OS switch section 30A, and a plurality of input / output electrodes 81.

[0139] The PR switch unit 10A is configured with switches included in the pre-regulator circuit 10. Specifically, the PR switch unit 10A includes switches S61, S62, S63, S71, and S72.

[0140] The SC switch section 20A is configured with switches included in the switched capacitor circuit 20. Specifically, the SC switch section 20A includes switches S11, S12, S13, S14, S21, S22, S23, S24, S31, S32, S33, S34, S41, S42, S43 and S44.

[0141] The OS switch section 30A is configured with switches included in the output switch circuit 30. Specifically, the OS switch section 30A includes switches S51, S52, S53, and S54.

[0142] Capacitors C10, C20, C30, C40, C11, C12, C13, C14, C15, and C16 are capacitors included in the switched capacitor circuit 20. Capacitors C51 and C52 are capacitors included in the filter circuit 40. Capacitors C61, C62, C63, and C64 are capacitors included in the pre-regulator circuit 10.

[0143] The multiple input / output electrodes 81 are electrically connected to the multiple circuit components arranged on the main surface 90a or the multiple external connection electrodes 150 arranged on the main surface 90b through a wiring layer or via conductors formed on the module substrate 90. The multiple input / output electrodes 81 include an input electrode 811.

[0144] The input electrode 811 is an example of an input terminal, and is connected to the RFIC 5 disposed outside the tracker module 100 via the external connection electrode 150 (control terminal 135).

[0145] The resin member 91 is disposed on the main surface 90a, and covers the main surface 90a and some of the circuit components that make up the tracker module 100. The resin member 91 has the function of ensuring reliability such as mechanical strength and moisture resistance of the circuit components that make up the tracker module 100. Note that the resin member 91 is not an essential component of the tracker module 100 according to this embodiment.

[0146] It should be noted that the tracker module 100 only needs to include at least one of the capacitors C10-C64 included in the switched capacitor circuit 20. The integrated circuit 80 only needs to have an SC switch section 20A and an OS switch section 30A, and further, the SC switch section 20A only needs to have at least one of the switches S11-S44 described above, and the OS switch section 30A only needs to have at least one of the switches S51-S54 described above.

[0147] Furthermore, integrated circuit 80 may have an SC switch unit 20A and an OS switch unit 30A, and an integrated circuit different from integrated circuit 80 may have a PR switch unit 10A. In this case, only integrated circuit 80 of the two integrated circuits may be arranged on module substrate 90, or both integrated circuits may be arranged on module substrate 90.

[0148] Furthermore, external connection electrodes 150 are arranged on the main surface 90b. The tracker module 100 exchanges electrical signals with the RFIC 5, the power amplifier circuit 2, and an external substrate arranged on the negative z-axis side of the tracker module 100, via the multiple external connection electrodes 150. Furthermore, some of the multiple external connection electrodes 150 are set to ground potential.

[0149] As shown in FIGS. 5 and 6, the external connection electrodes 150 may be planar electrodes, or may be bump electrodes formed on the main surface 90b.

[0150] Although not shown in Fig. 4, wiring connecting each circuit component shown in Fig. 3 is formed on the main surfaces 90a and 90b inside the module substrate 90. The wiring may be a bonding wire having both ends bonded to either the main surfaces 90a, 90b or the circuit components, or may be a terminal, electrode, or wiring formed on the surface of the circuit components.

[0151] In tracker module 100, integrated circuit 80 and capacitor C11 are adjacent to each other, integrated circuit 80 and capacitor C13 are adjacent to each other, integrated circuit 80 and capacitor C14 are adjacent to each other, integrated circuit 80 and capacitor C15 are adjacent to each other, and integrated circuit 80 and capacitor C16 are adjacent to each other.

[0152] In this embodiment, the integrated circuit 80 and the capacitor C11 being adjacent to each other means that the integrated circuit 80 and the capacitor C11 are disposed in close proximity to each other, and specifically means that no circuit components are present in the space between the side of the integrated circuit 80 and the side of the capacitor C11 that face each other. The circuit components include active components such as transistors and diodes, and passive components such as inductors, transformers, capacitors, and resistors, but do not include terminals, connectors, electrodes, wiring, resin members, etc.

[0153] In the switched capacitor circuit 20, the capacitors repeatedly charge and discharge at high speed, so that a plurality of highly accurate and stable second voltages can be supplied to the output switch circuit 30. For this reason, it is desirable that the wiring connecting the capacitors and the switches connected to the capacitors can transfer charges at high speed and with low resistance.

[0154] In contrast, by arranging the integrated circuit 80 and the capacitor of the switched capacitor circuit 20 adjacent to each other, the wiring connecting the capacitor and the switch of the SC switch section 20A can be shortened, so that the parasitic resistance and parasitic inductance of the wiring in the switched capacitor circuit 20 can be reduced. Therefore, the switched capacitor circuit 20 can supply a plurality of highly accurate and stable second voltages to the output switch circuit 30, so that the power supply voltage V ET This can suppress deterioration of the output waveform.

[0155] In this embodiment, the SC switch section 20A of the integrated circuit 80 and the capacitor C11 are adjacent to each other.

[0156] According to this, the wiring connecting the capacitor C11 and the switch of the SC switch section 20A can be made shorter, so that the parasitic resistance and parasitic inductance of the wiring in the switched capacitor circuit 20 can be made smaller.

[0157] It is sufficient that at least one of the capacitors C10 to C16 is adjacent to the integrated circuit 80. This allows the wiring connecting the at least one capacitor and the switch of the SC switch section 20A to be short, thereby reducing the parasitic resistance and parasitic inductance of the wiring. Therefore, a plurality of highly accurate and stable third-party capacitors can be output from the switched capacitor circuit 20. 2 A voltage may be provided to the output switch circuit 30 .

[0158] It is preferable that the integrated circuit 80 and the capacitor C11 are adjacent to each other and / or that the integrated circuit 80 and the capacitor C14 are adjacent to each other.

[0159] Of the multiple capacitors included in the switched capacitor circuit 20, the capacitors C11 and C14 are the capacitors to which the highest potential (voltage V4) is applied. Therefore, the amount of charge transfer is maximum in the wiring connected to the capacitor C11 and the wiring connected to the capacitor C14. In contrast, by shortening the wiring, the switched capacitor circuit 20 can supply the second voltage having a highly accurate and stable high voltage level to the output switch circuit 30, and the power supply voltage V output from the tracker module 100 can be reduced. ET This effectively prevents the output waveform from deteriorating.

[0160] In addition, in the plan view, integrated circuit 80 has a rectangular outer periphery and has four sides 801, 802, 803, and 804. Capacitor C14 is adjacent to side 801 (first side), and capacitor C15 is adjacent to side 802 (second side).

[0161] This allows the heat generated from the wiring connected to capacitor C14 and the wiring connected to capacitor C15 to be dispersed and dissipated while shortening the length of the wiring, thereby improving the heat dissipation performance of tracker module 100. Note that the combination of two capacitors dispersedly arranged on two different sides of integrated circuit 80 is not limited to capacitors C14 and C15, and may be any combination of two capacitors among the multiple capacitors included in switched capacitor circuit 20.

[0162] Each of the capacitors C13, C10, and C16 is adjacent to the side 802. The capacitors C13 and C16 are a pair of flying capacitors that charge and discharge complementarily. The capacitor C10 is a smoothing capacitor that smoothes the voltages of the capacitors C13 and C16 and the voltage of the node N1.

[0163] This allows the wiring connecting the capacitors C13, C10, and C16 to be short, thereby reducing the parasitic resistance and parasitic inductance of the wiring. Therefore, the switched capacitor circuit 20 can supply a plurality of highly accurate and stable second voltages to the output switch circuit 30.

[0164] Furthermore, the capacitor C10 is disposed between the capacitors C13 and C16.

[0165] According to this, since the smoothing capacitor is disposed between the pair of flying capacitors, the interaction of heat generated from the capacitors C13 and C16 can be reduced, and heat dissipation is effectively improved and characteristic degradation is suppressed.

[0166] Additionally, each of the capacitors C61, C62, C63 and C64 is adjacent to the integrated circuit 80.

[0167] According to this, since the integrated circuit 80 and the capacitor of the pre-regulator circuit 10 are adjacent to each other, the wiring connecting the capacitor and the switch of the PR switch section 10A can be shortened, so that the parasitic resistance and parasitic inductance of the wiring in the pre-regulator circuit 10 can be reduced. Therefore, the pre-regulator circuit 10 can supply a highly accurate and stable first voltage to the switched capacitor circuit 20, and the power supply voltage V output from the tracker module 100 can be reduced. ET This can suppress deterioration of the output waveform.

[0168] In this embodiment, the PR switch section 10A of the integrated circuit 80 and the capacitors C61 to C64 are adjacent to each other.

[0169] This allows the wiring connecting the capacitors C61-C64 and the switches of the PR switch section 10A to be shorter, thereby reducing the parasitic resistance and parasitic inductance of the wiring in the pre-regulator circuit 10. Therefore, ringing caused by the parasitic inductance when the switches of the PR switch section 10A are switched can be suppressed.

[0170] At least one of the capacitors C61 to C64 and the integrated circuit 80 need only be adjacent to each other.

[0171] In this embodiment, the integrated circuit 80 is adjacent to the inductors L51, L53, and the capacitor C51.

[0172] According to this, since the integrated circuit 80 and the circuit components of the filter circuit 40 are adjacent to each other, the wiring connecting the circuit components and the switches of the OS switch section 30A can be shortened, and the parasitic resistance and parasitic inductance of the wiring connecting the filter circuit 40 and the output switch circuit 30 can be reduced. Therefore, a highly accurate and stable power supply voltage V ET can be output.

[0173] In this embodiment, OS switch section 30A of integrated circuit 80 is adjacent to inductors L51, L53, and capacitor C51.

[0174] This allows the wiring connecting inductors L51, L53 and capacitor C51 to the switches of OS switch section 30A to be shorter, thereby reducing the parasitic resistance and parasitic inductance of the wiring connecting filter circuit 40 to output switch circuit 30. This prevents the deterioration of the pass characteristics and attenuation characteristics of filter circuit 40 caused by a decrease in the Q value of the inductance of the wiring due to parasitic resistance.

[0175] The tracker module 100 according to this embodiment also includes a module substrate 90, a pre-regulator circuit 10 (excluding the power inductor L71), a switched capacitor circuit 20, an output switch circuit 30, and a filter circuit 40.

[0176] The switched capacitor circuit 20 has switches S11 to S44 and capacitors C10 to C16, and the output switch circuit 30 has switches S51 to S54. The switches S11 to S44 and the switches S51 to S54 are included in an integrated circuit 80. The capacitors C10 to C16 and the integrated circuit 80 are disposed on a module substrate 90. Here, the integrated circuit 80 and at least one of the capacitors C10 to C16 are adjacent to each other.

[0177] According to this, since the integrated circuit 80 and the capacitor of the switched capacitor circuit 20 are adjacent to each other, the wiring connecting the capacitor and the switch of the SC switch section 20A can be shortened, and the parasitic resistance and parasitic inductance of the wiring in the switched capacitor circuit 20 can be reduced. 2 A voltage can be supplied to the output switch circuit 30, and the power supply voltage V ET This can suppress deterioration of the output waveform.

[0178] It should be noted that the tracker module 100 does not necessarily have to include the pre-regulator circuit 10 and the filter circuit 40.

[0179] [3 Effects, etc.] As described above, the tracker module 100 of this embodiment comprises a module substrate 90, an integrated circuit 80 arranged on the module substrate 90, and a capacitor included in a switched capacitor circuit 20 arranged on the module substrate 90 and configured to generate a plurality of discrete voltages based on an input voltage, the integrated circuit 80 including a switch included in the switched capacitor circuit 20 and a switch included in an output switch circuit 30 configured to selectively output at least one of the plurality of discrete voltages based on an envelope signal, and the integrated circuit 80 and the capacitor are adjacent to each other.

[0180] By applying digital ET, in the switched capacitor circuit 20, the capacitors are required to repeatedly charge and discharge at high speed, and to supply a plurality of discrete voltages with large fluctuations with high accuracy and stability to the output switch circuit 30. For this reason, it is desirable for the wiring connecting the capacitors and the switches connected to the capacitors to be able to transfer charges at high speed and with low resistance.

[0181] According to the above configuration, since the integrated circuit 80 and the capacitor of the switched capacitor circuit 20 are adjacent to each other, the wiring connecting the capacitor and the switch of the SC switch section 20A can be shortened, so that the parasitic resistance and parasitic inductance of the wiring in the switched capacitor circuit 20 can be reduced. Therefore, the switched capacitor circuit 20 can supply a plurality of highly accurate and stable discrete voltages to the output switch circuit 30, so that the power supply voltage V output from the tracker module 100 can be reduced. ET This can suppress deterioration of the output waveform.

[0182] In addition, the tracker module 100 of this embodiment includes a module substrate 90, a switched capacitor circuit 20 configured to generate a plurality of discrete voltages based on an input voltage, and an output switch circuit 30 having an input electrode 811 connected to a control circuit and configured to selectively output at least one of the plurality of discrete voltages, wherein the switched capacitor circuit 20 has a switch and a capacitor, the output switch circuit 30 has a switch, the switch of the switched capacitor circuit 20 and the switch of the output switch circuit 30 are included in an integrated circuit 80, the capacitor and the integrated circuit 80 are arranged on the module substrate 90, and the integrated circuit 80 and the capacitor are adjacent to each other.

[0183] According to the above configuration, the integrated circuit 80 and the capacitor of the switched capacitor circuit 20 are adjacent to each other, so that the parasitic resistance and parasitic inductance of the wiring in the switched capacitor circuit 20 can be reduced. Therefore, the switched capacitor circuit 20 can supply a plurality of highly accurate and stable discrete voltages to the output switch circuit 30, so that the power supply voltage V ET This can suppress deterioration of the output waveform.

[0184] Also, for example, in the tracker module 100, the capacitor may be a capacitor to which the highest potential is applied among a plurality of capacitors included in the switched capacitor circuit 20.

[0185] This reduces the parasitic resistance and parasitic inductance of the wiring that maximizes the amount of charge transfer. ET This effectively prevents the output waveform from deteriorating.

[0186] For example, in the tracker module 100, the switched capacitor circuit 20 may include two of the above-mentioned capacitors, and when the module substrate 90 is viewed in a plane, the integrated circuit 80 may have a rectangular outer peripheral shape, with one of the two capacitors adjacent to an edge 801 of the integrated circuit 80, and the other of the two capacitors adjacent to an edge 802 different from the edge 801 of the integrated circuit 80.

[0187] This allows the wires connected to the two capacitors to be shortened while dispersing and dissipating heat generated from these two wires, thereby improving the heat dissipation performance of the tracker module 100.

[0188] For example, in the tracker module 100, the switched capacitor circuit 20 includes a plurality of the above-mentioned capacitors, the plurality of capacitors including a pair of capacitors C13 and C16 that complementarily charge and discharge, and a capacitor C10 that smoothes the voltages of the capacitors C13 and C16, and when the module substrate 90 is viewed in a plane, the integrated circuit 80 has a rectangular outer periphery, and each of the capacitors C13, C16 and C10 may be adjacent to an edge 802 that forms the periphery of the integrated circuit 80.

[0189] This allows the wiring connecting the capacitors C13, C10, and C16 to be short, thereby reducing the parasitic resistance and parasitic inductance of the wiring. Therefore, the switched capacitor circuit 20 can supply a plurality of highly accurate and stable second voltages to the output switch circuit 30.

[0190] Furthermore, for example, in tracker module 100, when module substrate 90 is viewed from above, capacitor C10 may be disposed between capacitor C13 and capacitor C16.

[0191] According to this, since the smoothing capacitor is disposed between the pair of flying capacitors, the interaction of heat generated from the capacitors C13 and C16 can be reduced, and heat dissipation is effectively improved and characteristic degradation is suppressed.

[0192] For example, the tracker module 100 may include a capacitor included in a pre-regulator circuit 10 configured to convert an input voltage to a first voltage using a power inductor and output the first voltage to a switched capacitor circuit 20, the integrated circuit 80 may include a switch included in the pre-regulator circuit 10, and the integrated circuit 80 and the capacitor of the pre-regulator circuit 10 may be adjacent to each other.

[0193] According to this, since the integrated circuit 80 and the capacitor of the pre-regulator circuit 10 are adjacent to each other, the wiring connecting the capacitor and the switch of the PR switch section 10A can be shortened, and the parasitic resistance and parasitic inductance of the wiring in the pre-regulator circuit 10 can be reduced. Therefore, the pre-regulator circuit 10 can supply a highly accurate and stable first voltage to the switched capacitor circuit 20.

[0194] Also, for example, the tracker module 100 may include circuit components included in the filter circuit 40 to which at least one of the plurality of discrete voltages is input, and the integrated circuit 80 and the circuit components may be adjacent to each other.

[0195] According to this, by arranging the integrated circuit 80 and the circuit components of the filter circuit 40 adjacent to each other, the wiring connecting the circuit components and the switches of the OS switch section 30A can be shortened, thereby reducing the parasitic resistance and parasitic inductance of the wiring connecting the filter circuit 40 and the output switch circuit 30.

[0196] Moreover, the tracker module 100 according to this embodiment includes a module substrate 90, a first circuit, and a second circuit. The first circuit has a capacitor C12 having a first electrode and a second electrode, a capacitor C15 having a third electrode and a fourth electrode, and switches S21, S32, S22, S31, S23, S34, S24, and S33, one end of the switch S21 and one end of the switch S22 are connected to the first electrode, one end of the switch S32 and one end of the switch S31 are connected to the second electrode, one end of the switch S23 and one end of the switch S24 are connected to the third electrode, one end of the switch S34 and one end of the switch S33 are connected to the fourth electrode, the other end of the switch S21, the other end of the switch S32, the other end of the switch S23, and the other end of the switch S34 are connected to each other, the other end of the switch S22 is connected to the other end of the switch S24, and the other end of the switch S31 is connected to the other end of the switch S33. The second circuit has a switch S53 connected between the output terminal 130, the other end of the switch S21, the other end of the switch S32, the other end of the switch S23, and the other end of the switch S34, and the output terminal 130, and a switch S52 connected between the other ends of the switches S22 and S24 and the output terminal 130. The switches S21, S22, S23, S24, S31, S32, S33, S34, S52, and S53 are included in an integrated circuit 80, and the capacitor C12, the capacitor C15, and the integrated circuit 80 are disposed on a module substrate 90, and the integrated circuit 80 is adjacent to one of the capacitors C12 and C15.

[0197] According to the above configuration, the integrated circuit 80 and one of the capacitors C12 and C15 are adjacent to each other, so that the wiring connecting the capacitor and the switch of the first circuit can be shortened, and the parasitic resistance and parasitic inductance of the wiring in the first circuit can be reduced. Therefore, a plurality of highly accurate and stable second voltages can be supplied from the first circuit to the second circuit, so that the power supply voltage V output from the tracker module 100 can be reduced. ET This can suppress deterioration of the output waveform.

[0198] Also, for example, in tracker module 100, capacitors C12 and C15 may be capacitors to which the highest potential is applied among the multiple capacitors included in the first circuit.

[0199] This reduces the parasitic resistance and parasitic inductance of the wiring that maximizes the amount of charge transfer. ET This effectively prevents the output waveform from deteriorating.

[0200] For example, in tracker module 100, the first circuit may include a plurality of capacitors including capacitors C12 and C15, and when module substrate 90 is viewed in a plan view, integrated circuit 80 may have a rectangular outer peripheral shape, one of capacitors C12 and C15 may be adjacent to a first edge that constitutes the outer periphery of integrated circuit 80, and one of the plurality of capacitors other than the one may be adjacent to a second edge that is different from the first edge.

[0201] This allows the wires connected to the two capacitors to be shortened while dispersing and dissipating heat generated from these two wires, thereby improving the heat dissipation performance of the tracker module 100.

[0202] For example, in tracker module 100, the first circuit includes capacitor C13 having first and second electrodes, capacitor C16 having third and fourth electrodes, and further capacitor C10 having fifth and sixth electrodes, the fifth electrode being connected to the other end of switch S31, the other end of switch S42, the other end of switch S33, and the other end of switch S44, and the sixth electrode being connected to the other end of switch S41 and the other end of switch S43, and when module substrate 90 is viewed in a plane, integrated circuit 80 has a rectangular outer periphery, and each of capacitors C13, C16, and C10 may be adjacent to a first side that constitutes the periphery of integrated circuit 80.

[0203] Furthermore, for example, in tracker module 100, when module substrate 90 is viewed from above, capacitor C10 may be disposed between capacitor C13 and capacitor C16.

[0204] For example, the tracker module 100 further includes a third circuit having an input terminal 110, a switch S71 connected between the input terminal 110 and one end of a power inductor L71, a switch S72 connected between one end of the power inductor L71 and ground, a switch S63 connected between the other end of the power inductor L71, the other end of the switch S21, the other end of the switch S32, the other end of the switch S23, and the other end of the switch S34, and a capacitor C63 connected between one end of the switch S63 and ground, wherein the switches S63, S71, and S72 are included in an integrated circuit 80, the capacitor C63 is disposed on a module substrate 90, and the integrated circuit 80 and the capacitor C63 may be adjacent to each other.

[0205] According to this, since the integrated circuit 80 and the capacitor C63 are adjacent to each other, the wiring connecting the capacitor and the switch of the third circuit can be shortened, and the parasitic resistance and parasitic inductance of the wiring in the third circuit can be reduced. Therefore, the third circuit can supply the first voltage with high accuracy and stability to the second circuit.

[0206] For example, the tracker module 100 further includes a fourth circuit connected to the output terminal 130, the fourth circuit constituting an LC filter including circuit components which are any of an inductor, a capacitor and a resistive element, the circuit components being disposed on the module substrate 90, and the integrated circuit 80 and the circuit components being adjacent to each other.

[0207] The communication device 7 according to the present embodiment includes an RFIC 5 for processing high-frequency signals, a power amplifier circuit 2 for transmitting high-frequency signals between the RFIC 5 and an antenna 6, and a power supply voltage V ET and a tracker module 100 that provides:

[0208] This allows the communication device 7 to achieve the same effects as those of the tracker module 100 described above.
