[0037] The RF PA Mid device involved in the embodiments of the present application can be applied to communication devices with wireless communication functions, and the communication devices can be handheld devices, vehicle-mounted devices, wearable devices, computer devices or other processing devices connected to a wireless modem, as well as various forms of user equipment (UE), such as mobile phones, mobile stations (MS); and network devices, such as base stations, access points, etc.

[0038] In order to cope with the increasing demands for various communication standards and solve the problem of tight layout of printed circuit boards (PCBs), high integration and miniaturization of radio frequency devices have become a development trend.

[0039] For example, in the related technology, the initial RF front-end second-phase (Phase2) product can support a single frequency band (Single Band); subsequently, based on the miniaturization development trend of the terminal device motherboard, the seventh-phase enhanced version (Phase7 Lite Enhancement, Phase7LE) product was defined that can support the integration of various communication standards, thereby making the integration of RF devices higher and higher.

[0040] Figure 1 A schematic diagram of the structure of a radio frequency system Figure 1 .like Figure 1 As shown, the radio frequency system may include a radio frequency transceiver 110, a low frequency (Low Band, LB) PA Mid module 120, a medium high frequency (Medium High Band, MHB) PA Mid module 130, a fifth generation mobile communication technology (5th Generation Mobile Communication Technology, 5G) PA Mid module (i.e., an ultra-high frequency PA Mid module) 140 and an antenna group 150; wherein:

[0041] The RF transceiver 110 may include a transmitter (Transmitter, TX), or may include a receiver (Receiver, RX), or may include a transmitter and a receiver. The RF transceiver 110 may be used to implement frequency conversion processing between RF signals and baseband signals, and / or to implement frequency conversion processing of signals in different frequency bands, etc.

[0042] The RF PA Mid module (such as the LB PA Mid module 120, the MHB PA Mid module 130, and the 5G PA Mid module 140) can be used to support the amplification, transceiver and control of RF signals. In other words, the RF PA Mid module can realize the reception and transmission control of a single RF signal.

[0043] Exemplarily, the RF PA Mid module may be a packaged chip, and is configured with a receiving path for receiving RF signals and a transmitting path for transmitting RF signals, so as to achieve control over the reception and transmission of RF signals.

[0044] like Figure 1As shown, the LB PA Mid module 120 can support 2G / 3G / 4G signals in the low frequency band. One end (i.e., RX1) of the LB PA Mid module 120 is connected to the first end of the RF transceiver 110, and the other end (i.e., ANT1) is connected to the antenna Ant1, so as to realize the transceiver control of the low frequency signal. For example, the LB PA Mid module 120 can realize the transceiver control of the low frequency signal in one or more frequency bands of the N5 frequency band, the N8 frequency band, the N20 frequency band, and the N28 frequency band.

[0045] The MHB PA Mid module 130 can support 2G signals in the high frequency band and 3G / 4G signals in the medium and high frequency band. One end (i.e., RX2) of the MHB PA Mid module 130 is connected to the second end of the RF transceiver 110, and the other end (i.e., ANT2) is connected to the antenna Ant2, thereby realizing the transceiver control of the medium and high frequency signals. For example, the MHB PA Mid module 130 can realize the transceiver control of the medium and high frequency signals in the N41 frequency band.

[0046] The 5G PA Mid module 140 can support 5G signals in the UHF band. One end (ie, RX3) of the 5G PA Mid module 140 is connected to the third end of the RF transceiver 110, and the other end (ie, ANT3) is connected to the antenna Ant3, thereby realizing the transceiver control of the UHF signal. For example, the 5G PA Mid module 140 can realize the transceiver control of the UHF signal in the N77 band and / or the N79 band.

[0047] The antenna group 150 may include antenna Ant1, antenna Ant2 and antenna Ant3. Antenna Ant1 can support 2G / 3G / 4G signals in low frequency bands, for example, antenna Ant1 can be used to receive and transmit low frequency signals in one or more frequency bands of N5 band, N8 band, N20 band and N28 band; antenna Ant2 can support 2G signals in high frequency bands and 3G / 4G signals in medium and high frequency bands, for example, antenna Ant2 can be used to receive and transmit medium and high frequency signals in N41 band; antenna Ant3 can support 5G signals in ultra-high frequency bands, for example, antenna Ant3 can be used to receive and transmit ultra-high frequency signals in N77 band and / or N79 band.

[0048] In some embodiments, each antenna in the antenna group 150 (such as antenna Ant1, antenna Ant2, and antenna Ant3) may be a directional antenna or a non-directional antenna.

[0049] Exemplarily, each antenna in the antenna group 150 may be formed using any suitable type of antenna. For example, each antenna in the antenna group 150 may include an antenna having a resonant element formed by the following antenna structures: an array antenna structure, a loop antenna structure, a patch antenna structure, a slot antenna structure, a helical antenna structure, a strip antenna, a monopole antenna, a dipole antenna, or one or more thereof. Different types of antennas may be used for frequency band combinations of different radio frequency signals.

[0050] The entire chip architecture of the LB PA Mid module and the MHB PA Mid module integrates multi-band transmit and receive channels. Figure 2 and Figure 3 The components and structures of the LB PA Mid module and the MHB PA Mid module are described respectively.

[0051] Figure 2 FIG. 1 is a schematic diagram of the structure of a LB PA Mid module. Figure 2 As shown, the LB PA Mid module may include a power amplifier (such as 4G LB PA), a switch (such as DPDT#2), a coupler, a low-noise amplifier (Low-NoiseAmplifier, LNA), and a controller (such as PA+ASM RFFE1, and also such as LNA RFFE2); wherein:

[0052] The power amplifier can be used to amplify a radio frequency signal (such as a low frequency signal) to increase the power of the radio frequency signal.

[0053] A switch can be used to connect and disconnect a circuit, thereby controlling the connection or disconnection of the circuit.

[0054] The coupler can be used to couple the low frequency signal in the radio frequency path and output the low frequency signal through the coupled output port.

[0055] A low noise amplifier is an amplifier with a very low noise factor. A low noise amplifier can improve the signal-to-noise ratio of the output low-frequency signal by reducing the noise of the amplifier itself.

[0056] The controller can be used for at least one of the following: controlling the on and off of each switch, controlling the working state of each power amplifier, and adjusting the gain coefficient of each low noise amplifier.

[0057] Figure 3 Figure 1 is a schematic diagram of the structure of a MHB PA Mid module. Figure 3As shown, the MHB PA Mid module may include a power amplifier (such as MB 4G PA), a switch (such as DP7T), a coupler, a low noise amplifier (such as LNA1), and a controller (such as PA+ASM RFFE1 and LNA RFFE2). The functions of each device are similar to Figure 2 The functions of the corresponding devices are similar and will not be described again here.

[0058] In the embodiments of the present application, the Phase7LE products and related devices can be combined to construct a framework for radio frequency applications. Figure 4 A schematic diagram of the structure of a radio frequency system Figure 2 .like Figure 4 As shown, the RF system may include a RF transceiver, an LBPA Mid module, an MHB PA Mid module, a 5G PA Mid module and an antenna group (such as Ant1 to Ant6). The corresponding functions of each device can refer to the relevant description in the aforementioned embodiments and will not be repeated here.

[0059] In addition, the radio frequency system may further include a combiner (such as Combiner 1), a filter (such as a triple saw filter), a 4G LFEM module, a 5G LFEM1 module, a 5G LFEM2 module, and a 5G LFEM3 module; wherein:

[0060] A combiner is a device that combines input signals in an RF circuit to produce a single output signal. How a combiner works depends on its type. For example, a coaxial combiner works by using common-mode rejection.

[0061] The filter can be used to filter radio frequency signals (such as medium and high frequency signals and ultra-high frequency signals).

[0062] The LFEM module can be understood as a low noise amplifier front-end module (Low Noise AmPlifier–Front-End Modules). The LFEM module can be used to support dual-channel reception of RF signals of two or more frequency bands, and can also be used to support the transmission of RF signals.

[0063] Based on Figure 4 The radio frequency system shown in FIG. 1 can realize the control of receiving and sending radio frequency signals. Figure 4 As shown, taking the N79 frequency band as an example, the working principle is as follows:

[0101] The received signal enters the RF transceiver through the SDR DRX14 port.

[0102] With the development and progress of technology, the demand for various communication standards (such as 4G signals and 5G signals) is also increasing. Due to the low integration of RF devices such as PA Mid (such as LB PA Mid module, MHB PA Mid module, and 5G PA Mid module), the design cost of the RF structure is high and the area occupied by the substrate is large.

[0103] Based on this, an embodiment of the present application provides a radio frequency PA Mid device, which may include a low frequency PA Mid module, a medium and high frequency PA Mid module, an ultra high frequency PA Mid module and a 2G high frequency power amplifier, wherein: one end of the transmission path of the low frequency PA Mid module, the medium and high frequency PA Mid module and the ultra high frequency PA Mid module is electrically connected to the input end, and the other end is electrically connected to the antenna end; one end of the receiving path of the low frequency PA Mid module, the medium and high frequency PA Mid module and the ultra high frequency PA Mid module is electrically connected to the receiving end, and the other end is electrically connected to the output end; one end of the 2G high frequency power amplifier is electrically connected to the medium and high frequency input end, and the other end is electrically connected to the medium and high frequency transmission path. In this way, the low frequency PA Mid module, the medium and high frequency PA Mid module, the ultra high frequency PA Mid module and the 2G high frequency power amplifier are integrated in the radio frequency PA Mid device, which can improve the integration of the radio frequency PAMid device, reduce the design cost of the radio frequency structure, and reduce the area occupied by the substrate.

[0104] The embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0105] Figure 5 A schematic diagram of the composition structure of a radio frequency PA Mid device provided in an embodiment of the present application Figure 1 .like Figure 5 As shown, the RF PA Mid device is configured with one or more low-frequency input ports (such as LBRFIN) and output ports (such as OUT1), one or more medium-high frequency input ports (such as MHB RFIN) and output ports (such as OUT2), one or more ultra-high frequency input ports (such as UHB RFIN) and output ports (such as OUT3) for connecting to the RF transceiver, and one or more low-frequency receiving ports (such as AUX1), one or more medium-high frequency receiving ports (such as AUX2), one or more ultra-high frequency receiving ports (such as AUX3), and one or more antenna ports (such as ANT1 to ANT3) for connecting to the antenna; the RF PA Mid device includes:

[0106] A low-frequency PA Mid module 501, the low-frequency PA Mid module 501 includes a first low-frequency transmitting path 502 and a low-frequency receiving path 503, one end of the first low-frequency transmitting path 502 is configured to be electrically connected to one or more low-frequency input ports (such as LB RFIN), and the other end is configured to be electrically connected to one or more antenna ports (such as ANT1), one end of the low-frequency receiving path 503 is configured to be electrically connected to one or more low-frequency receiving ports (such as AUX1), and the other end is configured to be electrically connected to one or more low-frequency output ports (such as OUT1);

[0107] A mid-high frequency PA Mid module 504, the mid-high frequency PA Mid module 504 comprises a first mid-high frequency transmitting path 505 and a first mid-high frequency receiving path 506, one end of the first mid-high frequency transmitting path 505 is configured to be electrically connected to one or more mid-high frequency input ports (such as MHB RFIN), and the other end is configured to be electrically connected to one or more antenna ports (such as ANT2), one end of the first mid-high frequency receiving path 506 is configured to be electrically connected to one or more mid-high frequency receiving ports (such as AUX2), and the other end is configured to be electrically connected to one or more mid-high frequency output ports (such as OUT2);

[0108] The UHF PA Mid module 507 includes a first UHF transmitting path 508 and a first UHF receiving path 509. One end of the first UHF transmitting path 508 is configured to be electrically connected to one or more UHF input ports (such as UHB RFIN), and the other end is configured to be electrically connected to one or more antenna ports (such as ANT3). One end of the first UHF receiving path 509 is configured to be electrically connected to one or more UHF receiving ports (such as AUX3), and the other end is configured to be electrically connected to one or more UHF output ports (such as OUT3).

[0109] 2G high frequency power amplifier 510 , one end of which is configured to be electrically connected to one or more medium and high frequency input ports (such as 2G HB IN), and the other end of which is configured to be electrically connected to the first medium and high frequency transmission path 505 .

[0110] In some embodiments, the low-frequency PA Mid module 501 can be used to process low-frequency signals in one or more frequency bands of the N5 frequency band, the N8 frequency band, the N20 frequency band, and the N28 frequency band; the medium- and high-frequency PA Mid module 504 is used to process medium- and high-frequency signals in the N41 frequency band; and the ultra-high-frequency PA Mid module 507 is used to process ultra-high-frequency signals in the N77 frequency band and / or the N79 frequency band.

[0112] In the related art, multiple devices in the RF PA Mid device need to be powered and controlled by the Mobile Industry Processor Interface (MIPI), which increases the complexity of PCB layout and wiring. For example, the 2G high-frequency power amplifier is deployed in the low-frequency PA Mid module, and the output end of the 2G high-frequency power amplifier is connected to one end of the medium- and high-frequency PAMid module, thereby increasing the link loss and reducing the performance of the 2G high-frequency power amplifier.
