These terms are only used to distinguish the first element from another element, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, the features defined as "first" and "second" can explicitly or implicitly include at least one of the features. In the description of this application, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0032] It should be noted that when an element is referred to as being "disposed on" another element, it may be directly on the other element or there may be an intermediate element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be an intermediate element at the same time.

[0033] At present, RF devices that support the multi-band communication needs of 5G ultra-high frequency bands are mainly provided by overseas manufacturers. These manufacturers usually integrate and bundle out-of-band high-suppression filters with power amplifiers, low-noise amplifiers, etc. and then sell them at high prices. The high selling price of RF devices has greatly increased the RF front-end costs of domestic communication equipment manufacturers. At the same time, the integrated bundling of such filters with power amplifiers, low-noise amplifiers, etc. has also hindered domestic RF device manufacturers from participating in the preparation of such RF devices.

Specifically, the first transmitting port and the second transmitting port can be used to connect with the RF transceiver respectively to transmit the first UHF band signal and the second UHF band signal from the RF transceiver to the inside of the power amplifier module 10, so that the power amplifier module 10 supports two-way transmission; the multiple first receiving ports and the multiple second receiving ports are used to connect with the RF transceiver respectively to transmit the first UHF band signal and the second UHF band signal received by the power amplifier module 10 in multiple channels to the RF transceiver, so that the power amplifier module 10 supports multi-way reception; the multiple antenna ports are used to connect with the antenna to transmit the RF signal between the antenna and the power amplifier module 10.

[0039] The first switch module 100 has multiple first ends and multiple second ends, and the multiple first ends of the first switch module 100 are respectively connected to the multiple antenna ports; the first power amplifier module 200 is respectively connected to the first transmitting port and a second end of the first switch module 100, and is used to amplify the first ultra-high frequency band signal received by the first transmitting port; the second power amplifier module 300 is respectively connected to the second transmitting port and the other second end of the first switch module 100, and is used to amplify the second ultra-high frequency band signal received by the second transmitting port; multiple first receiving modules 400 are respectively connected to the multiple first receiving ports and part of the second ends of the first switch module 100, and the multiple first receiving modules 400 are used to support multi-channel reception of the first ultra-high frequency band signal; multiple second receiving modules 500 are respectively connected to the multiple second receiving ports and another part of the second end of the first switch module 100, and the multiple second receiving modules 500 are used to support multi-channel reception of the second ultra-high frequency band signal.

[0040] Among them, the first switch module 100 is respectively connected to multiple antenna ports, the first power amplifier module 200, the second power amplifier module 300, the multiple first receiving modules 400, and the multiple second receiving modules 500. The first switch module 100 can respectively select to conduct the RF path between the first power amplifier module 200, the second power amplifier module 300, the multiple first receiving modules 400, the multiple second receiving modules 500 and any antenna port, so that the power amplifier module 10 supports two-way transmission and multi-channel reception to realize the transmission control and reception control of different signals. Optionally, based on the number of antenna ports, the number of amplifier modules, and the number of receiving modules, the first switch module 100 can select one or more multi-channel selection switches to realize the gating function of the RF path between the first power amplifier module 200, the second power amplifier module 300, the multiple first receiving modules 400, the multiple second receiving modules 500 and any antenna port.

[0041] Among them, the first power amplifier module 200 and the second power amplifier module 300 are respectively used to perform power amplification processing on the first ultra-high frequency band signal and the second ultra-high frequency band signal to be transmitted, so that the power amplifier module 10 supports two-way transmission processing of the first ultra-high frequency band signal and the second ultra-high frequency band signal. Further, the first power amplifier module 200 and the second power amplifier module 300 respectively include a power amplifier (Power amplifier, PA), each power amplifier is connected to the RF transceiver through a transmitting port to receive the signal to be transmitted from the RF transceiver, and is connected to the antenna port through the first switch module 100 to transmit the signal to be transmitted after power amplification through the antenna port.

[0042] Among them, the first receiving module 400 and the second receiving module 500 are respectively used to perform power amplification processing on the received first ultra-high frequency band signal and the second ultra-high frequency band signal, so that the power amplifier module 10 supports multi-channel receiving processing of the first ultra-high frequency band signal and the second ultra-high frequency band signal. Further, the first receiving module 400 and the second receiving module 500 respectively include a low noise amplifier (Low Noise Amplifier, LNA), each low noise amplifier is connected to the antenna port through the first switch module 100 to receive the signal to be received from the antenna, and is connected to the RF transceiver through the receiving port to transmit the signal to be received after the low noise amplification processing to the RF transceiver through the receiving port.

[0043] Among them, the first ultra-high frequency band signal and the second ultra-high frequency band signal are ultra-high frequency band signals of different frequency bands in the 5G RF signal. Optionally, the first ultra-high frequency band signal is an N77 / N78 band signal, and the second ultra-high frequency band signal is an N79 band signal. Therefore, the power amplifier module 10 is a multi-frequency multi-mode amplifier module that can support N77 / N78 and N79, and can also be understood as an L-PAM module (LNA and PA Module, a module integrating LNA, PA and switch).

[0044] In the related art, among the RF devices supporting the multi-band communication requirements of the 5G ultra-high frequency band, taking the N77 and N79 dual-band RF devices as examples, the N77 transmission channel is composed of an N77 power amplifier and an N77 transmission filter, the N79 transmission channel is composed of an N79 power amplifier and an N79 transmission filter, each N77 receiving channel is composed of a low noise amplifier and an N77 receiving filter, and each N79 receiving channel is composed of a low noise amplifier and an N79 receiving filter. That is, the RF devices supporting the multi-band communication requirements of the 5G ultra-high frequency band in the related art usually integrate and bind the filter with the power amplifier, the low noise amplifier, etc. to form an L-PAMiF (LNA and PA Module integrated with Filter, a module integrating LNA, PA, filter and switch) RF device, which is expensive, greatly increasing the RF front-end cost of domestic communication equipment manufacturers, and at the same time, the integrated binding method of the filter with the power amplifier, the low noise amplifier, etc. also hinders domestic RF device manufacturers from participating in the preparation of the RF device, resulting in a passive situation for domestic RF front-end devices.

[0045] The power amplifier module 10 provided in this embodiment is configured with a first transmitting port, a second transmitting port, a plurality of first receiving ports, a plurality of second receiving ports and a plurality of antenna ports for connecting to an antenna. The power amplifier module 10 includes a first switch module 100, a first power amplifier module 200, a plurality of first receiving modules 400 and a plurality of second receiving modules 500, so that the power amplifier module 10 can support the transmission and multi-channel reception of the first ultra-high frequency band signal, the transmission and multi-channel reception of the second ultra-high frequency band, and realize the multi-band communication requirements. Therefore, the power amplifier module 10 can realize the multi-band communication requirements of the 5G ultra-high frequency band on the basis of realizing the decoupling of the power amplifier, the low-noise amplifier and the filter, greatly reducing the cost of the RF front-end; at the same time, the current technical fields of power amplifiers, low-noise amplifiers, switches, etc. in China are already very mature, and the aforementioned decoupling method is conducive to giving play to the technical advantages of domestic manufacturers in power amplifiers, low-noise amplifiers and other devices, so that more manufacturers can participate in the preparation of the power amplifier module 10, greatly promoting the development of domestic RF front-end devices and improving the passive situation of domestic RF front-end devices.

[0046] In one embodiment, if Figure 2 As shown, the multiple antenna ports include multiple first antenna ports and multiple second antenna ports ( Figure 2 In the figure, two first receiving modules 400 and two second receiving modules 500 are taken as an example, and the first antenna port supports the transmission and reception of N77 radio frequency signals, and the second antenna port supports the transmission and reception of N79 radio frequency signals.

[0048] Among them, the first switch unit 110 is respectively connected to multiple first antenna ports, the first power amplifier module 200 and the multiple first receiving modules 400. The first switch unit 110 can choose to conduct the radio frequency path between the first power amplifier module 200 and any first antenna port to support the first ultra-high frequency band signal to be transmitted alternately between the multiple first antenna ports, thereby supporting the sounding reference signal (SRS) function of the first ultra-high frequency band; the first switch unit 110 can also choose to conduct the radio frequency path between each first receiving module 400 and a first antenna port, so that the multiple first receiving modules 400 support multi-channel reception processing of the first ultra-high frequency band signal. Optionally, the first switch unit 110 can be an nPnT switch. For example, the first switch unit 110 can be a 3P4T switch. In the embodiment of the present application, n can be adjusted and set according to the number of the multiple first antenna ports and the number of the multiple first receiving modules 400, and no further limitation is made here.

[0049] The second switch unit 120 has multiple first ends and multiple second ends. The multiple first ends of the second switch unit 120 are respectively connected to the multiple second antenna ports, and some of the second ends of the second switch unit 120 are respectively connected to the output end of the second power amplifier module 300 and the input ends of the multiple second receiving modules 500; the second switch unit 120 is used to select and conduct the radio frequency path between the second power amplifier module 300 and any second antenna port, so that the second power amplifier module 300 supports the alternating transmission of the second ultra-high frequency band signal between the multiple second antenna ports; the second switch unit 120 is also used to select and conduct the radio frequency path between each second receiving module 500 and a second antenna port, so that each second receiving module 500 receives the second ultra-high frequency band signal from the second antenna port.

[0050] Among them, the second switch unit 120 is respectively connected to multiple second antenna ports, the second power amplifier module 300 and multiple second receiving modules 500, and the second switch unit 120 can choose to conduct the radio frequency path between the second power amplifier module 300 and any second antenna port to support the second ultra-high frequency band signal to be transmitted alternately between multiple second antenna ports, thereby supporting the sounding reference signal (SRS) function of the second ultra-high frequency band; the second switch unit 120 can also choose to conduct the radio frequency path between each second receiving module 500 and a second antenna port, so that multiple second receiving modules 500 support multi-channel reception processing of the second ultra-high frequency band signal. Optionally, the second switch unit 120 can be an mPmT switch. Exemplarily, the second switch unit 120 can be a 3P3T switch. In the embodiment of the present application, m can be adjusted and set according to the number of multiple second antenna ports and the number of multiple second receiving modules 500, and no further limitation is made here.

[0051] This embodiment sets a first switch unit 110 corresponding to the first power amplification module 200, multiple first receiving modules 400, and multiple first antenna ports, and a second switch unit 120 corresponding to the second power amplification module 300, multiple second receiving modules 500, and multiple second antenna ports, so as to independently control the transmission channel of each ultra-high frequency band signal, the conduction state of the connection between multiple receiving channels and the target antenna port, and more accurately switch the antenna port and the RF channel.

[0052] In one embodiment, if Figure 3 As shown, the power amplifier module 10 is also configured with a first-round transmit input port (such as SRS-In1 in the figure), which is connected to the other second end of the first switch unit 110. The first-round transmit input port is used to connect to an external third power amplifier module to receive a third ultra-high frequency band signal after amplification by the third power amplifier module. The frequency band of the third ultra-high frequency band signal is the same as the frequency band of the first ultra-high frequency band signal.

[0053] Among them, the first round of transmission input port is respectively connected to the first switch unit 110 and the external third power amplifier module to receive the third ultra-high frequency band signal after amplification and processing by the third power amplifier module, so that the power amplifier module 10 can further realize two-way transmission of the first ultra-high frequency band signal and the third ultra-high frequency band signal and multi-channel reception of the first ultra-high frequency band signal, further improving the RF transmission performance of the power amplifier module 10.

[0054] Furthermore, the first switch unit 110 is also connected to the first round transmitting port, and the first switch unit 110 is also used to select the RF path between the first round transmitting input port and any first antenna port, so that the first round transmitting input port supports the alternating transmission of the third ultra-high frequency band signal between multiple first antenna ports, further optimizing the SRS function of the power amplifier module 10 to support the first ultra-high frequency band signal and the third ultra-high frequency band signal.

[0055] The first switch unit 110 of this embodiment is respectively connected to the first round emitting port, the first power amplifier module 200, multiple first receiving modules 400 and multiple first antenna ports. The gating function of the first switch unit 110 realizes the multi-channel SRS function of the first ultra-high frequency band signal and the third ultra-high frequency band signal of the power amplifier module 10, the multi-channel receiving function of the first ultra-high frequency band signal and the channel switching control function, thereby improving the RF performance of the power amplifier module 10; at the same time, each first antenna port can be switchably connected to different modules and ports, thereby further improving the utilization rate of each first antenna port, which is beneficial to reducing costs and improving the integration of devices.

[0056] For example, the number of the first receiving module 400 and the number of the second receiving module 500 are two, respectively; the plurality of first antenna ports include two first rotating antenna ports and two first non-rotating antenna ports (please continue to refer to Figure 3 , Figure 3 Taking this as an example, in the figure, N77 SRS-out1 and N77 SRS-out2 are two first round-radiating antenna ports respectively, and N77ANT0 and N77 ANT1 are two first non-round-radiating antenna ports respectively). Each first round-radiating antenna port can be switchably connected to the first power amplifier module 200 and the first round-radiating input port, and each first non-round-radiating antenna port can be switchably connected to the first power amplifier module 200, the first round-radiating input port and a first receiving module 400.

[0057] The first round-radiation antenna port can be understood as an antenna port for supporting the transmission of the first UHF band signal and the third UHF band signal. The antenna port is switchably connected to the first power amplifier module 200 and the first round-radiation input port to realize the SRS function of the first UHF band signal and the third UHF band signal; the first non-round-radiation antenna port can be understood as an antenna port for supporting the transmission and reception of the first UHF band signal and the third UHF band signal. The antenna port is switchably connected to the first power amplifier module 200, the first round-radiation input port and a first receiving module 400 to realize the transmission of the first UHF band signal and the third UHF band signal and the reception of the first UHF band signal. Therefore, the first round-radiation antenna port and the first non-round-radiation antenna port can be switchably connected to different modules and ports, thereby improving the utilization of the first round-radiation antenna port and the first non-round-radiation antenna port, reducing costs and improving the integration of devices.

[0058] In one embodiment, if Figure 4 As shown, the power amplifier module 10 is also configured with a second round of transmit input port (such as SRS-In2 in the figure), which is connected to the other second end of the second switch unit 120. The second round of transmit input port is used to connect to an external fourth power amplifier module to receive a fourth ultra-high frequency band signal after amplification by the fourth power amplifier module. The frequency band of the fourth ultra-high frequency band signal is the same as the frequency band of the second ultra-high frequency band signal.

[0059] Among them, the second round of transmission input port is respectively connected to the second switch unit 120 and the external fourth power amplifier module to receive the fourth ultra-high frequency band signal after amplification and processing by the fourth power amplifier module, so that the power amplifier module 10 can further realize two-way transmission of the second ultra-high frequency band signal and the fourth ultra-high frequency band signal and multi-channel reception of the second ultra-high frequency band signal, further improving the RF transmission performance of the power amplifier module 10.

[0060] Furthermore, the second switch unit 120 is also connected to the second transmitting port, and the second switch unit 120 is also used to select the RF path between the second transmitting input port and any second antenna port, so that the second transmitting input port supports the fourth ultra-high frequency band signal to be transmitted alternately between multiple second antenna ports, further optimizing the SRS function of the power amplifier module 10 to support the second ultra-high frequency band and the fourth ultra-high frequency band signals.

[0061] The second switch unit 120 of this embodiment is respectively connected to the second round transmitting port, the second power amplifier module 300, multiple second receiving modules 500 and multiple second antenna ports. The selection function of the second switch unit 120 realizes the multi-channel SRS function of the second ultra-high frequency band signal and the fourth ultra-high frequency band signal of the power amplifier module 10, the multi-channel receiving function of the second ultra-high frequency band signal and the channel switching control function, thereby improving the RF performance of the power amplifier module 10; at the same time, each second antenna port can be switchably connected to different modules and ports, further improving the utilization rate of each second antenna port, which is beneficial to reducing costs and improving the integration of devices.

[0062] For example, the number of the first receiving module 400 and the number of the second receiving module 500 are two respectively; the plurality of second antenna ports include a second round-robin antenna port and two second non-round-robin antenna ports (please continue to refer to Figure 4 , Figure 4 Taking this as an example, in the figure, N79 SRS-out is the second round-radiating antenna port, N79 ANT0 and N79 ANT1 are two second non-round-radiating antenna ports respectively), each second round-radiating antenna port can be switchably connected to the second power amplifier module 300 and the second round-radiating input port, and each second non-round-radiating antenna port can be switchably connected to the second power amplifier module 300, the second round-radiating input port and a second receiving module 500.

[0063] The second round-radiation antenna port can be understood as an antenna port for supporting the transmission of the second UHF band signal, and the antenna port is switchably connected to the second power amplifier module 300 and the second round-radiation input port to realize the SRS function of the second UHF band signal and the fourth UHF band signal; the second non-round-radiation antenna port can be understood as an antenna port for supporting the transmission and reception of the second UHF band signal and the fourth UHF band signal, and the antenna port is switchably connected to the second power amplifier module 300, the second round-radiation input port and a second receiving module 500 to realize the transmission of the second UHF band signal and the fourth UHF band signal and the reception of the second UHF band signal. Therefore, the second round-radiation antenna port and the second non-round-radiation antenna port can be switchably connected to different modules and ports, thereby improving the utilization of the second round-radiation antenna port and the second non-round-radiation antenna port, reducing costs and improving the integration of devices.

[0064] In one embodiment, if Figure 4As shown, the power amplifier module 10 is also configured with an auxiliary input port (such as LAA In in the figure), which is used to connect to an external auxiliary receiving module to receive a radio frequency signal received by the external auxiliary receiving module. The radio frequency signal can be a first ultra-high frequency band signal and / or a second ultra-high frequency band signal, or other radio frequency signals other than the above two signals, thereby enabling the power amplifier module 10 to add a receiving processing function and improve the radio frequency receiving performance.

[0065] Further, based on the fact that the power amplifier module 10 is also configured with an auxiliary input port, please continue to refer to Figure 4 The power amplifier module 10 also includes: a second switch module 600.

[0066] The second switch module 600, the first end of the second switch module 600 is connected to the target receiving port, and the multiple second ends of the second switch module 600 are respectively connected to the auxiliary input port and the target receiving module. The second switch module 600 is used to conduct the connection between the target receiving module and the target receiving port, or to conduct the connection between the auxiliary input port and the target receiving port.

[0067] The target receiving port may be the first receiving port and / or the second receiving port to realize multiplexing of the first receiving port or the second receiving port, improve the effective utilization of the port and the integration of the port, and reduce the cost. Optionally, the target receiving port is the first receiving port, and the target receiving module is the first receiving module 400; and / or the target receiving port is the second receiving port, and the target receiving module is the second receiving module 500 (this is used as an example in the figure).

[0068] Among them, the second switch module 600 is respectively connected to the target receiving port, the auxiliary input port, and the target receiving module. The second switch module 600 can choose to conduct the connection between the target receiving module and the target receiving port, so that the target receiving port transmits the first ultra-high frequency band signal or the second ultra-high frequency band signal received and processed by the target receiving module, or conducts the connection between the auxiliary input port and the target receiving port, so that the target receiving port receives the RF signal from the external auxiliary receiving module. Optionally, the second switch module 600 can be an SPnT switch. For example, the target receiving port is the first receiving port, the target receiving module is the first receiving module 400, and the second switch module 600 can be an SP2T switch. In the embodiment of the present application, n can be adjusted according to the number of target receiving ports, and no further limitation is made here.

[0069] In this embodiment, by setting a second switch module 600 corresponding to the target receiving port, the auxiliary input port, and the target receiving module, the target receiving module and the external auxiliary receiving module can reuse the same receiving port, thereby improving the effective utilization rate of the port and the integration of the port, and reducing the cost; at the same time, when the target receiving port is used to connect to a receiving port of the RF transceiver, the multiplexing of the target receiving port also improves the effective utilization rate of the receiving port of the RF transceiver and the integration of the port of the RF transceiver, and reduces the cost of the RF transceiver.

[0070] In one embodiment, if Figure 5 As shown, the power amplifier module 10 further includes: a first coupling module 700 and a second coupling module 800 .

[0071] The first coupling module 700 is arranged on the transmission channel between the first power amplifier module 200 and the first switch module 100, and is used to couple the first ultra-high frequency band signal after being amplified and processed by the first power amplifier module 200 to obtain a first coupled signal; the second coupling module 800 is arranged on the transmission channel between the second power amplifier module 300 and the first switch module 100, and is used to couple the second ultra-high frequency band signal after being amplified and processed by the second power amplifier module 300 to obtain a second coupled signal.

[0072] Specifically, the first coupling module 700 includes an input end, an output end and a coupling end. The input end of the first coupling module 700 is connected to the first power amplification module 200, the output end of the first coupling module 700 is connected to a second end of the first switch module 100, and the coupling end of the first coupling module 700 is used to couple the first ultra-high frequency band signal received at the input end and output the first coupled signal; the second coupling module 800 includes an input end, an output end and a coupling end. The input end of the second coupling module 800 is connected to the second power amplification module 300, the output end of the second coupling module 800 is connected to a second end of the first switch module 100, and the coupling end of the second coupling module 800 is used to couple the second ultra-high frequency band signal received at the input end and output the second coupled signal.

[0073] The first coupling signal may include a first forward coupling signal and a first reverse coupling signal, and the second coupling signal may include a second forward coupling signal and a second reverse coupling signal, the first forward coupling signal and the second forward coupling signal respectively correspond to the forward coupling powers for measuring the first ultra-high frequency band signal and the second ultra-high frequency band signal; the first reverse coupling signal and the second reverse coupling signal respectively correspond to the reverse coupling powers for measuring the first ultra-high frequency band signal and the second ultra-high frequency band signal.

[0074] The power amplifier module 10 is further configured with a coupling output port (such as CPL-OUT in the figure), which can be switchably connected to the first coupling module 700 and the second coupling module 800, and the coupling output port is used to connect to the RF transceiver to transmit the received first coupling signal or the second coupling signal to the RF transceiver, thereby, the RF transceiver can perform the related detection functions of the forward coupling power and the reverse coupling power of the two RF signals according to the first coupling signal or the second coupling signal transmitted by the coupling output port, thereby realizing the adjustment of the output power of the first power amplifier module 200 and the second power amplifier module 300. It can be understood that the coupling output port can be connected to the first coupling module 700 and the second coupling module 800 respectively through the switch module, so as to realize the switchable connection between the first coupling module 700 and the second coupling module 800 through the on-off state of the switch module.

[0075] In this embodiment, by providing the first coupling module 700, the second coupling module 800 and the coupling output port switchably connected to the two coupling modules, on the one hand, the RF transceiver can receive any one of the first coupling signal and the second coupling signal, and realize the related detection function of the forward coupling power and the reverse coupling power of the two RF signals; on the other hand, the effective utilization rate of the coupling output port and the integration of the port can be improved, and the cost can be reduced; at the same time, the multiplexing of the coupling output port also improves the effective utilization rate of a power detection port of the RF transceiver and the integration of the port of the RF transceiver, and reduces the cost of the RF transceiver.

[0076] In one of the embodiments, please refer to Figure 5 The power amplifier module 10 is also configured with an auxiliary coupling input port (such as CPL-IN in the figure), and the auxiliary coupling input port is used to connect to an external third coupling module to receive a third coupling signal obtained by the third coupling module.

[0077] Among them, the third coupling module can couple the target RF signal to obtain a third coupling signal, and the target RF signal can be at least one of the first ultra-high frequency band signal and the second ultra-high frequency band signal, or other RF signals. The third coupling signal can include a third forward coupling signal and a third reverse coupling signal, and the third forward coupling signal and the third reverse coupling signal correspond to the forward coupling power and the reverse coupling power used to measure the target RF signal, respectively, so that the RF transceiver can realize the relevant power detection function and adjust the output power of the power amplifier module connected to the external third coupling module.

[0078] Further, based on the above embodiments, please continue to refer to Figure 5 The power amplifier module 10 also includes: a third switch module 900.

[0079] The first end of the third switch module 900 is connected to the coupling output port, and the three second ends of the third switch module 900 are respectively connected to the first coupling module 700, the second coupling module 800, and the auxiliary coupling input port. The third switch module 900 is used to select and conduct the connection between the target coupling module and the coupling output port. The target coupling module includes any one of the first coupling module 700, the second coupling module 800 and the third coupling module.

[0080] The third switch module 900 is respectively connected to the coupling end of the first coupling module 700, the coupling end of the second coupling module 800, the auxiliary coupling input port and the coupling output port, and is used to selectively output the coupling signal to the coupling output port or input the third coupling signal of the external third coupling module from the coupling input port. It can be understood that when the power amplifier module 10 is applied to the radio frequency system, if a plurality of radio frequency devices are provided in the radio frequency system, the distance between the plurality of radio frequency devices is usually small, while the distance between the radio frequency devices and the radio frequency transceiver is large. Therefore, an auxiliary coupling input port in this embodiment can obtain the third coupling signal of the external third coupling module and transmit it, thereby realizing the transfer of the radio frequency signal through the power amplifier module 10, thereby reducing the number of wirings between the external third coupling module and the radio frequency transceiver, and realizing the same coupling signal transmission function with a smaller number of wirings, so as to further improve the integration of the radio frequency system.

[0081] In this embodiment, the power amplifier module 10 is only provided with one coupled output port. Since the RF signals of multiple frequency bands are not transmitted simultaneously, one coupled output port can also meet the communication requirements, improve the effective utilization rate of the port, and reduce the complexity of the RF routing inside the power amplifier module 10. At the same time, it can also improve the isolation performance of each routing of the power amplifier module 10.

[0082] In one embodiment, the power amplifier module 10 is further configured with a power port, which is respectively connected to the power supply end of the first power amplifier module 200 and the power supply end of the second power amplifier module 300, and the power port is used to connect to an external power supply so that the power supply supplies power to the first power amplifier module 200 and the second power amplifier module 300. In this embodiment, the normal operation of the first power amplifier module 200 and the second power amplifier module 300 can be ensured by setting the power port, thereby ensuring the stability and reliability of the overall operation of the power amplifier module 10.

[0083] In one embodiment, based on any of the above embodiments, Figure 6 As shown, the radio frequency device also includes: a filtering module 1000 ( Figure 6 by Figure 5 The examples are used as an example).

[0084] The filter module 1000 has multiple first ends connected to the multiple second ends of the first switch module 100, and the multiple second ends of the filter module 1000 are connected to the multiple antenna ports. The filter module 1000 is used to filter the received first ultra-high frequency band signal and the second ultra-high frequency band signal.

[0085] Among them, the filtering module 1000 is connected to the first switch module 100 and multiple antenna ports respectively. The filtering module 1000 can be used to filter the first ultra-high frequency band signal and the second ultra-high frequency band signal to be transmitted output by each power amplification module, and output them to each antenna port; the filtering module 1000 can also be used to filter the first ultra-high frequency band signal and the second ultra-high frequency band signal received by each antenna port, and output them to each receiving module.

[0086] Optionally, the filtering module 1000 may include multiple independent filters, and the transmitting filter and the receiving filter are respectively located on each transmitting channel and each receiving channel to independently filter the RF signal to be transmitted and the RF signal received by the antenna port.

[0087] Optionally, the filter module 1000 may also include a plurality of duplexers or multiplexers, each targeting a target frequency band, and the plurality of first ends of each duplexer or multiplexer are respectively connected to the power amplifier module and the receiving module through the second end of the first switch module 100, and the second end of each duplexer or multiplexer is connected to the antenna port. The filter module 1000 can not only filter the RF signal amplified and processed by each power amplifier module to output the RF signal after power amplification and filtering to the antenna port, but also filter the RF signal received by the antenna port, and the RF signal after filtering is then amplified and processed by each receiving module and output to the receiving port. Thus, the filter module 1000 has the filtering processing function of both the transmitting and receiving processes, and can improve the isolation effect of the transceiver path and the output power of the transceiver path.

[0088] It can be understood that after decoupling each power amplifier module, each receiving module and the filter module 1000 in any of the above embodiments is achieved, it is not only conducive to reducing the cost of the RF front-end and improving the passive situation of domestic RF front-end devices, but also, when the filter module 1000 needs to be set, the setting position, selection specifications, device type, etc. of the filter module 1000 can be made more flexible and variable. For example, when the filter module 1000 is set to filter the first ultra-high frequency band signal and the second ultra-high frequency band signal, the filter module 1000 can be set on the antenna port side inside the power amplifier module 10 (as shown in the above embodiment), or it can be set outside the power amplifier module 10; at the same time, the non-binding integration of the filter allows each manufacturer to select filters of different specifications according to the needs of their respective products, making the design of the power amplifier module 10 more flexible and adaptable to more communication scenarios. For example, products with low coexistence requirements can use ordinary LTCC filters with low out-of-band suppression to reduce costs while adapting to product requirements. In the binding integration method in the related art, the position of the filter is limited, and the specifications of the filter are often fixed to high-suppression filters. When the high-suppression filters are applied to products with low coexistence requirements, not only is the cost high, but it also causes a waste of filtering resources.

[0089] It can be understood that in order to realize the transmission and reception control of any of the above embodiments, Figure 7As shown, the power amplifier module 10 may further include a first control module 1100 and a second control module 1200. The first control module 1100 may be connected to each switch unit and each power amplifier module, for example, the first switch unit 110, the second switch unit 120, the first power amplifier module 200, and the second power amplifier module 300, respectively, to control the on and off of each switch unit, and also to control the working state of each power amplifier module, so as to achieve the transmission control of the power amplifier module 10. The second control module 1200 may be connected to each switch unit and each receiving module, and to adjust the working state and gain coefficient of each receiving module, thereby adjusting the link loss of each receiving channel, thereby improving the sensitivity of each receiving channel, so as to achieve the reception control of the power amplifier module 10. Among them, the first control module 1100 and the second control module 1200 can be a mobile industry processor interface (MIPI)-RF front end control interface (RFFE) control module, or a RF front end control interface (RFFE) control module, which complies with the control protocol of the RFFE bus. When the first control module 1100 and the second control module 1200 are MIPI-RFFE control modules or RFFE control modules, the power amplifier module 10 can also be configured with a clock signal input pin CLK, a single / bidirectional data signal input or bidirectional pin SDATAS, a power pin VDD, a reference voltage pin VIO, etc., to achieve control of the first power amplifier module 200, the second power amplifier module 300, multiple first receiving modules 400, multiple second receiving modules 500 and each switch module.

[0090] The following is based on Figure 7 The power amplifier module 10 shown in the figure takes the first UHF band signal and the third UHF band signal as N77, and the second UHF band signal and the fourth UHF band signal as N79 as an example, and specifically analyzes the working principle of the N77&N79 1T2R LPAM module in this embodiment (wherein 1T2R refers to the one-way transmission and two-way receiving function of the LPAM module to amplify the RF signal). In the N77&N79 1T2R LPAM module, the first power amplifier includes N77PA, the second power amplifier includes N79PA, the two first receiving modules 400 include N77 LNA1 and N77 LNA2 respectively, the two second receiving modules 500 include N79LNA1 and N79 LNA2 respectively, and the other modules and ports are respectively as shown in FIG. Figure 7 As shown (the power port is not shown in the figure), it will not be repeated here.

[0091] The transmission process of the N77 RF signal: the N77 RF signal to be transmitted output by the RF transceiver enters the LPAM module through the first transmission port Tx In1, is amplified by the N77 power amplifier, and then the amplified N77 signal enters the 4P4T RF switch through the first coupling module 700, and conducts the connection between the N77 power amplifier and any of the first non-rotating antenna port N77ANT0, the first non-rotating antenna port N77 ANT1, the first rotating antenna port N77 SRS-out1, and the first rotating antenna port N77SRS-out2, so as to transmit the N77 RF signal through the antenna port and the antenna connected thereto, and realize the rotation of the N77 RF signal between multiple antennas. Among them, the first coupling module 700 can sample the N77 RF signal passing through, and the first coupled signal obtained by sampling enters the SP3T switch, and is connected to the coupling output port CPL-OUT through the SP3T switch, so as to transmit the first coupled signal to the RF transceiver for analysis and processing.

[0093] The receiving process of the N77 RF signal: the first non-radiating antenna port N77 ANT0 port transmits the N77 RF signal received from the antenna to the conductively connected low noise amplifier N77 LNA1 for signal amplification and then outputs it from the first receiving port N77RX out11 to be transmitted to the RF transceiver.

[0094] Another N77 RF signal receiving process: the first non-radiating antenna port N77 ANT1 port transmits the N77 RF signal received from the antenna to the conductively connected low noise amplifier N77 LNA2 for signal amplification and then outputs it from the first receiving port N77 RX out112 to be transmitted to the RF transceiver.

[0095] The transmission process of the N79 RF signal: the N79 RF signal to be transmitted output by the RF transceiver enters the LPAM module through the second transmission port Tx In1, is amplified by the N79 power amplifier, and then the amplified N79 signal enters the 3P4T RF switch through the second coupling module 800, and conducts the connection between the N79 power amplifier and any of the second non-rotating antenna port N79ANT0, the second non-rotating antenna port N79 ANT1, and the second rotating antenna port N79 SRS-out, so as to transmit the N79 RF signal through the antenna port and the antenna connected thereto, and realize the rotation of the N79 RF signal between multiple antennas. Among them, the second coupling module 800 can sample the N79 RF signal passing through, and the second coupled signal obtained by sampling enters the SP3T switch, and is connected to the coupling output port CPL-OUT through the SP3T switch, so as to transmit the second coupled signal to the RF transceiver for analysis and processing.

[0096] The transmission process of another N79 RF signal: the N79 RF signal amplified by the fourth power amplifier module enters the 3P4T RF switch through the second round-robin input port SRS-In2, and the connection between the second round-robin input port SRS-In2 and any one of the second non-round-robin antenna port N79 ANT0, the second non-round-robin antenna port N79 ANT1, and the second round-robin antenna port N79 SRS-out is turned on, so as to transmit another N79 RF signal through the antenna port and the antenna connected to it, and realize the round-robin of the N79 RF signal between multiple antennas.

[0097] The receiving process of N79 RF signal: The second non-rotating antenna port N79 ANT0 port transmits the N79 RF signal received from the antenna to the low noise amplifier N79 LNA1 for signal amplification, and then connects to the second receiving port N79 RX out21 output through the SPDT switch to transmit to the RF transceiver.

[0098] Another N79 RF signal receiving process: The second non-radiating antenna port N79 ANT1 port transmits the N79 RF signal received from the antenna to the conductively connected low noise amplifier N79 LNA2 for signal amplification and then outputs it from the second receiving port N79 RX out22 to be transmitted to the RF transceiver.
