[0002] Please refer to Figure 1 In existing technologies, the transmit and receive functions of the n77 and n78 bands typically require two independent discrete components: the n77 and n78 LPAMIF LNAs (low-noise amplifiers) and the n77 and n78 RX LFEMs (low-frequency front-end modules for the n77 and n78 band receivers). Because these are separate components, the RF front-end layout occupies a large area, and the number and area of shielding enclosures increase accordingly. Specifically, the TX / PRX / DRX paths of the n77 and n78 bands rely on the n77 and n78 LPAMIF LNAs for transmit and receive functions; while the PRX MIMO / DRX MIMO paths of the n77 and n78 bands require the n77 and n78 RX LFEMs for receive. This traditional architecture results in complex RF circuit structures, large PCB footprints, numerous shielding enclosures, and high hardware costs, while also increasing the difficulty of PCB layout and routing design.

[0008] Furthermore, after the main receiver signal and the main MIMO receiver signal are received by the antenna module, before being switched to the LNA BANK via the first switching switch set in Phase 5NPA, the method further includes: The main set received signal and the main set MIMO received signal are switched to the SAW filter by the second switching switch for signal processing, and then input into the Phase 5N PA.
[0009] Furthermore, the main received signal is the n77 band main received signal and the n78 band main received signal; The main receiver signal of the n77 band and the main receiver signal of the n78 band are received via the n77 and n78 transceiver terminals of the first switching switch. The signal is switched to the n77 and n78 main receiver terminals of the LNA BANK via the first switching switch. After signal processing by the LNA BANK, the signal is input to the RF transceiver via the intermediate frequency main receiver output terminal of the LNA BANK. The intermediate frequency master signal output terminal is also used to input the intermediate frequency master signal into the radio frequency transceiver.
[0010] Furthermore, the main MIMO received signal is the n77 band main MIMO received signal and the n78 band main MIMO received signal; The n77 band primary MIMO received signal and the n78 band primary MIMO received signal are received via the n77 and n78 transceiver terminals of the first switching switch, switched to the n77 and n78 primary MIMO signal receiving terminals of the LNA BANK via the first switching switch, and after signal processing by the LNA BANK, input to the RF transceiver via the n77 and n78 primary MIMO signal output terminals of the LNA BANK.
[0011] Furthermore, the LNA BANK includes a first LNA and a second LNA; the n77 and n78 master signal receivers are located in the first LNA, and the n77 and n78 master MIMO signal receivers are located in the second LNA. The main receiver signal of the n77 band and the main receiver signal of the n78 band are input into the first LNA via the n77 and n78 main receiver terminals for low-noise amplification.

Detailed Implementation
[0016] The following description, in conjunction with schematic diagrams, illustrates a 5G communication method and communication circuit according to the present invention, which represents a preferred embodiment of the invention. It should be understood that those skilled in the art can modify the invention described herein while still achieving its advantageous effects. Therefore, the following description should be understood as being of general knowledge to those skilled in the art and is not intended to limit the invention.
[0017] The invention is described more specifically by way of example in the following paragraphs with reference to the accompanying drawings. The advantages and features of the invention will become clearer from the following description. It should be noted that the drawings are in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of the invention.
[0018] Example 1 Please refer to Figure 2 and Figure 4 This embodiment discloses a 5G communication method, the method comprising: The transmitted signal is generated by the radio frequency transceiver, processed by the Phase 5N PA, and then transmitted through the antenna module.
[0019] The main receiver signal and the main MIMO receiver signal are received by the antenna module and switched to the LNA BANK (Low Noise Amplifier Bank) by the first switching switch 1 set in the Phase 5N PA (5G NR High Frequency Power Amplifier Module). After signal processing by the LNA BANK, the signal is input to the radio frequency transceiver.
[0020] The diversity reception signal and the diversity MIMO reception signal are received by the antenna module, processed by the DRX Difem (diversity reception front-end module), and then input into the radio frequency transceiver.
[0021] The transmitted signal, the main MIMO received signal, the main received signal, the diversity received signal, and the diversity MIMO received signal all include radio frequency signals in the n77 band and radio frequency signals in the n78 band.
[0022] In this embodiment, the n77 and n78 band transmitted signals, after being amplified by the Phase 5N PA, are routed to the antenna module via the second switching switch 2 for signal transmission. This ensures that the processing of the n77 and n78 band transmitted signals is completed entirely within the Phase 5N PA, eliminating the need for separate n77 and n78 L-PAMIF devices. The main received signals and main MIMO received signals of the n77 and n78 bands are received by the antenna module and routed to the LNA BANK by the first switching switch 1 within the Phase 5N PA for signal processing before being sent to the RF transceiver, eliminating the need for separate n77 and n78 LNA devices. The diversity received signals and diversity MIMO received signals of the n77 and n78 bands are received by the antenna module and then routed to the DRX. After signal processing by the Difem, the signal is directly sent to the RF transceiver, eliminating the need for separate n77 and n78 RX LFEM devices. This signal transmission process allows all transceiver paths in the n77 and n78 bands to be processed without additional discrete RF components, effectively reducing the number of RF devices, shrinking the PCB layout area and the number of shielding covers, optimizing the front-end insertion loss of the n77 and n78 bands, and lowering hardware costs.
[0023] In this embodiment, before the transmitted signal is processed by the Phase 5N PA and input into the antenna module for signal transmission, the method further includes: the transmitted signal is switched to the antenna module for signal transmission via the second switching switch 2.
[0024] Please continue to refer to this. Figure 3 and Figure 5 In this embodiment, Figure 3 Region A in Figure 5 The communication circuits shown are the same.
[0025] In this embodiment, the transmitted signals are n77 band transmitted signals and n78 band transmitted signals.
[0026] The n77 band transmission signal and the n78 band transmission signal are input to the Phase 5N PA through the high-frequency signal receiving terminal HB_TX of the Phase 5N PA for signal processing, and are output by the n77 and n78 transceiver terminals MH3 of the first switching switch 1.
[0027] In this embodiment, the n77 band transmission signal and the n78 band transmission signal are input to the Phase 5NPA via the high-frequency signal receiving terminal HB_TX for signal processing, including: The n77 band transmission signal and the n78 band transmission signal are amplified by the power amplifier 3 installed in the Phase 5N PA.
[0028] In this embodiment, the high-frequency signal receiver HB_TX, originally used to receive transmitted signals from other NR high-frequency bands (such as the n41 band) besides the n77 and n78 bands, now has its operating frequency range extended to cover the n77 and n78 bands. This port is reused to simultaneously receive and process transmitted signals from the n77 and n78 bands. By multiplexing the high-frequency signal receiver HB_TX, there is no need to add separate input ports for the n77 and n78 band transmitted signals, nor is it necessary to configure independent n77 and n78 L-PAMIF devices outside the Phase 5NPA. Power amplification of the n77 and n78 band transmitted signals can be completed within the Phase 5N PA, effectively simplifying the RF circuit design, reducing external matching networks and PCB layout traces, and saving PCB placement area and hardware costs.
[0029] It is understandable that the Phase 5N PA can process signals including but not limited to n77 and n78 band transmission signals, as well as other nR high-frequency band transmission signals such as n40 and n41, to meet the overall requirements of 5G multi-band communication.
[0030] Please refer to Figure 3 and Figure 6 In this embodiment, Figure 3 Region B in Figure 6 The communication circuits shown are the same.
[0031] In this embodiment, after the main receiver signal and the main MIMO receiver signal are received by the antenna module, they are switched to the LNA BANK via the first switching switch 1 set in the Phase5N PA. The method further includes: The master received signal and the master MIMO received signal are switched to SAW filter 4 (bulk acoustic wave filter) by the second switching switch 2 for signal processing, and then input into the Phase 5N PA.
[0032] In this embodiment, by switching to SAW filter 4 via the second switching switch 2 before the main set received signal and the main set MIMO received signal enter Phase 5N PA, the out-of-band spurious and interference signals can be effectively filtered out, the frequency selectivity and purity of the signal can be improved, and the out-of-band noise entering Phase 5N PA can be reduced.
[0033] Furthermore, in this embodiment, the second switching switch 2 can support the n77 and n78 frequency bands. That is, the operating frequency of the second switching switch 2 covers the entire frequency range of the n77 band (3300MHz~4200MHz) and the n78 band (3300MHz~3800MHz). By selecting a switching switch that supports the above-mentioned wide frequency band range, the signal integrity of the n77 band main receiver signal, the n78 band main receiver signal, the n77 band main MIMO receiver signal, and the n78 band main MIMO receiver signal during the switching process is effectively guaranteed, meeting the requirements of multi-band broadband switching and laying the foundation for high-quality signal processing of the subsequent receiving link.
[0034] Furthermore, in this embodiment, the main received signal is the n77 band main received signal and the n78 band main received signal.
[0035] The main receiver signals of the n77 band and the n78 band are received via the n77 and n78 transceiver terminals MH3 of the first switching switch 1. They are then switched to the n77 and n78 main receiver signal receiving terminal MHB1_SW3 of the LNA BANK via the first switching switch 1. After signal processing by the LNA BANK, the signals are input to the RF transceiver via the intermediate frequency main receiver signal output terminal MHB PRX of the LNA BANK.
[0036] The intermediate frequency master signal output terminal MHB PRX is also used to input the intermediate frequency master signal into the radio frequency transceiver.
[0037] In this embodiment, the intermediate frequency master signal output terminal MHB PRX, originally used to output the intermediate frequency band master received signal processed by the LNA BANK to the RF transceiver, is now reused to simultaneously output the n77 band master received signal and the n78 band master received signal after low noise amplification by the first LNA to the RF transceiver. There is no need to add new dedicated n77 and n78 band signal output ports. By reusing the existing intermediate frequency master signal output terminal MHB PRX of the LNA BANK, the number of device pins and PCB interconnections is effectively reduced while meeting the signal transmission quality of each frequency band, further saving PCB layout area.
[0038] In this embodiment, the intermediate frequency (IF) master signal is the IF band master reception signal originally carried by the LNA BANK, such as B3 (1800MHz band), B1 (2100MHz band), or n41 (2500MHz band), etc., which are mid-to-high frequency band master reception signals. Those skilled in the art can reasonably select the specific frequency band signal output by the IF master signal output terminal MHB PRX according to the frequency band combination and RF architecture requirements supported by the actual product, and no limitation is made here.
[0039] In this embodiment, the n77 band main receiver signal, the n78 band main receiver signal, and the intermediate frequency main receiver signal share the same intermediate frequency main receiver signal output terminal MHB PRX of the LNA BANK to be input to the RF transceiver. There is no need to add separate output interfaces for the n77 band main receiver signal and the n78 band main receiver signal. The existing output ports of the LNA BANK are fully utilized. While meeting the transmission quality of signals in each frequency band, the number of device pins and PCB interconnections is reduced, and the layout design of the RF circuit is simplified.
[0040] Furthermore, in this embodiment, the master MIMO received signal is the n77 band master MIMO received signal and the n78 band master MIMO received signal.
[0041] The n77 band primary MIMO received signal and the n78 band primary MIMO received signal are received via the n77 and n78 transceiver terminals MH3 of the first switching switch 1, switched to the n77 and n78 primary MIMO signal receiving terminal MHB2_SW1 of the LNA BANK via the first switching switch 1, and after signal processing by the LNA BANK, input to the RF transceiver via the n77 and n78 primary MIMO signal output terminals of the LNA BANK.
[0042] In this embodiment, the n77 band main MIMO received signal and the n78 band main MIMO received signal are uniformly amplified for low noise by the LNA BANK, eliminating the need for separate n77 and n78 RX LFEM devices, reducing independent RF paths, and effectively reducing front-end insertion loss; at the same time, integrating the n77 band and n78 band MIMO receive paths into the LNA BANK further reduces the PCB layout area and the number of shielding covers, saving hardware costs.
[0043] Furthermore, in this embodiment, the method further includes: The LNA BANK includes a first LNA5 (low noise amplifier) and a second LNA6; the n77 and n78 master signal receivers MHB1_SW3 are located in the first LNA5, and the n77 and n78 master MIMO signal receivers MHB2_SW1 are located in the second LNA6.
[0044] The main receiver signal of the n77 band and the main receiver signal of the n78 band are input to the first LNA5 via the n77 and n78 main receiver signal receivers MHB1_SW3 for low-noise amplification.
[0045] The n77 band primary MIMO received signal and the n78 band primary MIMO received signal are input to the second LNA6 via the n77 and n78 primary MIMO signal receiving terminals MHB2_SW1 for low-noise amplification.
[0046] Among them, the first LNA5 and the second LNA6 are LNAs inherent in the LNA BANK, and there is no need to add additional discrete LNA devices outside the LNA BANK. While realizing the low noise amplification function of the n77 and n78 frequency bands, it reuses the existing hardware resources inside the LNA BANK, avoiding the additional PCB layout area occupation, increased shielding requirements and hardware cost caused by adding discrete devices.
[0047] The LNA BANK can also transmit main receiver signals and main MIMO receiver signals in the mid-frequency band (such as B1, B3, etc.) and other NR high-frequency bands (such as n41, etc.). Those skilled in the art can make reasonable configurations according to the frequency band combinations and RF architecture requirements supported by the actual product, and this application does not impose any restrictions on this.
[0048] Please refer to Figure 3 and Figure 7 In this embodiment, Figure 3 Region C in Figure 7 The communication circuits shown have the same structure.
[0049] The diversity received signals are the n77 band diversity received signal and the n78 band diversity received signal; the diversity MIMO received signals are the n77 band diversity MIMO received signal and the n78 band diversity MIMO received signal.
[0050] The n77 band diversity reception signal and the n78 band diversity reception signal are input into the DRX Difem through the mid-to-high frequency diversity signal receiving terminal LNA_OUT_MHB1 of the DRX Difem for signal processing.
[0051] The n77 band diversity MIMO received signal and the n78 band diversity MIMO received signal are input into the DRX Difem through the diversity MIMO signal receiver LNA_OUT_MHB2 of the DRX Difem for signal processing.
[0052] In this embodiment, the mid-to-high frequency diversity signal receiver LNA_OUT_MHB1, originally used to receive diversity reception signals other than the n77 and n78 frequency bands (such as DRX signals in the B3, B1, and n41 frequency bands), now has its operating frequency range extended to cover the n77 and n78 frequency bands; the diversity MIMO signal receiver LNA_OUT_MHB2, originally used to receive diversity MIMO reception signals other than the n77 and n78 frequency bands (such as DRX signals in the B3, B1, and n41 frequency bands), now has its operating frequency range extended to cover the n77 and n78 frequency bands.
[0053] In this embodiment, the aforementioned receiver is reused to simultaneously carry the inputs of the n77 and n78 band diversity reception signals and the n77 and n78 band diversity MIMO reception signals. This allows the n77 and n78 DRX paths to share the same receiver with the original DRX paths. It also allows the n77 and n78 DRX MIMO paths to share the same receiver with the original DRX MIMO paths. There is no need to add separate input ports for the n77 and n78 band diversity reception signals and the n77 and n78 band diversity MIMO reception signals, effectively saving the pin resources and external connections of the DRXDifem.
[0054] It is understood that the DRX Difem can also transmit other mid-to-high frequency band diversity reception signals and diversity MIMO reception signals (such as DRX and DRX MIMO signals in the B3, B1, and n41 bands) in addition to the n77 and n78 bands. Those skilled in the art can make reasonable configurations according to the frequency band combinations and RF architecture requirements supported by the actual product, and this application does not impose any restrictions on this.
[0055] For further details, please refer to... Figure 3 The HB / MB / LB transmit signals are respectively driven by the driver amplifier and then enter the Phase2N PA power amplifier. The signals of each frequency band (B1 / B3 / B5 / B8 / B40 / B41 / B26A, etc.) are amplified and filtered and matched before being fed into the TX_ module (TRX1~TRX15) on the right. After power detection by the built-in CPL coupler, they are finally transmitted from the antenna.

[0057] Specifically, the communication circuit includes: Phase 5N PA is used to process the transmitted signal and transmit the transmitted signal into the antenna module for signal transmission.
[0058] The LNA BANK is used to process the main received signal and the main MIMO received signal, and input the main received signal and the main MIMO received signal into the radio frequency transceiver.
[0059] The DRX Difm is used to process the diversity received signal and the diversity MIMO received signal, and input the diversity received signal and the diversity MIMO received signal into the radio frequency transceiver.
[0060] The transmitted signal, the main MIMO received signal, the main received signal, the diversity received signal, and the diversity MIMO received signal all include radio frequency signals in the n77 band and radio frequency signals in the n78 band.
[0061] In this embodiment, the Phase 5N PA, the LNA BANK, and the DRX Difem are all equipped with ports for transmitting RF signals in the n77 and n78 bands, or the original transmission ports in the Phase 5N PA, the LNA BANK, and the DRX Difem can be reused. This allows for signal processing of all transmit and receive paths in the n77 and n78 bands without the need for additional dedicated RF devices or extra pins. This effectively reduces the number of RF front-end devices, shrinks the PCB layout area, reduces front-end link insertion loss, saves hardware costs, and improves overall RF communication performance.
