Fig. 1 is a schematic diagram of a multi-mode rf circuit according to an embodiment of the present application. The multi-mode radio frequency circuit comprises a transceiver 10, a first signal path, a second signal path and a third signal path, wherein the first signal path, the second signal path and the third signal path are respectively electrically connected with the transceiver 10; wherein, as shown in fig. 1:

the first signal path includes an MHB (Middle High Band) radio frequency module 1101, a first antenna 1102 and a second antenna 1103; the first rf module 1101 is electrically connected to the first antenna 1102 and the second antenna 1103 respectively; when the multi-mode radio frequency circuit is in the first mode, the transceiver 10 is electrically connected to the first signal path, and the transceiver 10 transmits or receives the first signal through the first signal path.

The second signal path includes an MMPA (multi mode and multi band Power Amplifier) rf module 1201, a first antenna 1102 and a second antenna 1103; the second rf module 1201 is electrically connected to the first antenna 1102 and the second antenna 1103, respectively; when the multi-mode radio frequency circuit is in the second mode, the transceiver 10 is electrically connected to the second signal path, and the transceiver 10 transmits or receives the first signal through the second signal path.

The third signal path includes the first rf module 1101, the third antenna 1301, and the fourth antenna 1302; the first rf module 1101 is electrically connected to the third antenna 1301 and the fourth antenna 1302 respectively; when the multi-mode radio frequency circuit is in the second mode, the transceiver 10 is electrically connected to a third signal path through which the transceiver 10 transmits or receives a second signal.

In one embodiment, the first mode is an LTE (Long Term Evolution) mode, and the second mode is an LTE and NR (New Radio) dual-connected ENDC mode. The first signal is an LTE signal and the second signal is an NR signal. Based on this, the first signal path is turned on when the multi-mode radio frequency circuit is in the LTE mode, and the second signal path and the third signal path are turned on when the multi-mode radio frequency circuit is in the endec mode.

When the multi-mode radio frequency circuit is in the LTE mode, a first signal sent by the transceiver 10 is transmitted to the first antenna 1102 and the second antenna 1103 through the first signal path, and a first signal received by the first antenna 1102 and the second antenna 1103 is also transmitted to the transceiver 10 through the first signal path.

When the multi-mode rf circuit is in the endec mode, a first signal from the transceiver 10 is transmitted through the second signal path to the first antenna 1102 and the second antenna 1103, and a second signal from the transceiver 10 is transmitted through the third signal path to the third antenna 1301 and the fourth antenna 1302.

Furthermore, based on the compatibility of the multi-mode radio frequency circuit, research and development personnel do not need to design the radio frequency circuit respectively according to the equipment under different mode requirements, and therefore the research and development cost, the model loss, the manpower loss and other problems of the radio frequency circuit are reduced.

In one embodiment, the multi-mode radio frequency circuit further comprises a first switching module and a second switching module. A first end of the first rf module 1101 is electrically connected to an input end of the first switching module, a first output end of the first switching module is electrically connected to a first input end of the second switching module, the second rf module 1201 is electrically connected to a second input end of the second switching module, a first output end of the second switching module is electrically connected to the first antenna 1102, a second output end of the second switching module is electrically connected to the second antenna 1103, and a second output end of the first switching module is electrically connected to the third antenna 1301 and the fourth antenna 1302 through the third switching module.

The second output end of the first switching module and the second diversity receiving module are electrically connected to the third antenna 1301 and the fourth antenna 1302 through the third switching module, respectively, and the fifth antenna is electrically connected to the main diversity receiving module. The first mode is a one-path transmitting two-path receiving mode, and the second mode is a two-path transmitting four-path receiving mode.

When the multi-mode rf circuit is in the first mode, the first antenna 1102 and the second antenna 1103 receive a first signal, the main set portion of the first signal is transmitted to the transceiver 10 through the first rf module 1101, and the diversity portion is transmitted to the transceiver 10 through the first diversity receive module.

When the multi-mode rf circuit is in the second mode, the first antenna 1102 receives the dominant set portion of the first signal and transmits the dominant set portion to the transceiver 10 through the second rf module 1201; the second antenna 1103 receives the diversity portion of the first signal and transmits it to the transceiver 10 via the first diversity receive module. The second antenna 1103 receives the diversity portion of the second signal and transmits the diversity portion to the transceiver 10 through the first diversity receiving module; the third antenna 1301 receives the main set part in the second signal and transmits the main set part to the transceiver 10 through the first radio frequency module 1101; the fourth antenna 1302 and the fifth antenna receive the MIMO signal in the second signal and transmit to the transceiver 10 through the second diversity receiving module and the main set receiving module, respectively.

In this embodiment, when a MIMO (Multiple-Input Multiple-Output) signal includes a diversity part and a main set part, the fourth antenna 1302 receives the diversity part of the MIMO signal and transmits the MIMO signal to the transceiver 10 through the second diversity receiving module; the fifth antenna receives the main set portion of the MIMO signal and transmits to the transceiver 10 through the main set receiving module.

In one embodiment, the LTE signal comprises an LTE mid/high band signal and the NR signal comprises an NR mid/high band signal. The first diversity receiving module and the second diversity receiving module are medium/high frequency diversity receiving modules; the master set receiving module is a medium/high frequency master set receiving module.

The low frequency rf module transmits a first low frequency band signal to the first antenna 1102 and the second antenna 1103, and transmits a main set portion of the first low frequency band signal received by the first antenna 1102 to the transceiver 10, and the low frequency diversity receiving module transmits a diversity portion of the first low frequency band signal received by the second antenna 1103 to the transceiver 10.

In this embodiment, when the multi-mode rf circuit is in the second mode and the first signal is an LTE mid/high band signal, the LTE mid/high band signal is transmitted to the transceiver 10 through the second signal path. When the first signal is an LTE low-band signal, the LTE low-band signal is transmitted to the transceiver 10 through the low-frequency power amplifier module LB PAMID and the low-frequency diversity receiving module LB DRx.

It can be seen that by utilizing the existing architecture of the multi-mode radio frequency circuit, the transmission of multiple frequency band signals or combined signals in the first and second modes can be achieved. Through signal path switching and multiplexing of the antenna in the multi-mode radio frequency circuit, the radio frequency circuit architecture has compatibility under multiple modes, and circuit architectures do not need to be designed respectively aiming at different modes, so that the research and development cost of the radio frequency circuit is reduced.

In any of the above embodiments, the first switch module may be a SPDT, the second switch module may be a DP4T, and the third switch module may be a DPDT. The first signal path and the second signal path receive or transmit a first signal, such as an LTE signal; the third signal path receives or transmits a second signal, such as an NR signal.

When the multi-mode radio frequency circuit is in the LTE mode, the LTE B3 signal is transmitted as shown in fig. 3, wherein

The direction indicated by the (dashed arrow) indicates the signal flow direction of the LTE B3 signal.

As shown in fig. 3, when the Transceiver sends out an LTE B3 signal, the LTE B3 signal is transmitted to the first antenna ANT1 and the second antenna ANT2 through the first signal path, and the specific signal flows are as follows: the LTE B3 signal is transmitted by the Transceiver driver, and is transmitted to the first antenna ANT1 and the second antenna ANT2 through the MHB PAMID, the SPDT (the first output terminal of the SPDT is closed), and the DP4T in sequence, and is radiated by the first antenna ANT1 and the second antenna ANT 2.

When the multi-mode RF circuit is in ENDC mode, the signal transmission modes of the LTE B3 signal and the NR N41 signal are as shown in FIG. 4, wherein

The direction indicated by (dotted arrow) indicates the signal flow direction of the LTE signal, and the direction indicated by "→" (solid arrow) indicates the signal flow direction of the NR signal.

As shown in fig. 4, when the Transceiver sends out an LTE B3 signal, the LTE B3 signal is transmitted to the first antenna ANT1 and the second antenna ANT2 through the second signal path, and the specific signal flows are as follows: the LTE B3 signal is sequentially transmitted to the first antenna ANT1 and the second antenna ANT2 through the multi-mode power amplifier module MMPA, the second Combiner2, and the double-pole four-throw switch DP4T, and radiated by the first antenna ANT1 and the second antenna ANT 2. When the Transceiver transmits an NR N41 signal, the NR N41 signal is transmitted to the third antenna ANT3 and the fourth antenna ANT4 through the endec signal path, and the specific signal flows are as follows: the NR N41 signal is transmitted to the third antenna ANT3 and the fourth antenna ANT4 through the MHB PAMID, the SPDT, and the DPDT in sequence, and radiated by the third antenna ANT3 and the fourth antenna ANT 4.

When the first antenna ANT1 and the second antenna ANT2 receive the LTE B3 signal, the main set part of the LTE B3 signal is received by the first antenna ANT1, passes through the double-pole four-throw switch DP4T, the second Combiner2 and the multi-mode power amplifier module MMPA, is transmitted to the MHB PRx LNA, is amplified by the MHB PRx LNA and is transmitted to the Transceiver. The diversity part of the LTE B3 signal is received by the second antenna ANT2, passed through the double pole four throw switch DP4T, the first Combiner1, and the MHB DRx of the MHB/hf diversity reception module, and transmitted to the MHB DRx LNA, amplified by the MHB DRx LNA, and transmitted to the Transceiver.

When the second antenna ANT2, the third antenna ANT3, the fourth antenna ANT4 and the fifth antenna ANT5 receive the NR N41 signal, the diversity part of the NR N41 signal is received by the second antenna ANT2, transmitted to the medium/high frequency diversity receiving amplifier MHB DRx LNA through the double-pole four-throw switch DP4T, the first Combiner1 and the medium/high frequency diversity receiving module MHB DRx in sequence, amplified by the medium/high frequency diversity receiving amplifier MHB DRx LNA and transmitted to the Transceiver. The main set part of the NR N41 signal is received by a third antenna ANT3, is transmitted to a medium/high frequency main set receiving amplifier MHB PRx LNA through a double-pole double-throw switch DPDT, a single-pole double-throw switch SPDT and a medium/high frequency power amplifier module MHB PAMID in turn, is amplified by the medium/high frequency main set receiving amplifier MHB PRx LNA, and is transmitted to a Transceiver Transceiver. The MIMO signal diversity part in the NR N41 signal is received by the fourth antenna ANT4, passed through the double pole double throw switch DPDT and the medium/high frequency MIMO diversity receiving module MHB DRx MIMO in sequence, transmitted to the medium/high frequency MIMO diversity receiving amplifier MHB DRx MIMO LNA, amplified by the medium/high frequency MIMO diversity receiving amplifier MHB DRx MIMO LNA, and transmitted to the Transceiver. The main set part of the MIMO signals in the NR N41 signals is received by the fifth antenna ANT5, transmitted to the medium/high frequency MIMO main set receiving amplifier MHB PRx MIMO LNA through the medium/high frequency MIMO main set receiving module MHB PRx MIMO, amplified by the medium/high frequency MIMO main set receiving amplifier MHB PRx MIMO LNA and transmitted to the Transceiver.

In another scenario, a combined signal of an LTE low band signal and an NR mid/high band signal, e.g., a B8(1TX +2RX) + N41(1TX +4RX) combined signal, may also be transmitted in the endec mode. Wherein, B8 is an LTE low band signal. The specific signal transmission flow is as follows:

when the Transceiver transmits a signal, the LTE B8 signal is transmitted to the first antenna ANT1 and the second antenna ANT2 sequentially through the low frequency power amplifier module LB PAMID, the second Combiner2, and the double pole four throw switch DP4T, and radiated by the first antenna ANT1 and the second antenna ANT 2.

When the first antenna ANT1 and the second antenna ANT2 receive the LTE B8 signal, the main-set part of the LTE B8 signal is received by the first antenna ANT1, passes through the double-pole four-throw switch DP4T, the second Combiner2, and the low-frequency power amplifier module LB PAMID in turn, is transmitted to the low-frequency main-set receiving amplifier LB PRx LNA, is amplified by the low-frequency main-set receiving amplifier LB DRx LNA, and is transmitted to the Transceiver. The diversity part of the LTE B8 signal is received by the second antenna ANT2, and is transmitted to the low frequency diversity receiving amplifier LB DRx LNA through the double pole four throw switch DP4T, the first Combiner1, and the low frequency receiving module LB DRx in sequence, and is amplified by the low frequency diversity receiving amplifier LB DRx LNA and then transmitted to the Transceiver.

Since the transmission mode of the NR N41 signal in the B8(1TX +2RX) + N41(1TX +4RX) combined signal in the endec mode is the same as the transmission mode of the NR N41 signal shown in fig. 4, it is not described here again.

The multi-mode radio frequency circuit shown in fig. 2 can also be used to implement transmission of an SA (Sounding Reference Signal) in the N41 band, where the SA SRS Signal is in a (1TX +4RX) transmission mode, and the electronic device transmits SRS signals on 4 antennas in turn. In this scenario, the ports of the double-pole four-throw switch DP4T connected to the first antenna ANT1 and the second antenna ANT2 are closed; the ports of the double pole double throw switch DPDT connected to the third antenna ANT3 and the fourth antenna ANT4 are closed.

When the Transceiver driver sends the SA SRS signal, the SA SRS signal firstly passes through the MHB PAMID and the SPDT and then selects an antenna for transmitting the signal according to the closing condition of the output port of the SPDT. When the first output terminal of the SPDT is closed, the SA SRS signal is transmitted to the double pole four throw switch DP4T connected to the first output terminal, and further transmitted to the first antenna ANT1 and the second antenna ANT2, and radiated by the first antenna ANT1 and the second antenna ANT 2; when the second output terminal of the SPDT is closed, the SA SRS signal is transmitted to the DPDT connected to the second output terminal, and further transmitted to the third antenna ANT3 and the fourth antenna ANT4, and radiated by the third antenna ANT3 and the fourth antenna ANT 4. When the first antenna ANT1 and the second antenna ANT2 receive the SA SRS signal, the main set part of the SA SRS signal is received by the first antenna ANT1, and is transmitted to the MHB PRx LNA through the double-pole four-throw switch DP4T, the single-pole double-throw switch SPDT, and the MHB PAMID module, and is amplified by the MHB PRx LNA and transmitted to the Transceiver. The diversity part of the LTE B3 signal is received by the second antenna ANT2, passed through the double pole four throw switch DP4T, the first Combiner1, the MHB DRx of the middle/high frequency diversity reception module, and transmitted to the MHB DRx LNA of the middle/high frequency diversity reception amplifier, amplified by the MHB DRx LNA of the middle/high frequency diversity reception amplifier, and transmitted to the Transceiver.

When the SA SRS signals are received by the third antenna ANT3 and the fourth antenna ANT4, the main part of the SA SRS signals is received by the third antenna ANT3, and is transmitted to the MHB PRx LNA of the medium/high frequency main receiver amplifier through the double pole double throw switch DPDT, the single pole double throw switch SPDT and the medium/high frequency power amplifier module MHB PAMID in sequence, and is amplified by the MHB PRx LNA of the medium/high frequency main receiver amplifier MHB and then transmitted to the Transceiver. The diversity part of the SA SRS signal is received by the fourth antenna ANT4, sequentially passes through the double pole double throw switch DPDT, the medium/high frequency MIMO diversity receiving module MHB DRx MIMO, is transmitted to the medium/high frequency MIMO diversity receiving amplifier MHB DRx MIMO LNA, is amplified by the medium/high frequency MIMO diversity receiving amplifier MHB DRx MIMO LNA, and is transmitted to the Transceiver.
