As shown in fig. 1 and fig. 2, an embodiment of the present application provides a radio frequency circuit, including: the radio frequency transceiver module comprises a first radio frequency transceiver module 10, a second radio frequency transceiver module 20, a first radio frequency receiving module 30, a second radio frequency receiving module 40, a switch module and a plurality of antennas;
the switch module comprises a first switch 51, a second switch 52 and a third switch 53;

It can be understood that, in a case that the at least two antennas include a third antenna 63 and a fourth antenna 64, the first rf transceiver module 10 may be electrically connected to the first antenna 61 through the first switch 51, may also be electrically connected to the second antenna 62 through the first switch 51 and the second switch 52, and may be electrically connected to the third antenna 63 or the fourth antenna 64 through the first switch 51, the second switch 52 and the third switch 53, so that the rf signal output by the first rf transceiver module 10 may be transmitted through any one of the first antenna 61, the second antenna 62, the third antenna 63 and the fourth antenna 64, thereby implementing the function of 1T4R of the rf circuit; accordingly, the second rf transceiver module 20 can be electrically connected to the third antenna 63 or the fourth antenna 64 through the third switch 53, so as to implement the function of 1T2R of the rf circuit.
In addition, compared with the radio frequency circuit which needs to be provided with other radio frequency devices such as a combiner, the radio frequency circuit can realize the function of 1T4R and the function of 1T2R of the radio frequency circuit by only arranging three switches, thereby simplifying the circuit structure of the radio frequency circuit.
Moreover, because only one first switch 51 is arranged between the first rf transceiver module 10 and the first antenna 61, the first rf transceiver module 10 can be arranged close to the first antenna 61, which can shorten the routing distance from the first rf transceiver module 10 to the first antenna 61, thereby reducing the transmission insertion loss of the path and improving the transmission efficiency of the rf circuit in the path; furthermore, because the transmission insertion loss of the path is smaller, the output power of the power amplifier of the path can be reduced, and the power consumption performance of the radio frequency circuit is further improved.
Correspondingly, only one third switch 53 is arranged between the second rf transceiver module 20 and the third antenna 63 or the fourth antenna 64, so that the second rf transceiver module 20 can be arranged close to the third antenna 63 or the fourth antenna 64, and the routing distance between the second rf transceiver module 20 and the third antenna 63 or the fourth antenna 64 can be shortened, thereby reducing the transmission insertion loss of the path and improving the transmission efficiency of the rf circuit in the path; furthermore, because the transmission insertion loss of the path is smaller, the output power of the power amplifier of the path can be reduced, and the power consumption performance of the radio frequency circuit is further improved.
Optionally, the first end of the first switch 51 includes four first ports, one of the four first ports is electrically connected to a first target rf receiving module (not shown) in the first rf receiving module 30, and the other three ports of the four first ports are electrically connected to the first rf transceiving module 10;

In an example, in a case that the first rf transceiver module 10 includes three first rf transceiver modules, the first switch 51 may be a double-pole four-throw switch; wherein, because the double-pole four-throw switch has better isolation and spurious suppression function, through choosing double-pole four-throw switch for use as first switch 51, can not only reduce mutual interference and outband spurious between the radio frequency module, can also improve radio frequency circuit's sensitivity, emission index and radio frequency function, and then improve radio frequency circuit's receiving and dispatching performance.
Optionally, the first end of the second switch 52 includes four third ports, one of the four third ports is electrically connected to the second end of the first switch 51, two of the three ports are electrically connected to other rf receiving modules in the first rf receiving module 30 except the first target rf receiving module, another one of the three third ports is electrically connected to the second rf receiving module 40, and the three third ports are ports of the four third ports except the port electrically connected to the second end of the first switch 51;

In an example, in the case that the first rf receiving module 30 includes three first rf receiving modules, the second switch 52 may be a double-pole four-throw switch; because the double-pole four-throw switch has better isolation and stray suppression functions, the double-pole four-throw switch is selected as the second switch 52, so that the mutual interference and out-of-band stray among radio frequency modules can be reduced, the sensitivity, emission indexes and radio frequency functions of the radio frequency circuit can be improved, and the receiving and transmitting performance of the radio frequency circuit is improved.
Optionally, the first end of the third switch 53 includes four fifth ports, one of the four fifth ports is electrically connected to the second switch 52, and the other three of the four fifth ports are electrically connected to the second rf transceiver module 20;
the second terminal of the third switch 53 includes two sixth ports, and the at least two antennas include a third antenna 63 and a fourth antenna 64, and the two sixth ports are electrically connected to the third antenna 63 and the fourth antenna 64, respectively.

In an example, in the case that the second rf transceiving module 20 includes three first rf transceiving modules, the third switch 53 may be a double-pole four-throw switch; because the double-pole four-throw switch has better isolation and stray suppression functions, the double-pole four-throw switch is selected as the third switch 53, so that the mutual interference and out-of-band stray among the radio frequency modules can be reduced, the sensitivity, the emission index and the radio frequency function of the radio frequency circuit can be improved, and the receiving and transmitting performance of the radio frequency circuit is improved.
