In this embodiment, when other transceiver modules (such as the second rf transceiver module 6) in the rf circuit except for the first rf transceiver module 1 transmit rf signals, the first movable arm of the first switch module 3 in each first rf receiving path may be connected to the second contact. Then, the first rf receiving path is grounded and will not be affected by the rf signals transmitted by other transceiver modules, so that the possibility of interference between antennas connected to different rf transceivers can be reduced.

When the first rf receiving path needs to receive the rf signal, the first movable arm of the first switch module 3 may be connected to the first contact, and at this time, the first rf receiving path may normally receive the rf signal.
Optionally, as shown in fig. 4, the fourth contact of the second switch module 8 is grounded through a second resistor R2.
In this embodiment, the fourth contact of the second switch module 8 is grounded through the second resistor R2, so that the rf circuit can perform impedance matching conveniently, thereby improving the performance of the rf circuit. The second resistor R2 may be 50 Ω.
Optionally, the first radio frequency transceiver module 1 is a 4G radio frequency transceiver module, and the second radio frequency transceiver module 6 is a 5G radio frequency transceiver module.
In this embodiment, the first rf transceiver module 1 is a 4G rf transceiver module, and the second rf transceiver module 6 is a 5G rf transceiver module, so that the possibility of interference between the antenna for transmitting in 4G and the antenna for receiving in 5G can be reduced, and the possibility of interference between the antenna for transmitting in 5G and the antenna for receiving in 4G can also be reduced. It should be noted that the first rf transceiver module 1 may also be a 5G rf transceiver module, and the second rf transceiver module 6 may be a 6G rf transceiver module.
For example, the first switch module 3 may be controlled by the second rf transceiver module 6, and the second switch module 8 may be controlled by the first rf transceiver module 1. When the dual-card dual-standby or dual-card dual-pass operation is performed, as shown in fig. 4, the second rf transmitting path of the second rf transceiver module 6 switches the first switch module 3 of the 4G B41 receiving path (i.e., the first rf receiving path of the first rf transceiver module 1) to the ground at the transmitting power transmitting gap of N41, so as to isolate the N41 power from entering the first amplifier 5 (e.g., a low noise amplifier) in hardware, thereby protecting the first amplifier 5 of the 4G receiving path from the influence of the NR (New Radio, New air interface) transmitting power. Similarly, when LTE (Long Term Evolution) B41 transmission power is working (transmitting through the first rf transmission path of the first rf transceiver module 1), the second switch module 8 of the NR N41 reception path (i.e. the second rf reception path of the second rf transceiver module 6) is switched to ground, so as to protect the low noise of the NR reception path (i.e. the second rf reception path of the second rf transceiver module 6) from being affected by the B41 transmission power.
In a first scenario, when a Dual-card mobile phone enters an EN-DC (eNB NR Dual Connection, Dual Connection between a 5G radio access network and a 4G radio access network) Dual-Connection mode, a mobile phone background detects that a first communication card is in an endec B xx + N41 registration Connection state, a second communication card system enters an LTE B41 registration Connection state, a preset algorithm logic is started to control single-pole double-throw switches of different receiving paths, and the specific flow is as follows:
the dual-card mobile phone enters an EN-DC working scene, a mobile phone background detects that a first communication card is in an ENDC B xx + N41 registration connection state, a second communication card system enters an LTE B41 registration connection state, and the background starts to control a 4G and NR radio frequency receiving channel switch. Under the condition that an EN-DC connection base station searches for a network by using an LTE B41 service, a switch in an LTE 4G radio frequency receiving path is arranged on the ground in an NR N41 transmitting time slot; under the condition that an LTE B41 connection base station is used for carrying out EN-DC network searching, the switch of the NR N41 radio frequency receiving path is set to be at the ground in a B41 transmission time slot.
In a second scenario, in addition to the dual card interference situation, in a specific EN-DC connection mode, for example, LTE B41+ NR N41, may also perform risk control through the above scheme, avoiding the problem of receiving co-channel interference caused by transmission between B41 and N41, and the specific procedure is as follows:
the single-card mobile phone enters an EN-DC working scene, the mobile phone background detects that the mobile phone enters a specific EN-DC connection, such as B41+ N41 enters a registration connection state, and the background starts logic control on 4G and NR radio frequency receiving channel switches. In the case of N41 transmission, the switch of the LTE 4G radio frequency receive path is set to ground within the NR N41 transmission slot; in the case of B41 transmission, the switch of the NR N41 radio frequency receive path is set to ground during the B41 transmit time slot.
Therefore, the EN-DC co-frequency coexistence scene of the terminal equipment is optimized through the optimization of the radio frequency front end architecture. Specifically, the device performance and the application reliability are ensured in the same-frequency work under the EN-DC B41+ N41 and double-card double-standby single-pass or double-card double-pass scenes.
Optionally, the radio frequency circuit is applied to a terminal device, the terminal device includes a first communication card and a second communication card, and the first communication card and the second communication card respectively transmit or receive a radio frequency signal through different radio frequency transceiver modules of the first radio frequency transceiver module and the second radio frequency transceiver module.
In this embodiment, the first communication card may transmit or receive a radio frequency signal through a first radio frequency transceiver module, and the second communication card may transmit or receive a radio frequency signal through a second radio frequency transceiver module; or, the second communication card may transmit or receive a radio frequency signal through the first radio frequency transceiver module, and the first communication card may transmit or receive a radio frequency signal through the second radio frequency transceiver module. Therefore, the possibility of interference between the antennas connected with different radio frequency transceivers can be reduced on the dual-card terminal.
Optionally, the first amplifier and the second amplifier are both low noise amplifiers.
In this embodiment, the first amplifier and the second amplifier are both low noise amplifiers, and the interference of the noise of the amplifiers to the signal can be reduced to improve the signal-to-noise ratio of the output.
