[0036] The RF transceiver 110 refers to the RF source of the RF system 100, which is used to realize the reception and transmission of radio signals. When the RF transceiver 110 works as a receiver, the RF transceiver 110 can detect and demodulate the radio signal received by the radiator and extract information from the radio signal.

[0042] Specifically, the second transceiver module 130 receives the radio frequency signal of the transmission frequency band of the second frequency band transmitted by the radio frequency transceiver 110, and transmits the radio frequency signal of the transmission frequency band of the second frequency band to the second radiator 300, and the second radiator 300 transmits the electromagnetic wave signal of the transmission frequency band of the second frequency band according to the radio frequency signal of the transmission frequency band of the second frequency band. In addition, the second transceiver module 130 is used to receive the signal of the diversity reception frequency band of the first frequency band through the second radiator 300, and transmit the signal of the diversity reception frequency band of the first frequency band to the radio frequency transceiver 110.

[0070] Further, in an embodiment, the second transceiver module 130 includes a first multiplexer 131, a transmitting subunit 132, and a receiving subunit 133. The first multiplexer 131 is used to be electrically connected to the second radiator 300, and is used to support the transmission frequency band of the second frequency band, the diversity reception frequency band of the second frequency band, and the CA of the diversity reception frequency band of the first frequency band.

[0071] In this embodiment, the second transceiver module 130 includes a first multiplexer 131, a transmitting subunit 132 and a receiving subunit 133. The first multiplexer 131 of the second transceiver module 130 can support the transmission frequency band of the second frequency band, the diversity reception frequency band of the second frequency band, and the CA of the diversity reception frequency band of the first frequency band.

When the radio frequency system 100 provided in the embodiment of the present application is applied to the radio frequency transceiver device 10, since the number of radiators required by the radio frequency system 100 provided in the embodiment of the present application is small, the interference between the radiators is reduced, so that the radio frequency transceiver device 10 used by the radio frequency system 100 has better communication performance in the first frequency band and the second frequency band.

[0072] See also Figure 7 , Figure 7 A circuit block diagram of a radio frequency system provided for another embodiment of the present application. In this embodiment, the first transceiver module 120 includes a transceiver module body 121 and a switch 122. The switch 122 has a first state and a second state. When the switch 122 is in the first state: the transmission frequency band of the first frequency band is used for transmission to the first radiator 200, and the transmission frequency band of the second frequency band is used for transmission to the second radiator 300. When the switch 122 is in the second state: the transmission frequency band of the first frequency band is used for transmission to the second radiator 300, and the transmission frequency band of the second frequency band is used for transmission to the first radiator 200.

[0073] In this embodiment, when the switching switch 122 is in the first state, the path between the transmission frequency band of the first frequency band and the first radiator 200 is connected, and the transmission frequency band of the first frequency band is transmitted to the first radiator 200. Correspondingly, when the switching switch 122 is in the first state, the path between the transmission frequency band of the second frequency band and the second radiator 300 is connected, and the transmission frequency band of the second frequency band is transmitted to the second radiator 300. In other words, when the switching switch 122 is in the first state: the first radiator 200 supports the transmission frequency band of the first frequency band, and the second radiator 300 supports the transmission frequency band of the second frequency band.

[0074] When the switch 122 is in the second state, the path between the transmission frequency band of the first frequency band and the second radiator 300 is connected, and the transmission frequency band of the first frequency band is transmitted to the second radiator 300. Correspondingly, when the switch 122 is in the second state, the path between the transmission frequency band of the second frequency band and the first radiator 200 is connected, and the transmission frequency band of the second frequency band is transmitted to the first radiator 200. In other words, when the switch 122 is in the second state: the second radiator 300 supports the transmission frequency band of the first frequency band, and the first radiator 200 supports the transmission frequency band of the second frequency band.

[0075] In the radio frequency system 100 provided in the embodiment of the present application, the switch 122 receives a control signal, and the control signal is used to control the state of the switch 122 .

[0076] In one embodiment, when the electronic device 1 used by the radio frequency system 100 is used, the environments of the first radiator 200 and the second radiator 300 are different. The different environments of the first radiator 200 and the second radiator 300 include different postures of the electronic device 1, which results in different shielding situations of the first radiator 200 and the second radiator 300 when held by the user, and also include different devices around the first radiator 200 and the second radiator 300 in the electronic device 1, etc., which are not limited in the embodiments of the present application. The different environments of the first radiator 200 and the second radiator 300 result in different performances of the first radiator 200 and the second radiator 300 when supporting the same frequency band.

[0077] For example, when the transmission frequency band of the first frequency band is used for communication, the antenna performance when the first radiator 200 is used to support the transmission frequency band of the first frequency band is different from the antenna performance when the second radiator 300 is used to support the transmission frequency band of the first frequency band. In the radio frequency system 100 provided in the embodiment of the present application, the first transceiver module 120 includes a switching switch 122, which can switch the transmission frequency band of the first frequency band to one of the first radiator 200 and the second radiator 300, so that the antenna performance of the one when supporting the transmission frequency band of the first frequency band is better than the antenna performance of the other of the first radiator 200 and the second radiator 300 when supporting the transmission frequency band of the first frequency band.

[0078] When the transmission frequency band of the second frequency band is used for communication, the antenna performance when the first radiator 200 is used to support the transmission frequency band of the second frequency band is different from the antenna performance when the second radiator 300 is used to support the transmission frequency band of the second frequency band. In the radio frequency system 100 provided in the embodiment of the present application, the first transceiver module 120 includes a switch 122, which can switch the transmission frequency band of the second frequency band to one of the first radiator 200 and the second radiator 300, so that the antenna performance of the one when supporting the transmission frequency band of the second frequency band is better than the antenna performance of the other of the first radiator 200 and the second radiator 300 when supporting the transmission frequency band of the second frequency band.

[0079] Specifically, when communication is performed using the transmission frequency band of the first frequency band, and when the antenna performance of the first radiator 200 when supporting the transmission frequency band of the first frequency band is better than the antenna performance of the second radiator 300 when supporting the transmission frequency band of the first frequency band, the switching switch 122 maintains the first state, or the switching switch 122 switches from the second state to the first state. Correspondingly, when communication is performed using the transmission frequency band of the first frequency band, and the antenna performance of the second radiator 300 when supporting the transmission frequency band of the first frequency band is better than the antenna performance of the first radiator 200 when supporting the transmission frequency band of the first frequency band, the switching switch 122 maintains the second state, or the switching switch 122 switches from the first state to the second state.

[0080] When communication is performed using the transmission frequency band of the second frequency band, and when the antenna performance of the first radiator 200 when supporting the transmission frequency band of the second frequency band is better than the antenna performance of the second radiator 300 when supporting the transmission frequency band of the second frequency band, the switching switch 122 maintains the second state, or the switching switch 122 switches from the first state to the second state. Correspondingly, when communication is performed using the transmission frequency band of the second frequency band, and the antenna performance of the second radiator 300 when supporting the transmission frequency band of the second frequency band is better than the antenna performance of the first radiator 200 when supporting the transmission frequency band of the second frequency band, the switching switch 122 maintains the first state, or the switching switch 122 switches from the second state to the first state.

[0081] In summary, the first transceiver module 120 provided in the embodiment of the present application includes a transceiver module body 121 and a switching switch 122, and the switching switch 122 has a first state and a second state. Therefore, when the RF system 100 provided in the embodiment of the present application is applied to the electronic device 1, the radiator used for the transmission frequency band of the first frequency band can be switched according to the environment in which the first radiator 200 and the second radiator 300 are located, and the radiator used for the transmission frequency band of the second frequency band can be switched. In this way, the antenna performance of the RF system 100 when supporting the transmission frequency band of the first frequency band or supporting the transmission frequency band of the second frequency band can be better.

[0082] For further information, please refer to Figure 7 In this embodiment, the transceiver module body 121 is used to support the transmission frequency band of the second frequency band, the diversity reception frequency band of the second frequency band, and the CA of the diversity reception frequency band of the first frequency band. The RF transceiver 110 includes a first port 111 and a first second port 112, and the first transceiver module 120 includes a first end 120a and a second end 120b, the first end 120a is electrically connected to the first port 111, and is used to transmit the transmission frequency band of the second frequency band, and the second end 120b is electrically connected to the second port 112, and is used to transmit the diversity reception frequency band of the second frequency band and the diversity reception frequency band of the first frequency band.

[0083] In this embodiment, the transceiver module body 121 is used to support the CA of the transmission band of the second frequency band, the diversity reception band of the second frequency band, and the diversity reception band of the first frequency band. The first transceiver module 120 and the RF transceiver 110 can use a second end 120b and a second port 112 to realize the transmission of signals of the diversity reception band of the second frequency band and the diversity reception band of the first frequency band.

[0084] In this embodiment, the one second end 120 b is electrically connected to the one second port 112 via one receiving signal line, so that the number of receiving signal lines required when the second end 120 b is electrically connected to the second port 112 is reduced.

[0085] See also Figure 8 , Figure 8A circuit block diagram of a radio frequency system provided in yet another embodiment of the present application. The transceiver module body 121 does not support the CA of the transmission frequency band of the second frequency band, the diversity reception frequency band of the second frequency band, and the diversity reception frequency band of the first frequency band. The radio frequency transceiver 110 includes a first port 111 and two second ports 112. The first transceiver module 120 also includes a second multiplexer 123. The second multiplexer 123 is electrically connected to the transceiver module body 121, and the second multiplexer 123 is used to support the CA of the transmission frequency band of the second frequency band, the diversity reception frequency band of the second frequency band, and the diversity reception frequency band of the first frequency band. The second multiplexer 123 includes a transmitting end 123a, a first receiving end 123b and a second receiving end 123c. The transmitting end 123a is electrically connected to the first port 111 for transmitting a transmitting frequency band of a second frequency band. The first receiving end 123b is electrically connected to one of the two second ports 112 for transmitting a diversity receiving frequency band of the first frequency band. The second receiving end 123c is electrically connected to the other of the two second ports 112 for transmitting a diversity receiving frequency band of the second frequency band.

[0086] When the transceiver module body 121 does not support the transmission frequency band of the second frequency band, the diversity reception frequency band of the second frequency band, and the CA of the diversity reception frequency band of the first frequency band, the first transceiver module 120 includes a second duplexer, and the second duplexer supports the transmission frequency band of the second frequency band, the diversity reception frequency band of the second frequency band, and the CA of the diversity reception frequency band of the first frequency band, so that the RF system 100 can use the first radiator 200 to support the transmission frequency band of the second frequency band, the diversity reception frequency band of the second frequency band, and the diversity reception frequency band of the first frequency band.

[0087] In this embodiment, the transmitting end 123a is electrically connected to the first port 111 via a transmitting signal line, the first receiving end 123b is electrically connected to one of the two second ports 112 via a receiving signal line, and the second receiving end 123c is electrically connected to the other of the two second ports 112 via another receiving signal line.

[0088] The RF system 100 provided in the embodiment of the present application uses a second duplexer to support the CA of the transmission frequency band of the second frequency band, the diversity reception frequency band of the second frequency band, and the diversity reception frequency band of the first frequency band when the transmission module body does not support the CA of the transmission frequency band of the second frequency band, the diversity reception frequency band of the second frequency band, and the diversity reception frequency band of the first frequency band, and also enables the RF system 100 to use the first radiator 200 to support the transmission frequency band of the second frequency band, the diversity reception frequency band of the second frequency band, and the diversity reception frequency band of the first frequency band.

[0089] In combination with the RF system 100 described in any of the foregoing items, in one embodiment, the RF system 100 is used to implement 4G and 5G dual connectivity (E-UTRAN New Radio Dual Connectivity, ENDC) of the first frequency band and the second frequency band; or, the RF system 100 is used to implement CA of the first frequency band and the second frequency band of the LTE frequency band; or, the RF system 100 is used to implement CA of the first frequency band and the second frequency band of the NR frequency band.

[0090] For example, in one embodiment, the radio frequency system 100 is used to implement ENDC of the first frequency band and the second frequency band. ENDC is a non-standalone (NSA) function that can simultaneously connect to a 4G Long Term Evolution (LTE) network and a 5G New Radio (NR) network.

[0091] ENDC allows the electronic device 1 used by the radio frequency system 100 to be connected to the 5G base station and the 4G base station at the same time to achieve higher data transmission speed and better coverage. Through ENDC, the electronic device 1 used by the radio frequency system 100 can obtain faster speeds on the 5G network provided by the 5G base station, while maintaining connection stability on the 4G network provided by the 4G base station, thereby improving the overall network experience.

[0092] For example, in one embodiment, the RF system 100 can implement ENDC of LB band + LB band, or the RF system 100 can implement ENDC of MB band + MB band. For example, the RF system 100 can implement ENDC of B20 band and N28 band.

[0093] In another embodiment, the radio frequency system 100 is used to implement uplink carrier aggregation (UL CA) of the first frequency band and the second frequency band of the LTE frequency band.

[0094] In yet another embodiment, the radio frequency system 100 is used to implement uplink carrier aggregation (UL CA) of the first frequency band and the second frequency band of the NR frequency band.

[0095] The radio frequency system 100 provided in the embodiment of the present application can reduce the number of radiators, and can realize a non-independent networking connection of a LB band + LB band (also referred to as L+L) combination by using a first radiator 200 and a second radiator 300 to meet the communication needs of some countries and regions (such as America).

[0096] The radio frequency system 100 provided in the embodiment of the present application can reduce the number of radiators required for the radio frequency system 100 to support the first frequency band and the second frequency band, reduce the cost of the radio frequency transceiver 10 and the electronic device 1 used by the radio frequency system 100, and also reduce interference between radiators.

[0097] The above is part of the implementation methods of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present application. These improvements and modifications are also considered to be within the scope of protection of the present application.
