and the controller is connected with the radio frequency signal receiving and transmitting assembly and the access switcher and is used for acquiring the working states of the NR radio frequency assembly and the Wi-Fi radio frequency assembly and controlling the access switcher to work according to the working states.

and the control module is used for controlling the first end of the access switcher to be communicated with the second end of the access switcher under the condition that the Wi-Fi radio frequency assembly and the NR radio frequency assembly work simultaneously so as to enable the first radio frequency antenna to work in a Wi-Fi-2.4GHz frequency band.

In a fourth aspect, an embodiment of the present application provides an electronic device, including a processor, a memory, and a program or instructions stored on the memory and executable on the processor, where the program or instructions, when executed by the processor, implement the control method of the radio frequency circuit according to the second aspect; and a radio frequency circuit as in any one of the first aspect.

In the embodiment of the application, the radio frequency circuit comprises a radio frequency antenna component, wherein the second radio frequency antenna is a general Wi-Fi-2.4GHz frequency band antenna and is connected with the Wi-Fi radio frequency component. The first radio frequency antenna is generally an LTE antenna and is connected to an LTE radio frequency component. A signal extractor corresponding to a Wi-Fi-2.4GHz frequency band is arranged between the first radio frequency antenna and the LTE radio frequency component, a first end of the signal extractor is connected with the LTE radio frequency component, a second end of the signal extractor is connected with the first radio frequency antenna, and a third end of the signal extractor is connected with the Wi-Fi radio frequency component. The signal extractor can extract signals of a Wi-Fi-2.4GHz frequency band, so that the first radio frequency antenna can simultaneously deal with signals of an LTE frequency band and signals of a Wi-Fi-2.4GHz frequency band. That is to say, by arranging the signal extractor, the first radio frequency antenna originally applied to the LTE frequency band is developed to be applicable to the Wi-Fi-2.4GHz frequency band.

Meanwhile, a path switcher is arranged, a first end of the path switcher is connected with the Wi-Fi radio frequency assembly, a second end of the path switcher is connected with a third end of the signal extractor, and the third end of the path switcher is connected with the second radio frequency antenna.

Specifically, the work states of the NR radio frequency component and the Wi-Fi radio frequency component are obtained through the controller. If the Wi-Fi radio frequency component and the NR radio frequency component do not work simultaneously, namely when the radio frequency circuit does not enable the 2.4GHz frequency band of Wi-Fi and the N41 frequency band of NR simultaneously, the access switcher connects the first end of the access switcher with the third end of the access switcher, and the Wi-Fi-2.4G signals are transmitted and received through the second radio frequency antenna.

If the Wi-Fi radio frequency component and the NR radio frequency component work simultaneously, namely the radio frequency circuit enables the 2.4GHz frequency band of Wi-Fi and the N41 frequency band of NR simultaneously, the control access switcher connects the first end with the second end, and at the moment, the first radio frequency antenna receives and transmits Wi-Fi-2.4G signals. Because the first radio frequency antenna is the antenna corresponding to the LTE frequency band, the isolation between the first radio frequency antenna and the NR antenna is relatively better, the working antenna of the Wi-Fi radio frequency component is switched to the first radio frequency antenna, the Wi-Fi antenna can obtain better isolation between the Wi-Fi antenna and the NR antenna, the signal interference between the 2.4GHz frequency band of Wi-Fi and the N41 frequency band of NR can be effectively reduced, the Wi-Fi and the NR can work simultaneously, and the throughput of the Wi-Fi and the NR is not influenced.

The following describes a radio frequency circuit, a control method and device of the radio frequency circuit, and an electronic device according to an embodiment of the present application with reference to fig. 1 to 6.

In some embodiments of the present application, fig. 1 illustrates one of the block diagrams of a radio frequency circuit 100 according to an embodiment of the present application, and specifically, as illustrated in fig. 1, the radio frequency circuit 100 includes:

a radio frequency antenna assembly comprising a first radio frequency antenna 102 and a second radio frequency antenna 104;

radio frequency signal transceiving components including an LTE radio frequency component 106 and a Wi-Fi radio frequency component 108;

a signal extractor 110, a first end of the signal extractor 110 is connected to the LTE rf component 106, and a second end of the signal extractor 110 is connected to the first rf antenna 102;

a path switch 112, a first terminal of the path switch 112 is connected to the Wi-Fi rf component 108, a second terminal of the path switch 112 is connected to a third terminal of the signal extractor 110, and the third terminal of the path switch 112 is connected to the second rf antenna 104;

In the embodiment of the present application, the rf circuit 100 includes an rf antenna assembly, wherein the second rf antenna 104 is a general Wi-Fi-2.4GHz band antenna, and is connected to the Wi-Fi rf assembly 108. The first rf antenna 102, which is typically an LTE antenna, is connected to an LTE rf component 106. A signal extractor 110 corresponding to a Wi-Fi-2.4GHz band is disposed between the first rf antenna 102 and the LTE rf component 106, a first end of the signal extractor 110 is connected to the LTE rf component 106, a second end is connected to the first rf antenna 102, and a third end is connected to the Wi-Fi rf component 108. The signal extractor 110 can extract signals in the Wi-Fi-2.4GHz band, so that the first RF antenna 102 can simultaneously cope with signals in the LTE band and signals in the Wi-Fi-2.4GHz band. That is, by providing the signal extractor 110, the first rf antenna 102 originally applied to the LTE frequency band is extended to be applicable to the Wi-Fi-2.4GHz frequency band.

Meanwhile, a path switch 112 is provided, a first terminal of the path switch 112 is connected to the Wi-Fi rf component 108, a second terminal of the path switch 112 is connected to a third terminal of the signal extractor 110, and the third terminal of the path switch 112 is connected to the second rf antenna 104. The path switch 112 can switch the first end to communicate with the second end, or switch the first end to communicate with the third end.

Specifically, the operating states of the NR radio frequency components and the Wi-Fi radio frequency components 108 are obtained by the controller. If the Wi-Fi rf components 108 and the NR rf components are not operating simultaneously, i.e., when the rf circuit 100 is not simultaneously enabled with the Wi-Fi 2.4GHz band and the NR N41 band, the access switch 112 connects the first end thereof to the third end thereof, and transmits and receives Wi-Fi-2.4G signals through the second rf antenna 104.

If the Wi-Fi rf component 108 and the NR rf component operate simultaneously, that is, the rf circuit 100 enables the 2.4GHz band of Wi-Fi and the N41 band of NR simultaneously, the control path switch 112 connects the first end thereof to the second end thereof, and at this time, the first rf antenna 102 transmits and receives Wi-Fi-2.4G signals. Because the first radio frequency antenna 102 is an antenna corresponding to an LTE frequency band, the isolation between the first radio frequency antenna 102 and an NR antenna is relatively better, and the working antenna of the Wi-Fi radio frequency component 108 is switched to the first radio frequency antenna 102, so that the Wi-Fi antenna can obtain better isolation from the NR antenna, the signal interference between a 2.4GHz frequency band of Wi-Fi and an N41 frequency band of NR is effectively reduced, and meanwhile, Wi-Fi and NR can work simultaneously, and it is ensured that the throughput of Wi-Fi and NR is not affected.

In some embodiments of the present application, as shown in fig. 1, the radio frequency antenna assembly further comprises:

a third rf antenna 114 connected to the LTE rf component 106; the third rf antenna 114 is an LTE primary set receiving-transmitting antenna, and the first rf antenna 102 is an LTE diversity receiving antenna.

In this embodiment, the rf antenna assembly includes a third rf antenna 114, the third rf antenna 114 is specifically an LTE master set receiving-transmitting antenna, the first rf antenna 102 is an LTE diversity receiving antenna, that is, the signal extractor 110 is provided, so that the LTE diversity receiving antenna can receive or transmit signals in a Wi-Fi 2.4GHz band, when the rf circuit 100 simultaneously enables the Wi-Fi 2.4GHz band and the NR N41 band, the control path switch 112 connects the first end to the second end, and at this time, the first rf antenna 102 receives and transmits Wi-Fi-2.4G signals, so as to reduce interference between the Wi-Fi 2.4GHz band and the NR N41 band.

In some embodiments of the present application, as shown in fig. 1, the radio frequency antenna assembly further comprises a plurality of fourth radio frequency antennas 116;

In the embodiment, as shown in fig. 1, the first rf antenna 102 is farther away from the fourth rf antennas 116, and the second rf antenna 104 is closer to the fourth rf antennas 116, so that a first isolation between the first rf antenna 102 and the fourth rf antennas 116 is greater than a second isolation between the second rf antenna 104 and the fourth rf antennas 116. Therefore, when the radio frequency circuit 100 enables the 2.4GHz band of Wi-Fi and the N41 band of NR simultaneously, the control path switch 112 connects the first end thereof to the second end thereof, and at this time, the first radio frequency antenna 102 receives and transmits Wi-Fi-2.4G signals, so that the isolation between the Wi-Fi-2.4GHz band and the N41 can be improved, and the interference between the 2.4GHz band of Wi-Fi and the N41 band of NR can be effectively reduced.

Specifically, fig. 2 shows a second structure diagram of the rf circuit 100 according to the embodiment of the present application, and fig. 3 shows an antenna layout diagram of an electronic device.

When Wi-Fi 2.4G and N41 do not work simultaneously, the antenna can be started, and a better signal effect is obtained.

Therefore, when the Wi-Fi 2.4G and the N41 work simultaneously, the Wi-Fi 2.4G antenna 2 (the first radio frequency antenna 102) is switched to, so that the isolation between the Wi-Fi 2.4GHz band and the N41 band is higher.

The second rf antenna 104 is an LTE 4G diversity receiving antenna, and its working frequency band can be switched between an LTE 4G frequency band and a WiFi-2.4GHz frequency band. The third rf antenna 114 is a Wi-Fi antenna, and the working frequency band of the antenna is Wi-Fi-2.4GHz frequency band.

Specifically, the single-pole double-throw switch can switch the movable end to be connected with the first stationary end or the second stationary end under the control of a control signal of the controller, so as to switch the antenna of the Wi-Fi-2.4GHz frequency band, when the radio frequency circuit 100 enables the 2.4GHz frequency band of Wi-Fi and the N41 frequency band of NR at the same time, the control path switcher 112 connects the first end with the second end, and at this time, the first radio frequency antenna 102 receives and transmits Wi-Fi-2.4G signals, so as to reduce interference between the 2.4GHz frequency band of Wi-Fi and the N41 frequency band of NR.
