It is to be understood that the data so used may be interchanged, as appropriate, such that embodiments of the present application may be implemented in sequences other than those illustrated or described herein, and that the objects identified by "first," "second," etc. are generally of a type, and are not limited to the number of objects, such as the first object may be one or more. Furthermore, in the description and claims, "and/or" means at least one of the connected objects, and the character "/", generally means that the associated object is an "or" relationship.
The radio frequency circuit provided by the embodiment of the application is described in detail below through specific embodiments and application scenes thereof with reference to the accompanying drawings.
As shown in fig. 1, an embodiment of the present application provides a radio frequency circuit 100, which is applied to an electronic device, wherein the radio frequency circuit 100 includes a radio frequency transceiver 110, a first radio frequency module 120, a second radio frequency module 130, a third radio frequency module 140, a first antenna 150, a second antenna 160, and a third antenna 170.
The rf transceiver 110 is connected to the first input terminal of the first rf module 120, the first input terminal of the second rf module 130, and the first input terminal of the third rf module 140, respectively; a first output end of the first rf module 120 is connected to the first antenna 150, and a second output end of the first rf module 120 is connected to a second input end of the second rf module 130; the first output end of the second rf module 130 is connected to the second antenna 160, and the second output end of the second rf module 130 is connected to the second input end of the third rf module 140; the first output end of the third rf module 140 is connected to the third antenna 170.
The first rf module 120 may be configured to amplify the low frequency signal of the first network mode. The second rf module 130 may be configured to amplify the intermediate frequency signal of the first network mode or the low frequency signal of the first network mode processed by the first rf module 120. The third rf module 140 may be configured to amplify the intermediate frequency signal of the first network mode after being processed by the second rf module 130.
That is, the low frequency signal in the first network mode may be directly radiated through the first antenna 150 after the amplification processing of the first rf module 120, or may be radiated through the second antenna 160 after the amplification processing of the first rf module 120 and the amplification processing of the second rf module 130. Similarly, the intermediate frequency signal in the first network mode may be directly radiated through the second antenna 160 after the amplification processing of the second rf module 130, or may be radiated through the third antenna 170 after the amplification processing of the third rf module 140 after the amplification processing of the second rf module 130.
Based on the scheme, because the signals of the same frequency band can be switched and connected with the antennas of different radio frequency modules to radiate, the installation positions of the antennas of the different radio frequency modules are necessarily different, namely, the signals of the same frequency band can radiate through the antennas positioned at different positions, the risk that the performance of the antennas can be influenced when a user holds the electronic equipment because the holding area is just positioned above the antennas can be reduced, and therefore the communication experience of the user can be improved.
Optionally, the first rf module 120 may be further configured to amplify the low frequency signal of the second network mode; the second rf module 130 may be further configured to amplify a low-frequency signal of a third network mode or an intermediate-frequency signal of the third network mode; the third rf module 140 may be further configured to amplify the intermediate frequency signal of the second network mode or the high frequency signal of the second network mode; the signal transmission rate of the first network mode is smaller than the signal transmission rate of the second network mode, and the signal transmission rate of the second network mode is smaller than the signal transmission rate of the third network mode.
Optionally, the first network mode may be a second generation mobile communication technology (Global System for Mobile Communications, GSM), the second network mode may be a third generation mobile communication technology 3G or a fourth generation mobile communication technology 4G, and the third network mode may be a fifth generation mobile communication technology 5G.
Based on the above scheme, the first radio frequency module can also be used for amplifying the low-frequency signal of the second network mode; the second radio frequency module can also be used for amplifying a low-frequency signal of a third network mode or an intermediate-frequency signal of the third network mode; the third radio frequency module can also be used for amplifying the intermediate frequency signal of the second network mode or the high frequency signal of the second network mode, so that the radio frequency circuit provided by the embodiment of the application can realize two amplifying paths of the first network mode by multiplexing the radio frequency modules of other network modes under the condition of meeting the communication requirements of multiple network modes. Therefore, the radio frequency power consumption of the electronic equipment is reduced to the greatest extent, and the cruising ability of the electronic equipment is improved.

The second output switch 135 may be configured to open a path between the third signal amplifier 132 and the second antenna 160 when the signal strength of the intermediate frequency signal in the first network mode is greater than a first threshold; and when the signal strength of the intermediate frequency signal in the first network mode is less than or equal to the first threshold value, a path between the third signal amplifier 132 and the third rf module 140 is opened.

In addition, the 5G low frequency (5 g_lb) signal can be input to the second rf module 130 from the rf transceiver 110, amplified by the second input switch 133 and then directly radiated through the second antenna 160 via the second output switch 135. The GSM intermediate frequency signal (gsm_mb) and the 5G intermediate frequency (5g_mb) signal may be input to the second rf module 130 by the rf transceiver 110, and then enter the third signal amplifier 132 to be amplified after passing through the third input switch 134, and then be directly radiated out through the second antenna 160 by passing through the second output switch 135; or the gsm_mb signal may be input to the third rf module 140 through the second output switch 135 into the fourth input switch 142.
With continued reference to fig. 2, the third rf module 140 may include a fourth signal amplifier 141, a fourth input switch 142, and a third output switch 143.

An input terminal of the fifth signal amplifier 144 is connected to the rf transceiver 110, and an output terminal of the fifth signal amplifier 144 is connected to a second input terminal of the third output switch 143.
For example, referring to fig. 2, after the gsm_mb signal is input into the third rf module 140, the gsm_mb signal may be amplified again by the fourth signal amplifier 141 in the third rf module 140, and then radiated through the third antenna 170 by the third output switch 140.
