All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

It will be appreciated that the data so used may be interchanged under appropriate circumstances such that embodiments of the application may be practiced in sequences other than those illustrated or described herein, and that the terms "first," "second," and the like are generally used herein in a generic sense and do not limit the number of terms, e.g., the first term can be one or more than one. In addition, "and/or" in the specification and claims means at least one of connected objects, a character "/" generally means that a preceding and succeeding related objects are in an "or" relationship.
The radio frequency receiving circuit provided by the embodiment of the present application is described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios thereof.
The method of the embodiments of the present application is applied to an electronic device, such as a User Equipment (UE), which may refer to an access terminal, a subscriber unit, a subscriber station, a mobile station, a remote terminal, a mobile device, a user terminal, a wireless communication device, a user agent, or a user equipment. The terminal device may also be a cellular phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA), a handheld device with wireless communication capability, a computing device or other processing device connected to a wireless modem, a vehicle mounted device, a wearable device.
It should be noted that, in the prior art, taking a 6-antenna architecture as an example, a basic block diagram of 4G and 5G radio frequency communication is shown in fig. 1, where a first radio frequency antenna 01 and a second radio frequency antenna 02 are a 4G primary set receiving (PRx) antenna and a diversity receiving (DRx) antenna, respectively, a third radio frequency antenna 03 and a fourth radio frequency antenna 04 are a 5G PRx antenna and a DRx antenna, respectively, a fifth radio frequency antenna 05 and a sixth radio frequency antenna 06 are a PRx MIMO antenna and a DRx MIMO antenna, respectively, and for 4G and 5G frequency bands, corresponding MIMO antennas may be shared. The radio frequency front end architecture 1 is respectively connected with 6 antennas and a modem (modem)2, and the modem 2 is further connected with a Central Processing Unit (CPU) 3. Radio frequency signals received by the 6 antennas are transmitted to the modem 2 through the radio frequency front end architecture 1, and the modem 2 processes signal data.
Since the MIMO antenna is mainly used for auxiliary transceiving to improve the performance of the terminal, the efficiency of the PRx antenna and the DRx antenna of the terminal may be higher than that of the MIMO antenna.
The current rf front end architecture 1 includes a plurality of rf receiving modules, including a main set receiving module and a diversity receiving module, and the circuit architectures of the main set receiving module and the diversity receiving module are substantially the same, so only the main set receiving module is used for the description in this embodiment.
As shown in fig. 2, the main set receiving module of the existing rf front-end architecture mainly includes 2 low noise amplifiers (LNA1, LNA3) for amplifying high frequency signals, 2 low noise amplifiers (LNA2, LNA4) for amplifying medium and high frequency signals, and 1 low noise amplifier (LNA5) for amplifying low frequency signals. And the input end of each low noise amplifier is connected with the movable end of a single-pole multi-throw switch, and a plurality of immovable ends of the single-pole multi-throw switch are connected with a plurality of signal receiving ports of the main set receiving module. Each signal receiving port is connected with an antenna to receive radio frequency signals of the antenna, the controller 4 controls the movable end of the single-pole multi-throw switch to be connected with the corresponding immovable end, the signals are amplified by the corresponding low noise amplifier through the corresponding single-pole multi-throw switch and then transmitted to the modem 2 through the output interface 5, and the modem 2 processes signal data.
When the electronic device is in the dual-card connection state, the principle of 5G priority is followed, for example, when a dual-card user is connected to two radio frequency signals with close frequency bands (such as 4G B41 frequency band and 5G n41 frequency band), the signal in the 5G n41 frequency band is preferentially on the network. Since the radio frequency signals of the 4G B41 band and the 5G n41 band share one medium-high frequency signal low noise amplifier (LNA4), and different signal receiving ports are connected for receiving only by switching between the movable end and the stationary end of the single-pole multi-throw switch connected with the LNA4, the radio frequency signals of the 5G n41 band preempt the low noise amplifier LNA4 through the signal receiving ports, and the radio frequency signals of the 4G B41 band can only be amplified by using the other medium-high frequency signal low noise amplifier LNA2, but since the low noise amplifier LNA2 is connected with the MIMO antenna, the efficiency is low, and when the MIMO antenna is held by a hand, the efficiency of the MIMO antenna is still lower, so that the MIMO antenna is difficult to stay in a network, even the situation of wire drop occurs, and the user experience is greatly influenced.
As shown in fig. 3, an embodiment of the present application provides a radio frequency receiving circuit, including:
the device comprises a first low noise amplifier 6, a second low noise amplifier 7, a switch module, a first antenna 8, a second antenna 9 and a controller 4;

the switch module has a first state and a second state, and when the switch module is in the first state, the first low noise amplifier 6 is communicated with the first antenna 8 through the switch module, and the second low noise amplifier 7 is communicated with the second antenna 9 through the switch module;
under the condition that the switch module is in the second state, the second low noise amplifier 7 is communicated with the first antenna 8 through the switch module, or the second low noise amplifier 7 is communicated with the second antenna 9 through the switch module. In the embodiment of the application, the controller 4 is connected with the switch module, when the electronic device is in a state of dual card connection, the controller 4 controls the switch module to be in a first state, otherwise, the switch module is in a second state; the dual card state refers to a state in which the electronic device can receive a first network system radio frequency signal and a second network system radio frequency signal at the same time, for example, the first network system radio frequency signal is a 4G signal, and the second network system radio frequency signal is a 5G signal.
In the embodiment of the application, when the first antenna 8 and the second antenna 9 of the radio frequency receiving circuit receive antenna signals of the same frequency or similar frequency bands, the switch module is switched to the first state, so that the first antenna 8 is communicated with the first low noise amplifier 6, and the second antenna 9 is communicated with the second low noise amplifier 7, so that two antennas on the electronic device for receiving antenna signals of the same frequency or similar frequency bands can respectively correspond to different low noise amplifiers to receive signals, and the same low noise amplifier does not need to be contended, thereby solving the problem that one of the two antennas for receiving antenna signals of the same frequency or similar frequency bands is idle due to the contention of the low noise amplifier connected with the shared single-pole multi-throw switch, and improving the receiving efficiency of the same frequency signals. It should be noted that the number of the low noise amplifiers may be not only two, but also three or more, and correspondingly, the number of the antennas may also be three or more, and the manner of controlling the low noise amplifiers to communicate with the corresponding antennas through the switch module is also within the protection scope of the present embodiment.
In the embodiment of the present application, the controller 4 controls the stationary end of the switch in the switch module to be switched to the corresponding movable end, and controls the radio frequency signal received by the antenna to be amplified by the corresponding Low Noise Amplifier (LNA) through the corresponding switch.
