Abstract

The invention discloses a radio frequency receiving circuit, a radio frequency signal receiving method and device and electronic equipment, and relates to the technical field of communication. The radio frequency receiving circuit comprises a first low-noise amplifier, a second low-noise amplifier, a switch module, a first antenna, a second antenna and a controller, the controller is connected with the first ends of the first low-noise amplifier and the second low-noise amplifier, the first end of the switch module is connected with the second ends of the first low-noise amplifier and the second low-noise amplifier, and the second end of the switch module is connected with the first antenna and the second antenna; when the switch module is in a first state, the first low-noise amplifier is communicated with the first antenna, and the second low-noise amplifier is communicated with the second antenna; and when the switch module is in the second state, the second low-noise amplifier is communicated with the first antenna or the second antenna. The scheme provided by the invention is used for solving the problem that an antenna is idle due to the fact that a low-noise amplifier connected with a shared single-pole multi-throw switch is scrambled when signals of the same frequency band or similar frequency bands are received.
