Abstract

The invention provides a radio frequency circuit, terminal equipment and a circuit control method. The radio frequency circuit comprises: a first radio frequency receiving and transmitting module, at least one first radio frequency receiving path and a second radio frequency receiving and transmitting module; each first radio frequency receiving path comprises a first antenna, a first switch module, a first filter and a first amplifier; the first antenna is connected with a first contact of the first switch module; a second contact of the first switch module is grounded, a first movable arm of the first switch module is connected with a first end of the first filter, a second end of the first filter is connected with an input end of the first amplifier, and an output end of the first amplifier is connected with a receiving end of the first radio frequency transceiving module; the first switch module is used for controlling the connection state of the first movable arm and the first contact and the connection state of the first movable arm and the second contact. According to the embodiment of the invention, the possibility of interference between antennas connected with different radio frequency transceivers can be reduced.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a radio frequency circuit, terminal equipment and a circuit control method. Background technique [0002] With the rapid development of terminal technology, terminal equipment has become an indispensable tool in people's life, and brings great convenience to all aspects of users' life. There may be many radio frequency transceivers in the radio frequency circuit of the terminal device, and different radio frequency transceivers are connected to different antennas. For example, it can be connected with an antenna for transmitting radio frequency signals and an antenna for receiving radio frequency signals, and can receive or transmit radio frequency signals. [0003] However, in the prior art, there is a relatively high possibility of interference between antennas connected to different radio frequency transceivers.
