Abstract

The invention provides a radio frequency circuit, a signal interference avoiding method and a terminal device. The radio frequency circuit comprises a first radio frequency transmitting and receivingcircuit, a second radio frequency transmitting and receiving circuit, and a first receiving control circuit; the first radio frequency transmitting and receiving circuit comprises a first radio frequency receiving circuit and a first radio frequency transmitting circuit; the second radio frequency transmitting and receiving circuit comprises a second radio frequency receiving circuit and a secondradio frequency transmitting circuit; the first receiving control circuit is respectively connected to the first radio frequency transmitting and receiving circuit and the second radio frequency transmitting and receiving circuit for turning off the second radio frequency receiving circuit when first transmitting power of the first radio frequency transmitting circuit exceeds a preset power threshold. The radio frequency circuit provided by the embodiment of the invention can detect the strength of the interference signal in real time and correspondingly process the same to trigger the interfered device, which not only effectively avoids the interference, but also ensures the coexistence of the two radio frequency transmitting and receiving circuits to the utmost extent, thereby improvingthe communication capability and user satisfaction.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a radio frequency circuit, a method for avoiding signal interference and terminal equipment. Background technique [0002] At present, some frequency bands defined in 3GPP (Third Generation Partnership Project, Third Generation Partnership Project) overlap or have similar frequency bands with those defined by WiFi (WIreless-Fidelity, Wireless Broadband). When both work at the same time, there will be Very serious interference may even damage related radio frequency devices, resulting in irrecoverable functional failure. [0003] For example, some frequency bands of LTE (Long Term Evolution, long-term evolution) and 5G NR (5 Generation New Radio, 5th generation new air interface) defined in 3GPP are as follows: [0004] LTE / NR frequency band Uplink frequency range Downlink frequency range format LTE B40 2300-2400MHz 2300-2400MHz ...
