Abstract

The application discloses a radio frequency circuit and electronic equipment, belonging to the technical field of communication. The invention can solve the problem that each component in the existing radio frequency circuit is easily damaged or damaged due to the influence of a high-power radio frequency signal. The radio frequency circuit includes a transceiver, a transmitting circuit, a first receiving circuit, a second receiving circuit, a first single-pole double-throw switch, a power detection circuit and an antenna. The power detection circuit in the radio frequency circuit realizes the timely detection of the power of the radio frequency signal received by the antenna, and can transmit the detected high-power radio frequency signal to the ground with the power greater than the preset power threshold, avoiding high-power The radio frequency signal enters other components of the receiving circuit and the transceiver connected to the receiving circuit, thereby avoiding damage or damage to various components in the radio frequency circuit by the high-power radio frequency signal, and realizing the effective protection of the radio frequency circuit in a high-power environment Effect.

Description

technical field [0001] The present application belongs to the technical field of communication, and in particular relates to a radio frequency circuit and electronic equipment. Background technique [0002] At present, in the integrated circuit module of electronic equipment, the receiving path for receiving radio frequency signals lacks an effective protection mechanism. When high-power radio frequency signals enter the antenna of electronic equipment, some components in the receiving path that do not have the ability to withstand high power are easily damaged. Damaged or destroyed, so that the electronic equipment has poor signal or even can no longer receive and transmit radio frequency signals. Therefore, how to better protect the receiving path of the electronic device so as to adapt the electronic device to the current complex environment has become an urgent problem to be solved. [0003] At present, the commonly used method of protecting the receiving path of electr...
