RADIO FREQUENCY RECEIVER

WIPO Patent Application WO/2021/102916

A1

Provided in the embodiments of the present application is a radio frequency receiver, relating to the technical field of electronics, and used for realizing precise gain adjustment of the radio frequency receiver. The radio frequency receiver comprises: a trans-conductance amplifier (GM) used for receiving a radio frequency signal; a first carrier amplification branch and a second carrier amplification branch coupled with an output end of the trans-conductance amplifier, wherein the first carrier amplification branch is used for outputting a first carrier signal, and the second carrier amplification branch is used for outputting a second carrier signal, and both the first carrier amplification branch and the second carrier amplification branch comprise gain adjustment modules, which are used for respectively adjusting the gains of the first carrier signal and the second carrier signal; each gain adjustment module comprises a shunt pipe and a compensation pipe; the shunt pipe comprises at least two transistors; one end of the transistor of the shunt pipe is coupled with a power supply; and one end of the transistor of the compensation pipe is coupled with a load.
