Wireless microphone receiver with high linearity and high sensitivity

The utility model relates to the technical field of wireless microphone receivers, in particular to a high-linearity and high-sensitivity wireless microphone receiver, which comprises a fifth control unit, a first control unit, a second control unit, a third control unit and a fourth control unit. The first control unit, the second control unit, the third control unit and the fourth control unit are sequentially connected through RF signals. The fourth control unit is connected with the fifth control unit through an IF1 signal. A passive mixer, a high IIP3 radio frequency amplifier and attenuator architecture, and front and rear two-stage narrowband surface acoustic wave filters are adopted; the problems that due to the fact that linearity of a traditional wireless microphone receiver is too low, third-order intermodulation interference of the receiver is too large when dozens of transmitters are used at the same time, sound interruption is caused, and the use distance is shortened are solved. 本实用新型涉及无线麦克风接收机
