Abstract
The utility model discloses a broadband receiver supporting a handheld air control station. The broadband receiver includes an antenna module, a frequency mixer A, a frequency mixer B, an AGC amplifying circuit and a detector. The output terminal of the antenna module is connected with the frequency mixer A through a bandpass filter A, an attenuator, a low noise amplifier and a bandpass filter B successively. The output terminal of the frequency mixer A is connected with the frequency mixer B through a first intermediate frequency filter A, a first intermediate frequency amplifier and a first intermediate frequency filter B successively. The output terminal of the frequency mixer B is connected with the AGC amplifying circuit through a second intermediate frequency amplifier A, a broadband crystal filter and a second intermediate frequency amplifier B. The output terminal of the AGC amplifying circuit is connected with an input terminal of the detector. The broadband receiver is high in integration degree, good in anti-interference capability and high in consistency, and has a frequency selecting function. High-density integration is adopted, so that deviation due to device dispersion can be avoided. And the broadband receiver is high in reliability and precision.
