Abstract

The invention provides a microwave frequency conversion circuit and a frequency converter, wherein the microwave frequency conversion circuit includes a radio frequency amplification module, a highly integrated control module, a crystal oscillator module and a voltage stabilization module; The crystal oscillator module outputs the local oscillator signal to the control module, and the control module mixes the amplified horizontal polarization signal, the amplified vertical polarization signal and the local oscillator signal into an intermediate frequency signal and outputs it to the receiver. The module also adjusts the frequency of the local oscillator signal according to the control signal, and the voltage stabilizing module adjusts the voltage of the voltage signal to a preset value to supply power to the control module. The invention connects the radio frequency amplification module, the crystal oscillator module and the voltage stabilizing module through a highly integrated control module to form a microwave frequency conversion circuit with a microwave frequency conversion function. The circuit structure is simple and the peripheral circuits are few, which can effectively reduce the interference between electronic components.
