Abstract
The invention relates to the technical field of microwave electronics, and in particular to a frequency conversion channel module. The frequency conversion channel module includes successively a first mixer circuit, an intermediate frequency circuit, a first attenuator, a first amplifier, an equalizer, a first band-pass filter, a first power divider, and a second attenuator. The intermediate frequency circuit successively includes a second band-pass filter, a second amplifier, a first [phi] attenuator, a third band-pass filter and a second power divider, and also a detector. The detector is connected to the first power divider, such that the frequency conversion channel has increased anti-interference capability.
