PRC-77 A12 Second Mixer Module

A12 Second Mixer Circuit Module (Receiver)

The Circuit Module A12 is the second mixer stage for the PRC-77 / RT-841 radio set. It is a core assembly within the receiver circuit, responsible for down-converting the signal to the final intermediate frequency.

A defect in the A12 often leads to a complete loss of reception or severe signal distortion, as the necessary frequency conversion in the receiver path is impaired.
