ABSTRACT:
A dual balanced mixer frequency converter is disclosed which provides a low conversion loss by reactively terminating one of the leads on a combiner circuit such that all the image frequency signal power and/or part of the reflected receiver power is returned to the mixer. If this termination appears reactive at the image frequency response looking out from the mixer diode terminals, it will also reduce the noise appearing in the IF output signal.
