ABSTRACT:
A self-excited mixer circuit using a dual gate type field effect transistor, in which an inductive impedance element inductive with respect to a local oscillation frequency, a first capacitive element and a second capacitive element are connected across the drain and the second gate, across the drain and the source, and across the second gate and the source, respectively, of field effect transistor to constitute an oscillation circuit across the drain and the second gate of transistor, so as to derive an intermediate frequency signal from the drain of the transistor in response to the application of the radio frequency signal to the first gate of transistor.
