Filed: 1992-01-14
Abstract: PURPOSE:To provide a sufficient conversion efficiency by using a CaAsMESFET and setting its gate bias point in the vicinity of the point where the mutual conductance is switched to a certain area from the increase against the increase of the gate voltage. CONSTITUTION:A pulse dope structure GaAsMEFET 1 is used as the active device of a mixer circuit. An input circuit 2 is connected to the gate of the FET 1, and an output circuit 3 is connected to the drain.

Consequently, it is necessary to operate the circuit at gate bias points where a mutual conductance gm is nonliner for a gate voltage Vg. The gate bias point where the input impedance is not large changed for the fluctuation of the gate voltage due to a large amplitude of a local oscillation signal is searched from these gate bias points meeting this condition and is set. Thus, the sufficient conversion efficiency is obtained even if the change of the input impedance is small.
