摘要
A microwave mixer circuitry having a plurality of microwave signal input terminals, a local oscillator for outputting a local oscillation signal for the purpose of generating an intermediate frequency signal from microwave signal input by microwave signal input terminals, a plurality of field effect transistors ("FET'') for converting frequency, of which gates are input with the microwave signal input from microwave signal input terminals, and of which drains are input with an output of local oscillator, a plurality of gate voltage control circuitries for controlling gate voltages of FET's thereby causing one of FET's to perform nonlinear operation while turning off the another of FET's at the same time, and an intermediate frequency signal output terminal for outputting the intermediate frequency signal produced by the nonlinear operation of one of the FET's.
