Abstract :
Starting from the "cascode" model of the dual gate microwave MESFET an analysis of its performance as a mixer is carried. In this approach, the modulation of the transconductance of the second FET as well as the "drain" resistance of the first FET by the local oscillator voltage are taken into consideration. The obtained relation for the conversion gain permits the optimization of dual-gate MESFET mixers performance.
