Analysis and Optimization of a Class of Two-Diode Microwave Mixers by Means of Their Equivalent Single-Diode Mixer Models

A class of two-diode microwave mixers (called "magic T") is defined and its equi valent single-diode models are developed. The models are used at nonlinear. linear and noise steps of the analysis to predict mixers properties and draw general conclusions. A "crossbar" mixer example illustrates the paper.
