Abstract

A microwave mixer circuits has been designed and fabricated, having frequency range of 2 GHz- 4 GHz, with optimum operating point at 3 GHz. The underlying theory of rat-race coupler was used to achieve frequency up-conversion and down-conversion process with the help of a nonlinear element - Schottky diode. The simulation of both the rat-race coupler and the mixer circuit has been done with Agilent Advanced Design System (ADS) software, and the fabricated mixer circuit has been tested using Vector Spectrum Analyzer (VSA). The measured results of the mixer has shown perfect consistency with the simulated outputs.
