Computer-Aided Design and Analysis of Different Configurations of Singly - Balanced Microstrip Diode Mixers Using the Modified MSDES and ADS Packages

Abstract—The aim of this paper is to introduce the computer aided design and analysis of different configuration of singly-balanced Microstrip diode mixers using the recent MSDES program developed by the author and the recent ADS package. The design stages of the Microstrip Mixers including the design of hybrid couplers, Design of matching circuit that matches the diode input impedance to the coupler, and design of Lowpass filter that passes the IF output signals are introduced. The Teflon substrate with substrate parameters er = 4.3, H = 1.35 mm and T = 0.035 mm is used for the mixer circuit design and analysis. The ADS layouts and the applications of the designed Microstrip mixers are presented.
