摘要
It is usually proven difficult to accurately simulate the microwave and RF circuits. This paper intends to present an easy method for modeling and simulation of nonlinear active microwave circuits using Ansoft Serenade 8.0 Design Environment. Starting with some simple circuits (MESFET mixer circuits, GaAs BJT Feedback Microwave Amplifier), the authors describe the main principles of simulating RF and microwave circuits and a new method for modeling the active RF devices (such as MESFET and GaAs BJT Transistors) in order to obtain the best results for multitone nonlinear analysis. The new proposed method also covers the stability problems, based on the Nyquist stability criteria, and the matching impedance Smith plots of the RF circuits.
