Time domain modelling of microwave systems and subsystems

Abstract

A new method of modelling non-linear microwave system and subsystem is presented. Non-linear models of the subsystem are identified and then combined to solve the entire system. Throughout the procedure time domain modelling and simulation is used but frequency domain characteristics can also be obtained. Models of non-linear subsystems are identified from time domain measurement which require less measurement time compared to frequency domain measurement. Black box models are used instead of equivalent circuits. The identified models are time domain transfer functions and this offers flexibility and saving in the amount of data stored for each model.
