| Abstract: | A conversion model of S-parameter is proposed for plural characteristic impedances in common mode and differential mode.The model is based on Helmholtz Equation and Thevenin's theorem.S-parameters among arbi-trary characteristic impedances and different operating modes could be transformed using analysis method of signal flow graph.This model has made up for the inadequacy of S-parameter measurement for matching networks using the vector Network Analyzer(VNA).Comparison between conversion results of this mo... |
