Synthesis of cascaded lossless commensurate lines

Abstract

A scattering transfer matrix factorization based algorithm for cascaded lossless commensurate line synthesis is presented. The characteristic impedances of the extracted commensurate lines and the reflection factors of the remaining networks are formulated in terms of reflection factor coefficients of the whole circuit. There is no need to use root search routines so as to cancel common terms to get degree reduction. The formulation. of the method is explained. and an example is included to illustrate the implementation of the synthesis algorithm.
