Advanced coupling matrix synthesis techniques for microwave filtersIEEE TRANSACTIONS ON MICROWAVE THEORY AND TECHNIQUES, VOL. 51, NO. 1, JANUARY 2003 1 Advanced Coupling Matrix Synthesis Techniques for Microwave Filters Richard J. Cameron, Fellow, IEEE Abstract―A general method is presented for the synthesis of the folded-configuration coupling matrix for Chebyshev or other filtering functions of the most general kind, including the fully prescribed finite-position transmission canonical case, i.e., zeros in an th-degree network. The method is based on the ” transversal network coupling matrix, which is able “ to accommodate multiple input/output couplings, as well as the direct source……
