Extraction of coupling parameters for microwave filters: determination of a stable rational model from scattering data

We present a method to derive a rational model from scattering data for electrical parameter extraction. Unlike other methods, the stability and the MacMillan degree of the rational approximation are guaranteed. In order to improve the usability of our method in computer-aided tuning, we also present an algorithm performing automatic reference plane adjustment. Results obtained on a 10th order dual mode IMUX filter are presented.
