Abstract :
A new parameter extraction procedure for symmetric coupled-resonator filters is presented. Closed form recursive formulas are derived for the synthesis of all the filter parameters from known zeros and poles of the even- and odd-mode input impedance functions. The simple and straightforward procedure can eliminate complicated optimization routines and have extensive applications in design and tuning of filters.
