Abstract:

The 3D full wave simulation of filters for coupling coefficient extraction is time-consuming and it is difficult to converge the extraction result.A method for extracting coupling coefficient based on the Y parameter of equivalent circuit is proposed and used in the extraction of the aggressive space mapping algorithm to improve the efficiency of filter design.A design example of a 4 cavity coaxial cavity filter is provided.Simulation results are in good agreement with the theory of electromagnetic filter synthesis results,confirming the validity of the proposed method.

Key words: coupled resonator;odd even mode;coupling coefficient;the y parameter
