A true elliptic-function filter using triple-mode degenerate cavities
Abstract
A new iris structure that is capable of providing three independent intercavity couplings is presented. The relevant design details of a triple-mode elliptic-function filter are given. The experimental performance of a sixth-order triple-mode filter using this new coupling iris is presented. The results indicate that excellent control of the degenerate mode excitation and intercavity mode coupling is possible. The filter has reduced size and weight, and provides a much larger Q than the corresponding dual-mode counterpart.
