'Engine-Block', Dual Mode Dielectric Resonator Loaded Cavity Filter with Nonadjacent Cavity Couplings

摘要

A degenerate mode in a dielectric resonator loaded cavity is utilized to realize a flat, miniature, high performance bandpass filter in side coupled, "engine block" configuration. A novel way of providing coupling between nonadjacent electrical cavities by an interchangeable iris-probe combination is employed to achieve high performance elliptic function response.
