Modified conductor loaded cavity resonator with improved spurious performance

摘要

A microwave cavity (4) has a cut resonator (3) therein that is conductor-loaded. The resonators (5) have a modified shape. Filters made from one or more cavities (6) having cut resonators (5) therein have improved spurious performance over previous filters. A filter can have two conductor loaded resonators (5)in one cavity (10) or a combination of conductor loaded resonators (5)and dielectric resonators (16) in different cavities(7). The cut resonator (3) is out of contact with a wall of the cavity (4). <IMAGE>
