摘要

A filter (10) including first and second resonators (12) and a coaxial cable (14) connecting the resonators (12). Also, the filter (10) including a housing (16) and stepped impedance resonators (12) wherein the high impedance portions (40) of the stepped resonators (12) are integral with the housing (16). Also, methods of manufacturing the filters (10).
