  • Dielectric tube loaded metal cavity resonators and filters
    Patent number: 6535086
    Abstract: Dielectric tube loaded metal cavity resonators and filters having a dielectric tube resonator extending substantially the full height of the metallic cavity are disclosed herein. The resonators and filters achieve low insertion loss in a size substantially smaller than conventional dielectric loaded resonators for equivalent quality factors. The dielectric tube resonators may be used with coaxial resonators to provide mixed resonator filter constructions.
