摘要： A metallized dielectric waveguide filter includes an upper metallized dielectric waveguide having a plurality of upper resonant cavities, the upper metallized dielectric waveguide comprising an upper dielectric block having metallized outer walls, and a lower metallized dielectric waveguide having a plurality of lower resonant cavities, the lower metallized dielectric waveguide comprising a lower dielectric block having metallized outer walls. A first of the upper resonant cavities is operatively connected to a first of the lower resonant cavities via at least one coupling window. A first slot having metallized walls is provided in a portion of the upper dielectric block that is part of the first of the upper resonant cavities.

摘要： Filters include a housing having a top wall, a bottom wall and one or more side walls that define an internal cavity; a plurality of resonators that are mounted within the internal cavity with a first space provided between a pair of adjacent resonators; and a coupling-tuning element mounted on one of the walls of the housing. The coupling-tuning element comprises one or more solid dielectric materials and is capable of extending into the first space to tune the coupling characteristics between the pair of adjacent resonators.
