Claim 10:
11. A metallized dielectric waveguide filter, comprising:
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;
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,
wherein a first of the upper resonant cavities is operatively connected to a first of the lower resonant cavities via at least one coupling window, and
wherein 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,
wherein the upper metallized dielectric waveguide further comprises metallized vias that extend through the upper dielectric block to define the upper resonant cavities, and the lower metallized dielectric waveguide further comprises metallized vias that extend through the lower dielectric block to define the lower resonant cavities.
