Claim 0:
1. A metallized dielectric waveguide filter, comprising:
an upper metallized dielectric waveguide having a plurality of upper resonant cavities that extend along a longitudinal axis, 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 longitudinally-extending 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.
