Claim 11:
12. A metallized dielectric waveguide filter, comprising:
an upper metallized dielectric waveguide having a first upper resonant cavity, a last upper resonant cavity, and at least one intermediate upper resonant cavity that is positioned between the first upper resonant cavity and the last upper resonant cavity, the upper metallized dielectric waveguide comprising an upper dielectric block having metallized outer walls;
a lower metallized dielectric waveguide having a first lower resonant cavity, a last lower resonant cavity, and at least one intermediate lower resonant cavity that is positioned between the first lower resonant cavity and the last lower resonant cavity, the lower metallized dielectric waveguide comprising a lower dielectric block having metallized outer walls,
wherein the last upper resonant cavity is operatively connected to the first lower resonant cavity via a first coupling window, a second coupling window and a third coupling window, and
wherein the first coupling window extends generally transversely across an interface between the last upper resonant cavity and the first lower resonant cavity, and the second and third coupling windows extend generally longitudinally across the interface between the last upper resonant cavity and the first lower resonant cavity, and the first coupling window is the only coupling window that extends generally transversely across the interface between the last upper resonant cavity and the first lower resonant cavity.
