Patent ID: 7183881

Claim:
A dielectric resonator circuit comprising: a plurality of resonators, each comprising a body formed of a dielectric material, said body having a first end and a second end, said body varying in cross-sectional area between said first and second ends; wherein said plurality of resonators are positioned relative to each other such that a field generated in each resonator couples to an adjacent resonator; wherein each of a first and second of said plurality of resonators are adjacent to a third of said plurality of resonators, wherein said first and second resonators are alternate resonators positioned such that a field in one of said first and second resonators cross-couples directly to the other of said first and second resonators, an adjustable conductive member capable of being positioned at least partially between said first and second resonators to affect cross-coupling between said first and second resonators; and a mounting member coupled to said third resonator for positioning said third resonator, wherein said mounting member and said conductive member are coaxial, wherein said mounting member is a hollow mounting cylinder having an internally threaded surface and an externally threaded surface; and wherein said conductive member is a conductive cylinder having an externally threaded surface for mating with the internally threaded surface of said hollow mounting cylinder.
