ABSTRACT:
A unitary resonator assembly for use in dielectric resonator filters and multiplexers. The unitary resonator assembly comprises a plurality of resonators joined by bridges, where the resonators and bridges are all constructed from a single piece of a dielectric material. The unitary resonator assemblies may be used in conjunction with unitary mounting structures that support a unitary resonator assembly in a filter or multiplexer. Also disclosed are 2-pole, 4-pole, and triplet filters implementing a unitary resonator assembly in conjunction with a unitary mounting structure, and a diplexer implementing a unitary resonator assembly in conjunction with a unitary mounting structure.
