Abstract
A coaxial resonator is provided. The coaxial resonator has a first side and a second side, the coaxial resonator comprising a dielectric disc having a first surface, a second surface and a hole, wherein the second side of the coaxial resonator is connected to the first surface of the dielectric disc, wherein the coaxial resonator further comprises a conductive element connected to second surface of the dielectric disc. A filter comprising a housing, comprising a lid/cover and a chassis having one or more cavities adapted for receiving a coaxial resonator is also provided.
