Abstract
The present invention provides a high frequency dielectric filter which can realize high stability, the least loss of functionality, and mass-productiveness. In a high frequency dielectric filter adopting a TM mode, a resonator fixing plate,is used for fixing a dielectric resonator,and a case,and hence, they are firmly fixed both in the longitudinal direction and the lateral direction of the resonator. Accordingly, a high frequency dielectric filter which is stable against vibration and impact is provided.
