Abstract

The invention discloses a single-resonance and double-resonance mould structure of a TM (Transverse Magnetic) dielectric resonator, comprising a metal cavity box, a metal cover plate and a TM medium resonance rod, wherein upper and lower end faces of the TM medium resonance rod are respectively connected with the metal cover plate and the bottom face of a metal cavity box resonance cavity; the height of the TM medium resonance rod is slightly higher than the depth of the metal cavity box resonance cavity; the metal cover plate is provided with an elastic compaction region which can keep plane contact with the upper end face of the TM medium resonance rod; the elastic compaction region is contained in a region surrounded by closed type grooves arranged in the metal cover plate; after the closed type grooves are axially pressed on the elastic compaction region, the elastic compaction region does translational movement up and down under the deformation of the closed type grooves through the extending or compression of groove openings and the partial deformation generated by limited bending of the bottom edges of the grooves, so that the good contact between the metal cover plate and the metal cavity box and among the TM medium resonance rod, the metal cover plate and the bottom face of the metal cavity box resonance cavity is kept. The single-resonance and double-resonance mould structure has a simple stricture and can effectively solve the problem generated by a fixing manner of a traditional technology.

Description

technical field [0001] The invention relates to the technical field of the wireless communication industry, in particular to the application technology of a radio frequency cavity filter using a TM dielectric resonator, specifically a single and double resonant mode structure of a TM dielectric resonator. Background technique [0002] At present, the development of wireless communication technology has put forward higher and higher requirements for mobile communication systems, and filters made of traditional metal materials can no longer meet the new technical requirements. Some new materials have replaced traditional metal materials in cavity filters. Dielectric resonators use some outstanding characteristics of dielectric ceramic materials to replace traditional metal material resonators. Dielectric ceramic materials have the characteristics of low loss, high dielectric constant, small frequency temperature coefficient and thermal expansion coefficient, and can withstand...
