Abstract

The invention discloses a TM dielectric resonator realizing method. The TM dielectric resonator realizing method comprises the following steps of manufacturing a dielectric resonance column assembly provided with a metal connecting plate, wherein a connecting stud is manufactured on the metal connecting plate; manufacturing a metal cavity with one open end; utilizing the connecting stud to screw the dielectric resonance column assembly provided with the metal connecting plate into an inner wall of the metal cavity; using a pre-fabricated cover plate to seal an opening of the metal cavity; and screwing a pre-fabricated tuning screw into the metal cavity from the cover plate. The TM dielectric resonator realizing method is simple in manufacturing technology, and a manufactured TM dielectric resonator is small in size, good in performance and high in reliability. The invention further provides the TM dielectric resonator manufactured by means of the method and a dielectric filter consisting of one or more TM dielectric resonators.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a TM dielectric resonator, a realization method thereof and a TM dielectric filter. Background technique [0002] When the electromagnetic wave propagates in a material with high dielectric constant, its wavelength will become shorter. Taking advantage of this characteristic, dielectric materials can be used instead of traditional metal materials. Under the same index, the volume of the filter can be reduced. Research on dielectric filters has always been a hot spot in the communication industry. Filters are important components of wireless communication products, and dielectric filters are of great significance to the miniaturization of communication products. [0003] Such as figure 1 As shown, generally, a TM mode dielectric resonator is mainly composed of a dielectric resonance column 103 , a sealing cover 102 , a tuning screw 101 , and a metal cavity 104 . Wherein, ...
