TM medium resonator and method for realizing the same, TM medium filter

摘要

The present invention provides a method for implementing a TM dielectric resonator, and the method includes: a dielectric resonant column component with a metal connecting plate is machined; a metal cavity with an opening at one end is machined; the metal connection plate of the dielectric resonant column component is fastened to the inner wall of the metal cavity by a screw; the opening of the metal cavity is covered with a prefabricated cover plate; and a prefabricated tuning screw is screwed from the cover plate into the metal cavity. According to the method for implementing the TM dielectric resonator, the machining process is simple, and the machined TM dielectric resonator is small in volume, excellent in performance and high in operational reliability. An embodiment of the present invention further provides a TM dielectric resonator machined by the method above and a dielectric filter formed by one or more TM dielectric resonators.
