Abstract

The invention provides a resonator, a filter, a duplexer, a multiplexer and communication equipment. The resonator comprises a resonant cavity body; the resonant cavity body is provided with a resonant cavity and an opening end; the resonator also comprises a deformation cover plate covering the opening end and connected with the resonant cavity body, a resonant tube located in the resonant cavity, an adjusting mechanism arranged on the deformation cover plate; a groove is formed in the side, back on to the resonant cavity, of the deformation cover plate; the adjusting mechanism is arranged in the groove and used for providing acting force in the axial direction of the resonant tube, so that the bottom of the groove is continuously deformed, and the distance between the deformation cover plate and the resonant tube can be adjusted. According to the resonator, filter, duplexer, multiplexer and communication equipment of the invention, the intermodulation performance and the high-power performance of a product can be improved, the production passing rate of the product can be improved, the rejection rate and the maintenance cost of the product are reduced, and the market competitiveness of the product is improved.

Description

technical field [0001] The present invention relates to the technical field of communication equipment, and more specifically, relates to a resonator, filter, duplexer, multiplexer and communication equipment. Background technique [0002] As a frequency selective device, cavity filters are widely used in the field of communication, especially in the field of radio frequency communication. In the base station, the filter is used to select the communication signal and filter out the clutter or interference signal outside the frequency of the communication signal. [0003] A traditional cavity coaxial filter mainly includes a cavity, a cover plate, a resonant rod, a tuning screw, a coupling screw, a window and a connector. Among them, the cavity, cover plate, resonant rod and tuning screw constitute the filter resonant cavity, the tuning screw is installed on the cover plate through the thread structure, and the distance between the tuning screw and the resonating rod is chan...
