Abstract

The invention relates to a frequency and capacitance coupling double-tuned resonance structure and an application thereof, and a filter comprising the structure. The structure comprises a body made ofa solid dielectric material, blind grooves are arranged in the body, and at least one blind groove can be used for debugging a resonant frequency and capacitive coupling at the same time. The invention provides a resonant frequency and capacitance coupling double-tuning structure which can be simultaneously realized through a single blind groove, and a dielectric waveguide filter comprising the structure, which are convenient for later debugging, are verified to be effective and have good performance.

Description

technical field [0001] The invention relates to the technical field of communication equipment components, in particular to a frequency and capacitive coupling double tuning structure for a dielectric waveguide filter. [0002] technical background [0003] Dielectric waveguide filters are the mainstream choice for filter components in domestic 5G and future mobile communication base stations. The dielectric waveguide filter is mainly composed of multiple solid dielectric resonators, and the filtering performance is realized through the coupling before the resonators. Usually, each dielectric resonator can be tuned through a frequency tuning blind hole on it, and the coupling between resonators can be tuned by setting a coupling window or a coupling tuning blind hole between two resonators, wherein the coupling window realizes Inductive coupling is achieved, and capacitive coupling is achieved by coupling tuning blind holes. The introduction of capacitive coupling can reali...
