RESONATOR BAND-PASS MICROWAVE FILTER Russian patent published in 2019 - IPC H01P1/20 

FIELD: radio equipment.

SUBSTANCE: invention relates to radio engineering, in particular to filters. Resonator bandpass microwave filter contains external spheres, internal elements, inductive pin, cylindrical connecting pins and coupling elements in the form of coaxial lines, two resonators, metal inserts and coupling elements. Resonators are made passable and spherical, in the center of each of which the metal insert in the form of a metal core formed by a sphere with a thin metal washer around its perimeter is located, and both cores along the central axis are connected with a cylindrical pin through the opening formed by the intersection of external spheres. Communication elements are made in the form of standard coaxial transmission lines, the internal conductors of which are coupled with the metal core.

EFFECT: simplicity of design, reliability, small size.
