WAVEGUIDE DUAL-MODE MICROWAVE FILTER Russian patent published in 2024 - IPC H01P1/207 

FIELD: radio engineering.

SUBSTANCE: invention relates to microwave engineering and can be used as a waveguide band-pass filter of ultrahigh frequencies. A waveguide microwave filter containing resonators operating on modes TM110, between which diaphragms are located. At that, waveguide microwave filter, made even-link, contains supplying waveguides, between which the structure with alternation of U-shaped resonators with transverse splitting and diaphragms is applied, at that, the said resonators are made with possibility to be supplied either in the splitted part, or in the unsplit, and said supply waveguides, which are connected to corresponding U-shaped resonators and docked with corresponding diaphragms, are made in the form of input and output metal sections of waveguides of identical cross-sections.

EFFECT: improved frequency selectivity of the filter.
