BAND-PASS MICROWAVE FILTER Russian patent published in 2021 - IPC H01P1/219 

FIELD: electricity.

SUBSTANCE: invention relates to microwave equipment and can be used in transmitting devices for filtration of microwave signals with high level of passing average power. Band-pass filter (BPF) comprises quarter-wave resonators galvanically connected to each other by means of side surfaces, made on the basis of coaxial ceramic lines (CCL) of round section, each resonator and communication capacitors are made as one structural element and separated from the resonator by a gap in metallization of outer surface CCL and are made in the form of capacitors, plates of which are inner conductors and external surfaces of section CCL from gap to open end CCL. Resonators are installed on pins in metal housing. Dielectric rods are fitted in open CCL ends butt to housing pins. Housing is installed on horizontal surface of base made in the form of angle, to vertical surface of which dielectric rods are attached.

EFFECT: increased level of passing average power, improved strength characteristics, manufacturability in assembly and adjustment.
