RECONFIGURED BAND-PASS WAVE-GUIDE FILTER FOR MEASUREMENT OF POWERFUL MICROWAVE RADIATION FREQUENCY Russian patent published in 2011 - IPC H01P1/209 

FIELD: electricity.

SUBSTANCE: device allows examination of microwave radiation frequency changes during one microwave frequency pulse due to small width of pass band Filter consists of length of rectangular waveguide with flanges, four cone-shape stems forming resonant cavity with piston reconfiguring resonator frequency connected with resonant cavity through round hole in wide wall, where there inserted is a bush.

EFFECT: low coefficient of power reflection from resonant cavity at resonant frequency, provision of high electrical strength, possibility of broad reconfiguration by frequency, presence of only one working resonator at desired frequency band, high transmission coefficient at resonant frequency and permanence of relative width of pass band.
