HIGHER FREQUENCIES WAVEGUIDE FILTER Russian patent published in 2014 - IPC H01P1/20 

FIELD: electricity.

SUBSTANCE: filter represents a section of a rectangular waveguide with flanges and diaphragms of the preset height in-built into both narrow walls of the waveguide and one wide wall of the waveguide; in a cut nonradiating slot on the opposite wide side of the waveguide there is an in-built diaphragm with setting depth reconfigurable mechanically, which is intended for frequency change in the filter section.

EFFECT: provision of coarse measurement of powerful microwave radiation frequency in SHF devices and suppression of out-of-band and parasitic oscillations.
