PROTECTIVE CYCLOTRON UNIT CHARACTERIZED IN ENHANCED OPERATING FREQUENCY BAND Russian patent published in 2008 - IPC H02H7/12 H01J23/36 H01J25/00 

FIELD: high-frequency electronics; devices for protecting microwave radio receivers of radar stations against heavy power fluctuations in superhigh and extremely-high frequency bands.

SUBSTANCE: proposed device has electron gun, input and output electrodynamic structures unidirectionally coupled through electron flow and separated by means of diaphragm with hole to pass electron flow, as well as collector. Homogeneous magnetic field is oriented to electron flow direction. Each electrodynamic structure is formed by electromagnetically coupled and series-connected resonators. Unidirectional coupling of electrodynamic structures through electron flow is provided only between resonators of these structures closest to each other and diaphragm is disposed in-between.

EFFECT: extended operating frequency band.
