MICROWAVE CAVITY RESONATOR Russian patent published in 2006 - IPC H01P7/06 H01J23/207 

FIELD: microwave electronics.

SUBSTANCE: proposed inductively frequency tuned microwave cavity resonator that can be used for O-type devices, such as klystrons, has inductive frequency tuning component made in the form of adjusting screw disposed in threaded through hole in resonator narrow wall; it contacts threaded sections of resonator wide walls at least on part of their length. Thread in sections of resonator wide walls is extension of that in hole of resonator narrow wall. Threaded sections of opposing wide walls can be also made in the form of projections facing one another and symmetrically disposed relative to resonator axis. Resonator is easily tuned and provides for repeatability of results and absence of stray electron secondary resonance.

EFFECT: enhanced operating-frequency tuning range, resistance to mechanical impacts, and reliability; simplified design.
