KLYSTRON TYPE SUPERHIGH FREQUENCY DEVICE Russian patent published in 2009 - IPC H01J25/10 

FIELD: physics; radio.

SUBSTANCE: invention concerns electronic engineering, in particular to the electrovacuum microwave devices intended for reception of microwave capacity on two multiple frequencies also can be used, for example, in the accelerating technics, radar-location, radio countermeasure. The klystron-type microwave device contains the cylindrical target double-gap cavity (TDC), adjusted on an antiphase kind of fluctuations with an operating frequency co and on an inphase kind of fluctuations with an operating frequency 2ω. The device for microwave energy output contains, at least, two square-topped wave guides, connected with the TDC accordingly through the first and second coupling windows. The first coupling window is located between face walls of the target double-gap cavity equally spaced from them and allocated from a communication slot in a TDC conducting plate. The second coupling window is located from a continuous site of the conducting plate and located between the conducting plate and one of face walls of the output TDC opposite to corresponding high-frequency spacing. The sizes of wide walls of square-topped wave guides are chosen from the set conditions. The microwave device can contain a band elimination filter connected to the second square-topped wave guide.

EFFECT: increase of efficiency and expansion of functionality of the microwave device.
