Powerful RF electro-vacuum devices for industrial, scientific and medical applications

The report examines the most common microwave vacuum electronic devices (triode, tetrode, diacrode, klystrons, IOT, magnetron, gyrotron, BWO). It noted the main features of their work. The limiting parameters and characteristics of these electronic devices made to data. The estimation of the prospects of the use of ISM-technologies in the short-range microwave. It is noted that in addition to the use of traditional instruments (magnetrons and klystrons) certain application prospects in the frequency range up to 2 GHz have multibeam IOT, and in the range above 10 GHz have a low-voltage multibeam monotron generators.
