A Compact Pulse Magnetron Microwave Generator Based on a Solid-State Switch

A pulsed magnetron system generating high-energy microwave pulses with a frequency of 400 Hz and an average power of 0.5 kW is described. To generate a magnetron current pulse, a circuit with 12 identical transistor modules with an operating voltage of 800 V, which are connected in series to the primary winding of a high-voltage pulse transformer with a transformation ratio of 3.5, is used. Thus, a voltage pulse with an amplitude of up to 26 kV and a 25-A current with an adjustable duration of 100–500 ns is formed. Experimental data of the system operation into the pulsed microwave magnetron and an equivalent load are presented.
