Traditional Marx generators have been primarily reserved for energy storage and pulse-charging sources. However, recent work has demonstrated the Marx generator’s effectiveness in delivering ultra-short impulses at very intense power levels. This paper discusses two very compact Marx generators capable of delivering voltage pulses of several hundred kV, durations of several nano-seconds to 10’s of nanoseconds, and risetimes as fast as 200 ps. Performance of these generators will be discussed as well as radiation results with the generator directly driving a TEM horn antenna. Further discussion will be made toward the application of the Marx generator driving various microwave devices including the Backward Wave Oscillator.
