A high power pulse waveform generator for amplifying an input pulse signal has an a.c. coupled amplifier with d.c. negative feedback. An output stage of the a.c. coupled amplifier has a pair of opposite polarity, high power transistors coupled in series between a high power voltage source and a reference power rail, such as ground, with the junction between the transistors being an output terminal. An input stage receives the input pulse signal and provides a bias during a quiescent state of the input pulse signal to the output stage so that the output terminal is clamped to the reference power rail regardless of any d.c. offset in the input pulse signal. The input stage a.c. couples the pulse of the input pulse signal to the output stage to provide the high power pulse waveform at the output terminal. The output terminal is d.c. coupled to the input terminal to provide negative feedback so that the shape of the high power pulse waveform follows the shape of the input pulse signal.
