Abstract

The invention relates to a microwave pulse generator for generating microwave pulses with a pulse duration in the nanosecond range. The microwave pulse generator includes a pulse generator for generating control pulses of a constant pulse duration and a microwave oscillator generating microwave oscillations. The microwave oscillator includes a transistor amplifier, to which a frequency-determining resonant circuit and an ohmic device for reducing the resonant Q-value are connected in such a way that a control pulse of the pulse generator applied to an input terminal of the transistor amplifier causes the microwave oscillator to produce a microwave oscillation that can be tapped at an output terminal of the microwave oscillator, wherein the microwave oscillation follows at least approximately the temporal course of the control pulse.
