In an IMPATT diode modulator, a circuit including a free-running oscillator drives the input of a plurality of Schmitt triggers connected in parallel, whose outputs together drive the base of a PNP bipolar transistor connected between positive and negative supply voltages at its collector and emitter through a pulse forming network. The collector voltage of the bipolar transistor drives the gates of a plurality of N-channel V-MOSFET's connected in parallel at their sources and drains between the positive and negative rail voltages.
