High performance modulators using MOSFETs

Power metal-oxide-semiconductor field effect transistors (MOSFETs) are emerging as a desirable alternative to more established switching technologies in high-voltage modulators. Available single-die devices are specified to control over 50 kW of peak power. A simple stacking arrangement is presented which can supply output pulses of 5 kV or greater into low-impedance loads at high repetition rates and with low jitter. The basic circuit module is configured without output transformers and provides a flexible floating-deck high-voltage switch function amenable to thick-film hybrid packaging
