I have been asked to try to build a driver for a photoconductive switch. It has to run at 40MHz, sine or square would be O.K., and be phase locked to a pulse train. The voltage needs to be variable, though not with great precision, and needs to be stable only for the few fS a laser pulse hits the switch. So far so good: I can do that. My problem is the switch needs at least +/- 100 volts drive and preferably +/- 200 volts. The switch looks like about 2pF, only, so that may help.
Does anyone have any ideas about the kind of circuitry which might drive such voltages in this application?
