hi i'm also working on pulse generators.i want to built it using solid state relays and mercury wetted relay. i'm looking for a fet which is rated for 500v,5Amp, rise and fall times below 5ns. does anyone have an idea about which fet suits my application and also i want to know the driver details.Does anyone know which manufacturer still produces mercury wetted reed relay capable of generating 5ns high voltage pulses? Thx
thank u for helping.........
