High speed pulse generator

[vahidsh]

Hi dear all,
I wanna design a pulse generator that can generate pulses with 1-2 ns duration and 1ns rise/fall time and the repetition rate of pulses is about 1-5KHz( the circuit shold be control for repetition rate for example by fpga the repetition rate of pulse generator can change 1-5 KHz). This pulses should be high voltage(10KV).
Now i have a question that these spec for the pulse generator is achievable by solid state technology?

The speed and voltage range can be achieved by cascaded MOSFET and particularly BJT avalanche switches. The latter can only switch fast on, so they are usually implemented as transmission line pulsers.

Simultaneous triggering of the cascaded switches with < ns skew is challenging.

usually special relays are used to get the fast rise times you are seeking, such as in ESD guns, used for ESD immunity testing...

What will be the load capacitance and resistance?. As you are dealing with a very high Dv/Dt the current will be very high, unless there is no load. Likewise ringing of the pulse due to board wiring and supply decoupling will be a great problem.
