20kHz Q switch driver

 20kHz "Q" Switch Driver

This compact pulser is Designed as a "Q" Switch driver, delivering around 950 volts into up to a 100pf load at 20kHz. The pulse width can be adjusted from around 10ns to 50ns. Risetime is load dependent but typically in the range 5 to 10ns. Runs from a 9 volt supply.

This driver has been designed for use with low voltage electro-optic deflector "Q" Switches but will operate into any suitable capacitive device. Although limited to 20kHz, it will run at 28kHz from 12 volts and could easily be modified to run at much high rates with suitable cooling.
