Depending on the chosen GaN field effect transistor (GaNFET) and driver, these GaN pulsers are capable of generating pulses ranging from 100 - 650 V and 5 - 60 A in 0.25 - 8 ns using simple designs with easy control, few-nanosecond propagation delays, and MHz repetition rates. We experimentally demonstrate a simple 250 ps, 100 V pulser measured by a directly coupled 2 GHz oscilloscope.
