Abstract
A high-voltage FET pulser for a synthetic aperture radar transmitter includes an FET ON switch and a tail biter switch both on the floating deck and coupled to a pulse driver circuit through a transformer having a quartz glass tube isolating the secondary winding from the core and primary winding. An active shunt regulator circuit is connected to the output of the FET ON switch to provide a flat output pulse free of ringing.
