Abstract
Provided is a modulator having two amplifying stages for supplying high-voltage pulses to the primary winding of a transformer connected to a microwave transmitter tube. The first stage uses field-effect transistors connected in a common source configuration to amplify input pulses to drive the second stage, which uses field-effect transistors connected in a common gate configuration to drive the transformer. The circuit configuration provides a large voltage swing across the transformer primary and a short transistor switching time.
