A HYBRID SOLID STATE MARX MAGNETRON MODULATOR

A Solid State Marx combined with a standard pulse transformer results in a low cost and flexible modulator for magnetron application. The unique features of the Solid State Marx of variable pulse width, fast adjustable rise times, changeable amplitude and high reputation rate makes it ideally suitable for a dynamically flexibility modulator. The Magnetron and its pulse transformers can be operated at considerable distances from the modulator and power source by using a matching cable, which results in significant installation flexibility. The unique properties of the Solid State Marx enable the core bias and heater supply to be located at the modulator without additional interconnecting wiring to the magnetron. The result is a simplified cable plant and operation. The paper will delineate this unique design of the Solid State hybrid modulator and its performance.
