Model 337

250 kW Magnetron Transmitter

Magnetron Transmitter

The Model 337 Power MOSFET Modulator, Magnetron Transmitter is designed to operate magnetrons up to 250 kW. The RF pulse is continuously variable, and the pulse width is determined by the magnetron capability. The Model 337 Modulator is not damaged by magnetron arcs. Arc energy to the magnetron is limited which actually helps to clean-up an arcing magnetron. The Model 337 Modulator is a proven, reliable design which fills a need for an inexpensive, versatile transmitter with excellent RF output fidelity. The modulator HVPS is a very efficient, duty cycle regulated DC to DC converter design. A higher power version of the Model 337 (designated Model 527) is available for operation of magnetrons up to 1MW.
