Applied Systems Engineering—Microwaves With Fine Fidelity (RF)

[SatNews] Applied Systems Engineering has introduced their Model 337C Magentron Transmitter.

The Model 337 Power MOSFET Modulator, Magnetron Transmitter is designed to operate magnetrons up to 500 kW. The continuously variable pulse width range is 0.15 to 2.0 microseconds, or greater, at PRF up to 5 kHz.  Maximum pulse width is determined by the pulse storage capacitor value and 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.  Both HVPS and modulator contain modular plug-in subassemblies. A higher power version of the Model 337 (designated Model 527) is available for operation of magnetrons up to 1MW.
