Model 327 Magnetron Transmitter
Available from Applied Systems Engineering, Inc.
The Model 327 Power MOSFET Modulator, Magnetron Transmitter is designed to operate magnetrons up to 150kW. The continuously variable pulse width range is 0.15 to 2.0 microseconds, or greater, at PRF up to 5kHz. Maximum pulse width is determined by the pulse storage capacitor value and the magnetron capability. The Model 327 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 327 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 327 (designated Model 337) is available for operation of magnetrons up to 250kW. Output Power up to 150kW. Duty Cycle 0.001. Pulse Width Range 0.15 to 2.0 us. PRF Range 0 to 5kHz. RF Rise Time 100 ns, nominal. RF Fall Time 150 ns, Nominal. RF Pulse Droop 0.5dB, Max. Delay input to RF 10us, Max. Operating Temperature 0 to 50 degrees. 19.25 x 19 x 26 inches. Cooling - Internal Forced Air.
