Technical Information Rev.1 MAF1422B X-Band Magnetron MAF1422B is designed for the magnetron of x-band radar system. The frequency range is fixed <9380 - 9440MHz> and the peak output power is 6kW. ---- MAXIMUM RATINGS ---Min Max Unit 2.5 6.0 A Average anode power input - 25 W Duty cycle - 0.001 - Peak anode current Pulse duration 0.05 1.25 us Rate of rise of voltage pulse - 100 kV/us Anode temperature - 100 degree centigrade V.S.W.R at the output coupler - 1.5:1 - ---- ELECTRICAL ---- Heater voltage Heater current (Note 1) Min Typical Max Unit 6.0 6.3 6.6 V - - - A 60 - - S Peak anode voltage (Note 2) 4.4 4.5 4.8 kV Peak output power (Note 2) 6.0 6.5 - kW 9380 9410 9440 MHz Preheat time Frequency (Note 2) Notes: 1. Measured with heater voltage of 6.3V and no anode input power, the heater current limits are 0.5A minimum, 0.6A maximum. No reduction of heater voltage at operating is required. 2. Measured at peak anode current 4.5 A. 3. Any overshoot of the anode current is not acceptable. And, sagging waveform of the anode current causes the poor spectrum and the shifting frequency in the pulse since a magnetron current pushing characteristics. 1-1,Fukuoka 2-chome, Fujimino-city Saitama-prefecture. 356-8510 Japan Phone:049-278-1298 Fax :049-278-1419 Technical Information Rev.1 1-1,Fukuoka 2-chome, Fujimino-city Saitama-prefecture. 356-8510 Japan Phone:049-278-1298 Fax :049-278-1419
