Technical Information Rev.6 MAF1615B X-Band Magnetron MAF1615B is designed for the magnetron of x-band radar system. The frequency range is fixed <9380 - 9440MHz> and the peak output power is 12kW. ---- MAXIMUM RATINGS ---Min Max Unit Peak anode current (Note3) 4.6 6.8 A Average anode power input - 40 W Duty cycle - 0.001 - Pulse duration 0.07 1.25 us Rate of rise of voltage pulse - 80 kV/us Anode temperature - 120 degree centigrade V.S.W.R at the output coupler - 1.5:1 Min Typical - ---- ELECTRICAL ---Max Unit Heater voltage at stand by and short pulse 7.5 8.0 8.5 V at long pulse 6.0 6.3 6.6 V - - - A 65 - - S Peak anode voltage (Note 2) 5.4 5.8 6.0 kV Peak output power (Note 2) 12.0 12.5 - kW 9440 MHz Heater current (Note 1) Preheat time Frequency (Note 2) 9380 9410 Notes: 1. Measured with heater voltage of 8.0V the heater current limits are 0.62A minimum, 0.68A maximum and with heater voltage 6.3V the heater current limits are 0.52A minimum, 0.58A maximum. Reduction of heater voltage at operating is required. 2. Measured at peak anode current 5.8 A. 1-1,Fukuoka 2-chome, Fujimino-city Saitama-prefecture. 356-8510 Japan Phone:049-278-1298 Fax :049-278-1419 Technical Information Rev.6 3. Any overshoot of the anode current is not acceptable. The impedance of this magnetron is the same as current magnetron excluding the transient impedance. This means that the additional reactance should be required for adjustment the anode current wave form, if this magnetron will be installed into the similar modulator circuit as before. 1-1,Fukuoka 2-chome, Fujimino-city Saitama-prefecture. 356-8510 Japan Phone:049-278-1298 Fax :049-278-1419
