Technical Information Rev.5 MAF1611B X-Band Magnetron MAF1611B is designed for the magnetron of x-band radar system. The frequency range is fixed <9380 - 9440MHz> and the peak output power is 4kW. ---- MAXIMUM RATINGS ---Min Max Unit Peak anode current (Note3) 2.0 4.0 A Average anode power input - 16 W Duty cycle - 0.001 - Pulse duration 0.05 1.25 Rate of rise of voltage pulse - 50 Anode temperature - 100 us kV/us degree centigrade V.S.W.R at the output coupler - 1.5:1 - ---- ELECTRICAL ---- Heater voltage Heater current (Note 1) Preheat time Min Typical Max Unit 5.7 6.3 6.9 V - - - A 65 - - S Peak anode voltage (Note 2) 3.4 3.6 3.8 kV Peak output power (Note 2) 3.6 4.0 - kW 9380 9410 9440 MHz 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 3.0A. 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 Technical Information Rev.5 1-1,Fukuoka 2-chome, Fujimino-city Saitama-prefecture. 356-8510 Japan Phone:049-278-1298 Fax :049-278-1419
