MAF1421B X-Band Magnetron MAF1421B 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 ---Peak anode current Average anode power input Duty cycle Pulse duration Rate of rise of voltage pulse Anode temperature V.S.W.R at the output coupler Min 2.0 0.05 - Max 4.0 13 0.001 1.0 70 100 1.5:1 Unit A W µs kV/µs °C - Min 5.7 60 3.4 3.6 9380 Typical 6.3 3.6 4.0 9410 Max 6.9 3.8 9440 ---- ELECTRICAL ---Heater voltage Heater current (Note 1) Preheat time Peak anode voltage (Note 2) Peak output power (Note 2) Frequency (Note 2) Unit V A S kV kW MHz 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.
