9M31 X-Band Magnetron 9M31 is a fixed frequency pulsed type X-band magnetron, designed to operate in the frequency range of 9.38 to 9.44GHz with a peak output power of 50kW. It is packaged and waveguide output type and forced air cooled. ---- MAXIMUM RATINGS ---Peak anode current Peak anode power input Duty cycle Pulse duration Rate of rise of voltage pulse Anode temperature V.S.W.R. at the output coupler Min 3.5 - Max 16.0 230 0.001 2.5 100 100 Unit A kW us kV/us - 1.5:1 - Max 6.9 13.0 9.44 Unit V S kV kW GHz degree centigrade ---- ELECTRICAL ---Min 5.7 120 11.0 40 9.38 Typical Heater voltage (Note 1) 6.3 Preheat time Peak anode voltage (Note 2) 12.0 Peak output power (Note 2) Frequency (Note2) Note: 1. Measured with heater voltage of 6.3V and no anode input power, the heater current limits are 0.9A minimum, 1.1A maximum. For average pulse input powers less than 150 watts, the heater voltage must be reduced within 3 seconds after the application of h. t. according to the following schedule: Pi Volts 150 (Pi=mean input power in watts.) Ef = 6.3 1 − 2. Measured at peak anode current 12.0A. For further information on the use of the magnetron, Please contact New JRC.
