2J55
X-Band Magnetron
2J55 is a fixed frequency pulsed type X-band magnetron, designed to
operate in the frequency range of 9345 to 9405 MHz with a peak output
power of 50 kW. It is packaged and waveguide output type and forced
air cooled.

Note 1: Measured with heater voltage of 6.3V and no anode input power,
the heater current 1imits 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:
