Description

Fixed-frequency 8-cavity magnetron requiring forced air cooling and external magnet. Coaxial connector, unstrapped rsonators. 706A-C was the first family of 10 cm magnetrons made by Western Electric, directly derived from the British E1189 carried to U.S. by the Tizard mission in August 1940.

  • 11 kV at 12.5 A typical input pulses
  • 25 kW output pulses.

The family included three fixed frequency factory-tuned types, A, B and C, from 3019 to 3100 MHz.

Raytheon and Westinghouse second sourced the family. The unstrapped 706A to C familiy was replaced from the late 1941 by the strapped family 706AY to GY
