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
