Filament Vf 6.3 Volts / If 2.8 Ampere / Half indirect
Description

First operative X-band pulsed magnetron. Samples were delivered in autumn 1941 by BTH and GEC, the full production being planned for 1942. CV108 had 12 resonating slots, cut by gear cutting machines, the anode bore of 10.5 mm and cathode diameter of 5.75mm. 12 cavities helped to keep the magnetic field at a value, 2670 Oe, still obtainable using a permanent magnets small enough to be used in airborne radar equipment.

Typical operating conditions:

  • 11.5 kV at 12.5 A input pulses
  • 17 kW peak output pulses at 9375MHz
  • forced-air cooling required.

Production continued until April 1944, when it was replaced by CV208 and CV209.
