Description

Information from: "The Story for Electronics Development at the General Electric Company", pages 44 & 48 by W. C. White. Also from "Fact Sheet AWA Tube Collector Group" vol 6, no 1, 1981:" In the late 1920's the General Electric Co introduced one of the first magnetrons that had passed from the experimental stage. It was designated FH-11. There are two anodes, semi cylindrical in shape and separated by two equal longitudinal slits. These anodes are supported by two leads whih run out of the top of the tube and serve as external connections. Fins on each one provide additional dissipation of heat. Technical information: Filament 5 volts at 5amps, Anode voltage 1500 at .050 amps. Field strength 700 Gausses. Output as approximately 15 watts with minimum operable wavelength of 0.75 meters. At 50.0 meters an output of 50 watts could be obtained. A General Electric catalog dated May, 1930 gives additional data on the FH-11".
