A Metal Triode for Ultra-High-Frequency Operation

The metal tube here described (designated type DCM-1) is established as a practical design, suitable for production. It can be used as a converter in the wavelength range of 25 to 30 centimeters, and as an oscillator with a power output of 1 to 5 watts in the wavelength range of 30 to 60 centimeters. It can also be employed as an amplifier with an amplification coefficient K of 3 to 4 at a wavelength of 25 centimeters, or with a K of 6 to 7 at λ of 40 centimeters. If used as a regenerative amplifier, a K of 10 can be secured at λ of 25 centimeters, and a K of 15 at λ of 40 centimeters.
