Abstract:

The paper describes a new type of gas discharge tube which can be inserted horizontally into a circular waveguide to serve as a standard noise source. Operating in the 3-cm waveband with its terminal short-circuited, the discharge tube gives an excellent matching VS-WR 1.10 0.05 to the waveguide system and has a stable noise output of 18 0.5 db. The result of the present investigation is applicable to the development of noise tubes of the waveguide type for the wavelength regions below 8 mm and above 10 cm. Author
