The 884 Gas Tube as a Noise Source

Abstract

This noise source was developed for use in the modulator of a radar jammer. The circuit is built around two 884's and a 6L6. It produces noise with a bandwidth of about 4 Mc. The peak-to-peak output is in the vicinity of 35 volts but varies as much as 20 percent with tubes, The oscillations which most 884 noise sources exhibit are attenuated by drawing considerable current through the gas tubes. The bandwidth is obtained by feeding back some of the noise output to the input.
