MICROWAVE NOISE TUBES & NOISE SOURCES

TD/TN Series

DESCRIPTION

CP Clare’s TD Series of gas discharge microwave noise tubes and TN Series of gas discharge microwave noise

sources are the element in a microwave RF system that allows accurate measurements of the noise figure of the

receiver or its components. The requirements of a device used for making such noise figure measurements

include broad bandwidth inherent in the active element, stability, ease of operation, and long life. In general, the

range of usefulness of these noise sources permits measurements of noise figures from about 2 to 30dB. The

PS-237 through PS-240 current-regulated power supplies can be used to operate many of the noise sources

described herein.
