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.
FEATURES
s Excess noise ratios (ENR): up to 20dB
s Broad bandwidth
s Excellent long term stability
s Life up to 20,000 hours
s AC, DC, or pulsed operation
APPLICATIONS
s Noise figure measurement
