Microwave Noise Tubes & Noise Sources
Description
Ordering Information
High Energy Devices’ 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 PS237 through PS240 current-regulated power
supplies can be used to operate many of the noise
sources described herein.
A complete part number is represented by the
information in the Part Number column of the
specification table.
