Temperature Cycling Traveling Wave Tubes

Posted by Tom Ryan on Mar 15, 2015 1:52:00 PM

inTEST Thermal Solutions (iTS) has designed a multi-zone thermal plate for hot/cold temperature cycling of microwave signal amplifiers used in satellite data communications. The heart of the amplifier is a travelling wave tube (TWT) and power supply. In their space-borne environment, TWTs are exposed to extreme temperatures that influence the strength and stability of their magnetic field and can adversely affect their RF signal output. Rigorous thermal stressing of TWTs is required to characterize RF signal outputs and ensure trouble-free operation after deployment.
