Lessons Learned - Voyager - S/X-Band Antenna Subsystem Intermodulation Products at Cold Temperatures (~1976)
Year: 1996
Abstract: Abstract:
Qualification testing at extreme cold temperatures found that noise could be generated from the minute differential expansion between semi-rigid aluminum coaxial cables and their attached stainless steel shells. Beware of the intermodulation product phenomenon, and test for it during antenna subsystem pre- and post-environmental tests, after antenna installation on the spacecraft, and prelaunch.
