Proven performance and reliability for 32 GHz spaceflight applications
Failure isn’t an option in space, nor is it an option for cables used in space. These cables must endure take-off and harsh landings, stay reliable in use throughout the mission, and never require maintenance. After all, there’s no quick fix millions of miles from home.
Gore’s High-Frequency Cable Assemblies for Ka Band Frequencies (Type 5G Series of GORE® Spaceflight Microwave/RF Assemblies) are qualified for spaceflight applications in three separate phases — integration, launch, and in-orbit — to ensure consistently reliable performance for the duration of the mission.
Unlike the standard bifurcated contact used in test connectors, the robust connectors of the Type 5G Series withstand the vibration of launch and orbit without compromising signal performance. In addition, the low profile of these connectors increases flexibility during the layout process of satellite design.
With superior radio frequency performance at 32 GHz, the cables are optimized for Ka band uplink and downlink applications.

Reliable performance of microwave/RF cable assemblies with longer service life and reduced equipment downtime results in lower costs for testing in laboratory, production, and field test environments. A new white paper from W. L. Gore & Associates evaluates the durability and performance over time of several 18-GHz microwave/RF cable assemblies described as having a ruggedized construction with similar specifications.
W. L. Gore & Associates (Gore) has continuously expanded the company's microwave/RF solutions at higher frequencies by designing cable assemblies that are reliable and will perform over time, and Gore is now addressing industry requirements for enhanced performance in the 60-70 GHz range. At the 60-70 GHz range, there is increased need to maintain measurement accuracy, especially in Network Analyzers, Oscilloscopes, Analog Signal Generators, Communication Testing, Chamber Testing, and mm-Wave to name a few key applications.
