Data Sheet: Type 5G Series Cable Assemblies for Ka band Frequencies

United States

Data Sheet for GORE Spaceflight Microwave/RF Assemblies - Type 5G Series High-Frequency Cable Assemblies for Ka band Frequencies; includes description, features and benefits, typical applications, performanace specifications, and qualification summary.


With superior radio frequency performance at 32 GHz, the Type 5G Series of GORE Spaceflight Microwave/RF Assemblies are optimized for Ka band uplink and downlink applications. These cable assemblies have been 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.
