Coaxial & Microwave / RF Cable Assemblies Coaxial & Microwave / RF Spaceflight Cables

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.

Overview

Proven performance and reliability for 32 GHz spaceflight applications
High-Frequency Cable Assemblies for Ka Band Frequencies

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.

Features & Benefits

Gore’s High-Frequency Cable Assemblies for Ka Band Frequencies have a durable cable construction engineered to withstand the rigors of space travel, from takeoff to landing and back. The assemblies deliver:

  • reliable signal integrity with excellent insertion loss and return loss
  • outstanding shielding effectiveness
  • increased flexibility in design layout with robust, low-profile connector solutions
  • proven performance from qualification in integration, launch, and in-orbit phases

Additionally, the assemblies are Globally available from manufacturing facilities in the United States and Europe.

If you have any further questions about the benefits of our High-Frequency Cable Assemblies, please contact us.
