RF Commercial Space Assemblies

Cable assemblies for commercial space applications must be able to endure extreme conditions. Subjected to 30 Mrads of radiation and temperatures anywhere between -90°C to 150°C, cable assemblies must withstand these conditions. As the exploration of space increases, availability of cable assemblies fit for commercial space applications becomes an increasing concern.

Times Microwave Systems has a strong heritage of manufacturing cable assemblies for space applications that is now being put to use for commercial space. With 100% visual inspection and baseline electrical performance (IL, VWSR), Times Microwave Systems is well suited to providing cable assemblies for commercial space applications.

Benefits of High Performance Space Cables

Times Microwave Systems has an extensive heritage building cable assemblies for space applications. Our commercial space cable assemblies are designed with low outgassing materials (per ASTM E595) and vented connectors, if applicable. With Class 100,000 cleanroom manufacturing, our cable assemblies are optimized for the lowest attenuation, radiation resistance, ultra stable performance with flexure, and phase stable performance over temperature.

Frequently Asked Questions

How do you to select the correct cable for your application?

When choosing a cable assembly for a commercial space application, it is important to keep these factors in mind:

  • Radiation environment
  • Shielding effectiveness
  • Performance over flexure of the cable
  • Attenuation
  • Phase stability over temperature
  • Dielectric material – PTFE or TF4®
  • Flexibility of the cable


What is the difference between a PTFE and TF4® dielectric?

Both PTFE and TF4® dielectric cables are fit for commercial space applications, but each dielectric has their place depending on the requirements of the specific use case.

PTFE stands for Polytetrafluoroethylene. PTFE has a high melting point along with its excellent dielectric properties, making it ideal for many microwave applications. However, around 19ºC, PTFE exhibits a non-linear change in phase. Known as the “knee,” this change in phase is problematic for applications where phase stability is crucial.

Times Microwave Systems’ proprietary fluorocarbon dielectric, TF4®, addresses the issues presented by PTFE in terms of phase stability over temperature. TF4 eliminates the non-linear phase performance that occurs between 15 to 25ºC. 

What makes InstaBend® cable assemblies unique?

InstaBend® cables can bend not only in the middle of the cable, but also right behind behind the connector. As replacements for small semi-rigid cables, InstaBend allows for flexibility of routing in tight spaces.
