RF COAXIAL CABLE - VALIDATED RELABILITY

Teledyne Storm Microwave delivers high frequency single-cable alternatives compliant with stringent environmental, mechanical, and RF performance requirements. For over 35 years, Teledyne Storm cables have been the design-in choice of program design engineers for many mission critical applications.

Our cables are selected for attributes that include phase stability with temperature change, mechanical robustness when exposed to extreme environmental conditions, extended flex-life, and low attenuation for a given cable diameter to be installed in constricted space.

TSM cable can be offered in a number of constructions related to jacket materials, center conductor, dielectric core, outer conductor, and protective braid, as well as in a range of outer diameters based on your desired RF performance compliance requirements. Phase matching of assemblies is available on request.

All of these parameters are consideration points in optimizing your cable selection to ensure system performance compliance. Our Harness Engineering Team is available to work with you early in the process to review your system goals and offer support in deciding on the RF interconnects best suited to ensure your milestones are met, and met reliably.

CONNECTORS Click table to view PDF

The 38999 style connector is one of the most common connectors used with harness assemblies, due to their high density and quick connect features.

These connectors not only deliver a quick disconnect capability, they offer a keying feature that prevents mismating.

Accurate mating alignment of the 38999 connector is critical, because it controls RF performance parameters such as insertion loss, return loss, and shielding effectiveness of the cables terminated with the connector.

Connector contacts are typically stainless steel and gold-plated beryllium copper, with a PTFE-based dielectric material.

Teledyne Storm has special contacts available which allow our harness assemblies to operate at frequencies much higher than the typical MIL Standard contacts allow.

Finally, the core of the connector is located within a supportive shell that is most commonly made from aluminum that is anodized or plated for corrosion protection.

Teledyne Storm has broad experience supplying Tailored Harness Solutions incorporating the 38999 style connector. This expertise in materials selection, alignment control, and the overall cable termination process ensures that our harnesses will be achieve your RF and mechanical performance requirements.

TSM delivers high frequency single-cable alternatives compliant with stringent mechanical and RF performance requirements.

The technology built into our Harness Solutions is based on over 35 years of coaxial cable design and manufacturing expertise.

TSM cables address flexibility, shielding, attenuation, shock and vibration requirements with a comprehensive range of constructions that deliver the highest levels of reliability for today’s—and tomorrow’s—applications.

The TSM cables used in building our harnesses include Storm Flex®, Phase Master®, True Blue®, and dB Miser™ addressing flexibility, phase stability, durability, and low loss requirements.
