GORE® PHASEFLEX® Microwave / RF Test Assemblies

Coaxial & Microwave / RF Cable Assemblies

Includes typical applications, features and benefits, construction, specifications, and part number information.

English (U.S.)


In today’s competitive electronics industries, reliability is essential for applications that use microwave/RF cable assemblies to ensure consistent, repeatable measurements and to maintain electrical performance over time. So, cable assemblies must be durable enough to withstand continuous movement, flexing, and exposure to environmental conditions while maintaining reliable electrical performance. But, a recent study showed that globally more than 75% of microwave/RF cable assemblies are replaced frequently due to damage during installation or operation.

Durable, Reliable Performance Now and Over Time

GORE PHASEFLEX Microwave/RF Test Assemblies are the only internally ruggedized, flexible RF test assembly that provides consistent electrical performance with long service life in demanding environments. Our assemblies have a durable construction that resists not only crushing, but also kinking and twisting to prevent damage that could be caused by exceeding a cable’s minimum bend radius. Our assemblies also maintain precise, repeatable measurements, while withstanding frequent connecting and disconnecting, and they perform reliably even after extensive flexing with some cable constructions exceeding 100,000 flex cycles.

So, can you justify replacing your microwave/RF assemblies several times a year? Or, would you rather use one assembly for the life of your test equipment? GORE PHASEFLEX Microwave/RF Test Assemblies are more reliable and last longer than typical cable assemblies used in the industry — years rather than months.
