Gore provides high-performance cable assemblies with significant mechanical and electrical advantages for high-flex applications in aerospace and defense, spaceflight, semiconductor, and test and measurement environments. Our selection of GORE Microwave/RF Assemblies offers the following benefits over competitors such as:

  • precise and repeatable measurements in wide-ranging frequencies
  • proven consistent phase and amplitude stability
  • low insertion loss cables with reliable VSWR
  • cable assemblies with best EMI/EMC performance
  • cable assemblies with lowest Error Vector Magnitude (EVM)
  • durable RF cables that withstand shock, vibration, abrasion, chemicals and more
  • temperature-stable cable assemblies for extreme thermal environments
  • faster, easier routing with tight bending coaxial cable
  • improved installation with ultra-flexible coaxial cable
  • weight savings with a variety of lightweight, high-flex coax cable diameters
  • design freedom with a variety of coaxial microwave connectors

We balance ruggedness, low weight and flexibility with precise and repeatable measurements in one solution. Our cable assemblies with best RF shielding effectiveness and cable assemblies with lowest RF leakage are unmatched by alternatives available today in many industries.

Durability & Flexibility by Design

We engineer our ruggedized cable assemblies from the inner conductor out. Beginning with the inherent high-flex properties of our coaxial cable material — expanded polytetrafluoroethylene (ePTFE) — we select cable jacket and dielectric coax insulation layers using an extensive characterization database.

Our specialized coaxial cable construction methods and connectors ensure consistent electrical performance during flexure. We integrate these methods and materials to reproduce and deliver reliable RF microwave cables.

Our flexible RF cables have little resistance to bending and very low spring back because the helically wrapped shielding increases in length outside the bend and decreases on the inside. During bending and flexure, the shielding doesn’t open or allow electromagnetic interference (EMI) leakage — unless the recommended minimum bend radius is exceeded substantially.

In some of our cable designs, stranded center microwave coaxial wires and unique materials further enhance their flexibility and low spring back. Products like GORE® Microwave/RF Assemblies for general purpose test and interconnect are proven much easier to route in complex system configurations than competitors.

Besides their elasticity, our selection of microwave coaxial cables also includes layers of rugged protection, so they can easily handle demanding conditions, like abrasion, shock, vibration and chemicals. Many of our assembly types are proven to withstand extreme heat and humidity for a prolonged lifespan.

For instance, GORE-FLIGHT® Microwave Assemblies offer a fit-and-forget solution for civil and defense aircraft applications. These electrical-stable cable assemblies are proven to deliver the lowest insertion loss and more reliable VSWR after installation, during use and over time.

Rigorously Tested & Pre-Qualified

Gore understands failure modes and mechanisms associated with RF cable performance degradation. So we rigorously test our products before routing, after installation and in real-world conditions according to the most current industry standards, including but not limited to:

  • cable flex test standards and Gore internal simulators to establish and document an expected assembly flex life
  • coaxial cable testing procedure as one of many to certify an assembly’s electrical and mechanical performance, for instance, shock and vibration
  • RF leakage test to validate an assembly’s RF shielding effectiveness

We make sure all of our products meet, and in some cases exceed, industry standards and our customers’ requirements, like RoHS-compliant cable assemblies. We can save you time and money with pre-qualified designs for many applications of coaxial cables across industries.

Proven Reliable Solutions


Gore offers a wide selection of coaxial microwave cables in a variety of configurations and diameters to meet your specific application requirements for aerospace and defense, spaceflight, semiconductor or test and measurement. We can also provide coaxial cable phase matching and time delay upon request.

While our products differ in appearance depending on their level of durability and flexibility, our standard coaxial cable types retain their low- or ultra-low insertion loss and VSWR performance regardless of the application and conditions.

For example, GORE® PHASEFLEX® Microwave/RF Test Assemblies are an ideal choice for testing critical spaceflight systems operating in high thermal environments. This version ensures accurate and repeatable coaxial cable performance with predictability.

Suppose our standard versions don’t meet your criteria. In that case, we can customize a more flexible microwave cable to accommodate your desired application or even a high-temperature coaxial cable.

Since the connector choice determines a specific cable assembly’s shielding effectiveness, we offer various types of microwave coaxial connectors designed specifically for our assemblies. We engineer each connector to complement the performance of each assembly, minimizing loss and reflection for optimized signal transmission. Most microwave coaxial connectors for our standard versions can also be used with our high-flex life cable assembly.
