Precision RF Signal Transmission for Extreme Environments
Coaxial Cables That Hold Impedance When Every dB Counts
Gore Coaxial Cables maintain stable electrical characteristics across wide temperature ranges, pressure changes, and mechanical stress. Specified wherever signal fidelity cannot be compromised.
High-performance coaxial cables with stable electrical characteristics over wide temperature ranges, ideal for signal transmission in demanding environments.
Why Choose Gore Coaxial Cables?
Phase Stability Under Stress
In phased-array radar, beamforming systems, and precision test setups, even small phase deviations corrupt measurements and degrade antenna performance. Gore coaxial cables are engineered for minimal phase change under flex, temperature swing, and mechanical load — keeping your system accurate.
Low Loss at High Frequencies
Conventional coax suffers increasing dielectric loss as frequency rises. Gore's ePTFE insulation provides an exceptionally low dielectric constant and loss tangent, preserving signal amplitude at microwave and millimeter-wave frequencies where ordinary cables become inefficient attenuators.
Durability That Outlasts the Mission
Aerospace and defense platforms demand cables that survive the full program lifecycle — often 20+ years of deployment, maintenance cycles, and thermal extremes. Gore coaxial cables are proven in airborne, shipboard, and ground-based systems where replacement is expensive or impossible.

Frequently Asked Questions
What frequency range do Gore coaxial cables support?
Gore offers coaxial cables operating from DC to 67 GHz depending on the specific product line. The ePTFE dielectric enables low loss across this range, making them suitable for microwave and millimeter-wave applications.
Are these cables suitable for phase-matched pairs or arrays?
Yes. Gore can supply phase-matched cable assemblies for applications like phased-array antennas, interferometry, and balanced measurement systems where electrical length matching between multiple paths is critical.
How do Gore coaxial cables perform under repeated flexing?
Gore cables are specifically engineered for flex life. The ePTFE dielectric maintains its structure under repeated bending, and the conductor and shielding systems are optimized to prevent impedance drift that occurs in standard coax after flexing.
Can RSTECH supply these with specific connector terminations?
