Phase-Stable RF Performance from DC to 70 GHz
Precision RF Cable Assemblies for Bench-Top and Field Use
Gore's General Purpose Microwave/RF Assemblies combine low insertion loss, excellent VSWR, and repeatable phase stability across temperature — meeting the exacting demands of modern test, measurement, and system integration work.

Phase-stable RF cable assemblies for bench-top and field use. Covering DC to 70 GHz with low insertion loss, low VSWR, and stable phase across temperature. Available with a broad selection of connector interfaces and cable diameters to match any system integration requirement.
Why Choose Gore General Purpose Microwave/RF Assemblies?
Reliable Phase Stability Across Temperature
Phase drift under thermal cycling is the primary source of measurement error in RF test setups. Gore's ePTFE dielectric and precision cable construction minimize phase variation across temperature, ensuring your calibration stays valid from cold start through full operating temperature.
Low Insertion Loss to 70 GHz
As frequencies climb, cable loss becomes the dominant system budget constraint. Gore General Purpose assemblies are engineered for minimum attenuation per unit length, extending measurement range and preserving signal integrity in both benchtop analyzers and field-deployed systems.
Broad Connector Compatibility
System integrators rarely work with a single connector standard. These assemblies are available with SMA, 2.92 mm (K), 2.4 mm, N-type, TNC, and custom interfaces, enabling one qualified cable family to serve across multiple instruments and frequency bands.

Frequently Asked Questions
What is the maximum usable frequency of these assemblies?
Gore General Purpose RF Assemblies are specified up to 70 GHz, covering Ka-band and beyond. Connector choice is the primary frequency limiter: SMA connectors are typically used to 18 GHz, 2.92 mm (K) to 40 GHz, and 2.4 mm to 50–65 GHz.
How does phase stability compare between these and standard RG cables?
Standard RG-type cables use solid or foam polyethylene dielectric that exhibits significant phase change with temperature. Gore's ePTFE dielectric has a much lower coefficient of thermal expansion, resulting in phase variation typically 5–10× smaller than conventional cables over the same temperature range.
Can RSTECH source custom assembly lengths and connector configurations?
Yes. RSTECH Electronics works with Gore to supply custom lengths, connector types, and termination styles. Lead time and minimum order quantities depend on configuration — contact us with your specific requirements.
Are these assemblies suitable for field use or only laboratory environments?
While optimized for benchtop performance, these assemblies use durable PTFE/FEP jacketing and robust connector interfaces that withstand field conditions. For the most extreme environmental requirements, Gore also offers ruggedized airframe and PHASEFLEX series assemblies.
