Flexible RF Cable Assemblies​

Flexible RF Cable Assemblies

Flexible RF cable assemblies strike an ideal balance between the electrical performance of semi-rigid cables and the installation flexibility of traditional flexible coaxial cables.

These assemblies feature a solid silver-plated copper conductor, offering excellent conductivity and minimal signal loss. A dual-layer shielding structure—combining a precision-wrapped metal tape shield with an outer braided shield—effectively minimizes signal leakage and provides robust resistance to external electromagnetic interference. A solid PTFE dielectric ensures stable electrical characteristics, while an FEP jacket provides superior protection in demanding operating environments.

Combining the RF performance of semi-rigid cables with the handling convenience of flexible cables, these assemblies offer stable phase characteristics, shielding effectiveness exceeding 90 dB, low VSWR, and reliable high-frequency transmission. Their lightweight, flexible design simplifies routing and installation, making them particularly well-suited for space-constrained applications.

Compatible with standard semi-rigid connectors, these assemblies serve as an ideal alternative to traditional semi-rigid cables, especially in sectors demanding high flexibility, durability, and installation efficiency—such as RF test and measurement systems, aerospace equipment, communication systems, and high-frequency electronic applications.

Why Choose Our Flexible RF Cable Assemblies

• Silver-plated copper inner conductor delivers strong conductivity and stable, low-resistance signal transmission.
• Double-layer shielding — wound metal tape plus braid — pushes shielding effectiveness above 90dB.
• Solid PTFE dielectric and rugged FEP jacket protect signal integrity in harsh environments.
• Performs like semi-rigid cable but bends by hand, no special tools or fixtures needed.
• Stable phase performance holds steady across repeated flex cycles and temperature swings.
• Wide temperature range from -55°C to +200°C suits extreme outdoor and industrial conditions.
• Lightweight, flexible construction simplifies routing and installation in tight, space-constrained enclosures.
• True semi-rigid replacement — mates directly with standard semi-rigid connectors for easy swaps.

Applications of Flexible RF Cable Assemblies

Precision Test & Measurement

Bench test setups, VNA test cables, and calibration kits all depend on repeatable phase performance. These assemblies hold up through thousands of flex cycles without drifting.

Aerospace & Defense

Lightweight construction and a wide temperature range make these cables a good fit for avionics harnesses, phased-array antennas, and radar systems, where every gram and every degree of thermal swing counts.

Telecommunications & 5G Infrastructure

Base stations, small cells, and distributed antenna systems (DAS) often need cable that routes through tight enclosures. Flexible RF cable assemblies simplify that installation without sacrificing shielding.

Satellite & Microwave Systems

RF front-end interconnects, up/down converters, and SATCOM ground equipment benefit from the combination of low loss, strong shielding, and flexible routing.

Medical & Scientific Instrumentation

Imaging systems and lab equipment need consistent electrical behavior over time. Stable phase and low VSWR support accurate, repeatable readings.

Industrial & Automation Systems

In environments with vibration or repeated movement, these cables outlast rigid alternatives while keeping signal integrity intact.

Customization

Every application has its own constraints, so we build these assemblies around your specs, not the other way around.

• Length & diameter — from short jumper cables to longer interconnects, sized to your layout.
• Connector options — SMA, N-Type, TNC, 2.92mm, 3.5mm, and other semi-rigid style interfaces, in straight or right-angle, male or female configurations.
• Phase-matched pairs and sets — matched cable assemblies for applications where signal timing between channels has to line up.
• Jacket color and labeling — including OEM branding and private labeling for resale or system integration.
• Extra ruggedization — additional shielding or armor layers for harsh mechanical or EMI environments.
• Test data on request — VSWR, insertion loss, and phase test reports for each batch, so you know what you’re getting before it ships.

We also support small-batch sampling before you commit to a full production run — useful if you’re validating a new design or qualifying a new supplier.

FAQ

1.What’s the difference between flexible RF cable assemblies and semi-rigid cable?

Semi-rigid cable holds its shape once bent and needs special tools to route. Flexible RF cable assemblies deliver similar electrical performance but bend by hand and can be re-routed as needed, which makes installation and design changes much easier.

2. Can these cables replace semi-rigid cable directly in an existing design?

In most cases, yes. Since these assemblies mate with standard semi-rigid connectors, you can usually swap them in without redesigning your interface. For critical applications, we recommend confirming compatibility with our engineering team first.

3. How much shielding do these cables provide?

Shielding effectiveness exceeds 90dB, thanks to the double-layer outer conductor — a precision-wound metal tape under a tight braided shield.

4. What temperature range can these cables handle?

They’re rated from -55°C to +200°C, so they hold up in both cold outdoor installs and high-heat environments like engine bays or industrial enclosures.

5. Are phase-matched cable pairs available?

Yes. We offer phase-matched sets for applications like phased-array antennas or multi-channel test setups, where signal timing across channels needs to stay aligned.
