Semi-Rigid RF Cables for High-Performance RF and Microwave Applications

INERGEK provides professional semi-rigid RF cable solutions for customers who require stable electrical performance, precise mechanical dimensions and reliable cable assembly support. Our semi-rigid cable products are available in standard and low-loss configurations, making them suitable for RF, microwave, communication, test equipment and industrial interconnect applications.

Semi-rigid coaxial cables are widely used where consistent impedance, low signal loss, stable shielding and controlled cable forming are required. Compared with flexible cable structures, semi-rigid cables provide excellent dimensional stability and are ideal for compact RF layouts, high-frequency modules, precision test systems and customized cable routing.

Standard and Low-Loss Semi-Rigid Cable Options

INERGEK offers both standard semi-rigid cable and low-loss semi-rigid cable options. Customers can select cable structures according to frequency range, insertion loss requirements, forming requirements, impedance, outer diameter and connector interface.

Our semi-rigid RF cable solutions are suitable for:

• RF and microwave interconnects
• Communication equipment
• Test and measurement systems
• Antenna systems
• RF modules and microwave components
• Industrial RF equipment
• Custom cable assembly projects
• Prototype and production-level RF designs

Material Options for Different RF Requirements

To support different performance and cost requirements, INERGEK offers multiple outer conductor and dielectric material options.

Outer Conductor Options

Available outer conductor options include:

• Copper outer conductor
• Tri-metal alloy cable options
• Tin-plated cable options
• Aluminum outer conductor options

Copper semi-rigid cables are commonly selected for strong conductivity and stable RF performance. Aluminum and plated options can be considered when weight, surface finish, corrosion resistance or project-specific requirements are important.

Dielectric Options

INERGEK supports multiple dielectric materials, including:

• LDPTFE
• PTFE
• FEP

Different dielectric materials can be selected according to electrical performance, temperature resistance, flexibility of processing and final application environment.

Multiple Impedance Options

INERGEK can support a wide range of impedance requirements for custom RF cable designs.

Available impedance options include:

• 10 ohm
• 15 ohm
• 25 ohm
• 50 ohm
• 75 ohm

50 ohm semi-rigid cables are commonly used in RF and microwave systems, while other impedance values can be selected for special matching, testing, power transmission or customized design requirements.

Wide Range of Semi-Rigid Cable Sizes

INERGEK supplies semi-rigid RF cables in multiple outer diameter sizes to meet different design and assembly needs.

Available OD sizes include:

• .034"
• .043"
• .047"
• .070"
• .085"
• .090"
• .118"
• .125"
• .130"
• .141"
• .250"

These size options allow engineers to select the right balance between mechanical strength, bend radius, RF performance, power handling and installation space.

Precision Dielectric Extrusion and Copper Tube Processing

INERGEK is equipped with professional dielectric extrusion process capability and copper tube processing capability. These processes are essential for producing stable semi-rigid RF cables with consistent dimensions and reliable electrical performance.

Our production capabilities include:

• Dielectric extrusion process control
• Copper tube processing
• Precision cutting
• Cable forming support
• Cable end preparation
• Accurate stripping process
• Connector termination support
• Custom cable assembly manufacturing

For semi-rigid RF cables, stripping and end preparation are especially important. Clean conductor exposure, controlled dielectric removal and stable outer conductor geometry help ensure reliable connector termination and consistent RF performance.

Custom Semi-Rigid RF Cable Assemblies

In addition to bulk semi-rigid cable supply, INERGEK also supports custom semi-rigid RF cable assembly production.

We can help customers with:

• Custom cable length
• Cable forming and bending
• Connector termination
• Prototype samples
• Small-batch production
• Bulk production
• Custom packaging
• RF cable assembly solutions based on customer drawings or requirements

Whether customers need straight cable assemblies, formed cable assemblies, low-loss solutions or special impedance designs, INERGEK can provide flexible support for different project stages.
