RF and Microwave Cables

Epec Engineered Technologies provides RF and Microwave coaxial cable assembly services that correlate with our connectorized RF product offerings. We specialize in collaborating with customers to design, engineer, and manufacture customized assemblies to their exact specifications. Utilizing only the highest quality materials we’re capable of providing prototype builds as well as higher volume production quantities.

Our manufacturing flexibility and design capabilities allow us to build from an existing cable assembly drawing with part number references or provide a clean slate turn-key design. All coaxial assemblies are manufactured to handle performance criteria that includes insertion loss, VSWR, temperature, voltage, and RF power.

If required, every assembly can be fully tested and documented for electrical and environmental compliance.

What types of RF and microwave cable assemblies does Epec manufacture?

Epec designs and manufactures a wide range of RF and microwave coaxial cable assemblies for applications requiring high-frequency signal transmission. Assemblies can be supplied with various coaxial cable and connector combinations, application-specific lengths, and custom termination configurations. Whether customers have an existing assembly drawing or need a completely new design, Epec can develop a solution that meets exact electrical and mechanical requirements.

Can Epec support custom RF cable assembly designs?

Yes. Epec works with customers throughout the design, engineering, and manufacturing process to create assemblies tailored to specific performance objectives. Projects can begin from customer drawings and part number references or from a clean-sheet design approach. This flexibility allows engineers to optimize cable selection, connector interfaces, routing requirements, and overall assembly performance for their application.

What performance characteristics are considered when designing RF and microwave assemblies?

RF cable assemblies are designed around application-specific electrical requirements such as insertion loss, voltage standing wave ratio (VSWR), temperature range, voltage rating, and RF power handling. These characteristics play a critical role in signal integrity and overall system performance. By matching the cable and connector design to the intended operating environment, assemblies can achieve reliable performance across demanding RF and microwave applications.

What assembly and fabrication capabilities are available?

Epec offers complete processing capabilities including cutting, stripping, and tinning of flexible, formable, and semi-rigid coaxial cables. Assembly services include both crimp and direct-solder connector attachment methods, custom heat-shrink applications, cable marking, and semi-rigid coax forming and layout. Epec also manufactures phase-matched coaxial assemblies for applications where signal timing consistency is critical.

How are RF and microwave cable assemblies tested?

Testing and validation services can include electrical and environmental verification depending on program requirements. Available testing includes ENA network analyzer measurements, high-potential (hipot) testing, pull testing, thermal cycle testing, and shock testing. If required, assemblies can be fully tested and documented to verify compliance with specified electrical and environmental performance criteria before shipment.
