Semi-Rigid & RF Cable Assemblies

Semi-rigid and RF cable assemblies carry high-frequency signals where performance depends on precise construction: correct cable type, clean terminations, accurate lengths and careful forming.

Overview

What this service covers

Semi-rigid and RF cable assemblies carry high-frequency signals where performance depends on precise construction: correct cable type, clean terminations, accurate lengths and careful forming.

Semi-rigid cable uses a solid outer conductor, which means the assembly holds the shape it is formed to — bends are engineered features, not accidents of installation. That makes dimensional accuracy of the formed assembly part of the specification we build to.

Scope areaWhat it includes
Semi-rigid assemblyCutting, forming and terminating semi-rigid cable to your line drawings, with bend radii and lengths held as specified.
Flexible RF assembliesRF builds on flexible cable where routing requires it, terminated with the connector series specified.
Connector preparationClean, controlled preparation and attachment of RF connectors — the single most performance-critical step in an RF assembly.
Dimensional controlLengths and forming per drawing, so the assembly fits its intended installation.
IdentificationLabeling that keeps track of assembly identity through test, installation and service life.
Electrical checksContinuity and agreed verification as specified for the job.
Configurations are confirmed at enquiry. Supported wire types, connector series, board technologies and test methods are confirmed against your specification before we quote — so what is promised is what is built.

Applications

Where semi-rigid & rf cable assemblies are used

Typical applications for this capability — specific project experience for your application is confirmed during enquiry.

Telecom & transmission equipment

RF interconnects inside transmission and network hardware, where consistent assembly quality keeps performance stable across units.

RF test setups

Bench and production RF test interconnects, where repeatable assemblies mean repeatable measurements.

Laboratory instrumentation

Interconnects for lab environments, built to the connector series and cable specifications the instrument chain requires.

Antenna feed lines

Feed assemblies where length accuracy and careful termination matter to the installed system.

Buyer notes

What experience teaches about semi-rigid & rf cable assemblies

What makes RF assembly different

At high frequencies, the assembly is part of the circuit. Termination quality, cable preparation and dimensional accuracy all show up in performance — an assembly that looks fine can still degrade a signal. That is why RF work is built around clean preparation, controlled forming and agreed verification rather than visual inspection alone.

Why drawings matter more in RF

For semi-rigid assemblies especially, the line drawing defines the product: lengths with tolerances, bend radii, forming geometry, connector orientation. A semi-rigid assembly keeps the shape it is formed to, so the drawing must be right — and questions about geometry belong before forming, not after.

Specifying an RF assembly

The enquiry details that matter: frequency range, cable type or part number, connector series and interface type, lengths and tolerances, forming geometry where fixed, quantity, and any electrical test requirements. Phase-sensitive requirements should be stated explicitly, since they change how builds are matched and verified.

Process

How the work proceeds

RF work rewards patience. Cable is cut to the documented length, formed to the drawing's geometry, and connectors prepared and attached with the right technique for the cable and connector combination. Each completed assembly is verified and recorded.

STEP 1

Requirement & documentation review

Your drawings, BOM and specifications are reviewed, and questions are raised early.

STEP 2

Assembly

The job is built to the documentation by trained assemblers, following the agreed work instructions.

STEP 3

Verification & packing

Agreed checks and tests are performed and recorded; the assembly is labelled and packed for delivery.

FAQ

Technical FAQ

What information should an RF enquiry include?

Frequency range of operation, cable type or specification, connector series and interface, lengths (with tolerances), forming geometry if fixed, quantities, and any test requirements. A drawing with this information lets us respond precisely.

Can you form semi-rigid cable to complex shapes?

Semi-rigid assemblies are formed to your drawing's geometry. Share the line drawing and we will confirm what can be built.

Do you provide phase-matched assemblies?

Requirements like phase matching are job-specific — state the requirement in your enquiry and it will be addressed directly.

Which connector series do you support?

Supported connector series and cable types are confirmed during enquiry, against your specification.

What bend radii can semi-rigid cable take?

Semi-rigid cable is formed to the geometry your drawing specifies, within the cable manufacturer's bend-radius limits for the cable type. Share the line drawing and cable specification and forming feasibility will be confirmed directly.

Can assemblies be supplied with test data?

Agreed verification and its records are defined per job. If your process needs test data with deliveries, state it in the enquiry and it will be included in the quote scope.

How should RF assemblies be stored and handled before installation?

With care for the formed geometry and the connector interfaces: no sharp re-bending of formed sections, protective caps on connector ends where provided, and dry storage. Handling requirements specific to your assemblies are agreed with the job documentation.
