PCB Insider manufactures custom RF cable assemblies for antenna systems, radios, telecom cabinets, test equipment, medical electronics, defense hardware, and integrated box-build programs. We focus on impedance continuity, connector discipline, shielding control, and repeatable production instead of treating RF interconnects like generic jumper cables.
RF cable assemblies fail for reasons that do not show up on a simple continuity test. Connector mismatch, route length, shielding practice, bend damage, and assembly geometry all affect how the final interconnect behaves in the field. If the program depends on stable radio-frequency performance, the cable assembly has to be specified as part of the signal path rather than bought like a generic wiring item.
That is why our process starts with the actual use case. We review impedance family, cable construction, connector interface, installation constraints, and validation expectations before we release material. Teams working with radio-frequency systems, coaxial cable structures, and environments shaped by electromagnetic interference already know that bench success does not guarantee production stability.
We also help buyers translate performance language into sourcing decisions. If your team is balancing connector style, return-loss targets, and installation risk, background concepts such as VSWR and insertion loss matter because they affect real signal margin. For electronics programs that also need board-level or system integration support, we can align the RF assembly with our PCB assembly and box build assembly workflows.
Purpose-built RF and coaxial interconnect support for teams that need real production control around signal integrity, connector fit, shielding, and documentation.
We build custom RF cable assemblies for low-frequency signal paths through multi-GHz interconnects used in telecom, instrumentation, medical electronics, aerospace, and defense systems. Capability ranges depend on the selected cable and connector family, not on generic marketing claims.
Assemblies can be configured with SMA, SMB, SMC, BNC, TNC, N-type, MMCX, MCX, U.FL, FAKRA, Mini-FAKRA, and application-specific panel or bulkhead interfaces. We review mating cycles, sealing needs, torque practice, and field-service expectations before release.
RF assemblies are built around impedance continuity, insertion-loss targets, and acceptable return-loss behavior. We help buyers avoid the common mistake of treating an RF cable like a standard low-voltage jumper with no attention to mismatch or connector geometry.
Cable, braid, foil, jacket, and connector termination choices are aligned to the actual EMI environment. That matters for radios, antennas, imaging systems, GNSS modules, and mixed-signal equipment where shielding errors create unstable field performance.
We support fixed, flexing, routed, panel-mounted, and sealed RF cable assemblies with strain relief, heat-shrink boots, labels, branch control, and packaging matched to installation risk. Mechanical abuse is a common source of RF failure, so routing and bend limits are treated as part of the design.
Every released assembly is tied to controlled drawings, traveler instructions, approved BOMs, and inspection records. That gives OEM buyers cleaner first-article approval, more stable recurring production, and fewer ambiguities during ECOs or supplier transitions.
We support engineering samples, NPI lots, pilot builds, and repeat production. The same process logic used on early prototypes is carried forward so the validated sample does not drift when volume demand arrives.
PTFE, FEP, PE, low-smoke jackets, armored constructions, and temperature-resistant options are selected based on actual service conditions. Outdoor telecom, vehicle electronics, and lab equipment all impose different demands on flex life, abrasion resistance, and dielectric stability.
For system assemblies, RF coax can be combined with power, Ethernet, or control wiring in one managed build package. That reduces sourcing fragmentation when your box build or electronics program needs both high-frequency and conventional interconnects together.

A release process designed to reduce mismatch risk, prototype drift, and sourcing surprises in RF interconnect programs.
We review connector families, cable type, target impedance, route length, bend constraints, and the expected signal path so the assembly is evaluated as part of the system, not as a commodity cable line item.
Material choice is matched to frequency, insertion-loss tolerance, movement, sealing, temperature, and field-handling risk. This avoids overbuying on cost while still protecting the link budget and service life.
Prototype units are assembled with controlled preparation, termination, torque practice, and visual inspection. If your program needs it, we also support first-article evidence tied to drawing revision and approved materials.
Assemblies are checked for continuity, shorts, insulation integrity where applicable, dimensional accuracy, mating fit, and any customer-defined RF checks. Validation depth is tied to application risk rather than a one-size-fits-all checklist.
After approval, we fix strip lengths, connector prep, shield termination details, labeling, and packaging controls into a repeatable traveler. This is what prevents prototype-to-production drift.
Production lots ship with the documentation package needed for receiving, integration, and future reorder control. That matters when RF assemblies become long-life service parts rather than one-off lab cables.
Typical use cases where buyers need more than a generic coax jumper.
RF jumper cables, antenna leads, small-cell interconnects, and cabinet wiring for wireless and telecom systems that need stable insertion loss and reliable connector retention.
Bench and production-test assemblies for signal generators, analyzers, RF fixtures, calibration setups, and lab instrumentation where repeatable mating and known loss behavior are essential.
FAKRA and Mini-FAKRA style RF links for cameras, GNSS, telematics, V2X, and infotainment hardware that need vibration-aware routing, connector coding, and controlled assembly geometry.
RF and coaxial assemblies for imaging, monitoring, and diagnostic electronics where low-noise behavior, controlled documentation, and repeatability matter more than the lowest unit price.
Ruggedized RF assemblies for radar, communications, avionics, and payload systems that need shielding discipline, durable materials, and stronger traceability than commodity coax products can provide.
Internal RF coax routing combined with PCB assemblies, power wiring, and enclosure integration for OEM products that need one supplier to manage electrical and mechanical interfaces together.
Commercial-intent buyers usually care less about theory and more about whether the build will survive sourcing, assembly, and field use without unexpected RF behavior.
The cable datasheet matters, but connector choice, assembly geometry, and route length all affect the final signal path. Buyers that optimize only cable cost often end up paying for rework or poor field performance later.
Tight bends, poor strain relief, overtightened connectors, and improper routing damage coax performance long before the cable looks obviously broken. A serviceable design needs mechanical discipline, not just electrical specifications.
A hand-built prototype that performs well in the lab is not enough. Production documentation, fixture control, and inspection criteria are what make repeat orders behave like the approved sample.

Learn MoreA standard coax cable assembly may only be specified by length and connector type, while an RF cable assembly is usually selected and built around impedance continuity, insertion-loss limits, return-loss expectations, shielding strategy, and mechanical installation risk. In practice, RF assemblies need tighter system-level thinking than commodity coax jumpers.
Yes. We support both 50 ohm and 75 ohm cable-assembly families. The correct choice depends on the connected equipment, connector ecosystem, and signal path design. Mixing them without a clear system reason usually creates avoidable mismatch risk.
Yes. Prototype and NPI support is a core use case. We can work from released drawings, interface notes, BOMs, or an early-stage concept package, then help refine the assembly so the prototype is manufacturable and repeatable in later production.
The fastest quoting package includes the target application, cable type or performance target, impedance, connector callouts, assembly length, any bend or routing limits, labeling needs, expected environment, validation requirements, and annual or lot quantity. A drawing or photo of the installed condition also helps prevent quoting mistakes.
Yes. Every lot can include continuity and insulation-related checks as appropriate, plus dimensional and mating verification. When the program requires deeper RF validation, we align the acceptance plan to your application rather than claiming one generic test method covers every RF assembly.
Yes. Many customer programs need RF interconnects, PCB assemblies, and enclosure wiring together. Managing those interfaces with one manufacturing partner reduces fit issues, schedule friction, and responsibility gaps during integration.
Send your drawing, connector list, target application, or installed routing photo and we'll review the cable strategy before quoting. That shortens revision loops and helps you avoid preventable RF sourcing mistakes.
