SMA Cable Assembly
Custom SMA and RP-SMA coaxial cable assemblies for antennas, embedded wireless products, RF modules, production test fixtures, and compact instruments.
SMA Cable Assembly Applications
SMA assemblies are usually selected when buyers need a compact threaded RF interface with controlled impedance, repeatable mating, and practical routing inside a small enclosure.
Embedded Wireless
SMA pigtails and panel-mount leads for IoT gateways, routers, telemetry modules, and radio devices.
Antenna Connections
50 ohm antenna jumper cables with straight, right-angle, bulkhead, and reverse-polarity SMA options.
Test Equipment
Repeatable lab and production-test interconnects where connector quality and length control matter.
Compact Instruments
Small-diameter coax routing for medical, industrial, and handheld equipment with limited enclosure space.
SMA Builds Fail When the RF Details Are Treated Like Ordinary Wiring
In our RF cable work, the most common buyer-side issue is an incomplete SMA callout: the drawing says "SMA male" but omits standard versus reverse polarity, cable family, frequency band, and panel hardware. That small gap can change the connector, the crimp die, the strip dimension, and the RF test plan.
Our engineering review ties the SMA connector choice to the underlying coaxial cable construction, then validates workmanship against IPC-A-620 expectations and applicable UL 758 wire/cable material requirements when the end product needs safety-file alignment.
- SMA gender, polarity, orientation, and panel-mount hardware
- Cable family or target outer diameter if routing space is fixed
- Frequency band, acceptable insertion loss, and any VSWR target
- Installed length, tolerance, bend radius, and strain-relief need
- Environmental exposure: indoor, outdoor, vibration, oil, cleaning agents, or temperature
- Label format, packaging, drawing revision, and lot traceability requirements
SMA Manufacturing Capabilities
These are the details we confirm before we quote, fixture, and release a custom SMA cable assembly.
Controlled SMA Cable Assembly Process
The process is built around repeatable termination geometry, not just connector availability.
RFQ Review
We check the SMA interface, cable family, frequency band, routing space, and whether the program needs standard electrical testing or RF validation.
Termination Setup
Strip length, braid foldback, ferrule crimp, center-contact soldering, and heat-shrink dimensions are locked before pilot production.
First Article
The first build is inspected for connector seating, dielectric condition, pull strength, length, labels, and drawing match before scaling.
Production Test
Every assembly receives continuity verification; RF-sensitive builds can add insertion loss, return loss, and visual connector inspection records.
Custom SMA Coaxial Cable Assembly for RF Buyers
OurPCB manufactures SMA cable assemblies for procurement engineers who need more than a catalog jumper. We support custom cable lengths, compact pigtails, panel-mount leads, right-angle exits, RP-SMA antenna cables, and mixed-end RF assemblies that connect SMA to BNC, MCX, MMCX, FAKRA, or board-level interfaces.
Compared with larger RF builds such as RG213 cable assembly, SMA work is often limited by enclosure space and connector handling. A few tenths of a millimeter in strip length can affect dielectric support, braid capture, or contact seating. That is why our pilot builds record the connector part number, cable family, strip setup, crimp tool, visual criteria, and electrical test method before repeat production.
Buyers often combine this page with our broader coaxial cable assembly, RF connector cable assembly, MCX cable assembly, or MMCX cable assembly services when a product uses several RF interfaces in the same harness kit.
SMA Cable Assembly FAQs
Answers to common RFQ-stage questions before sourcing a custom SMA coaxial cable.
SMA cable assemblies are used for 50 ohm RF connections in antennas, wireless modules, test equipment, embedded radios, routers, telemetry devices, and compact instruments that need a small threaded coaxial interface.
Yes. We build standard SMA and reverse-polarity SMA cable assemblies. The RFQ should clearly state SMA or RP-SMA, connector gender, straight or right-angle orientation, and whether a bulkhead nut and washer are required.
The best cable depends on routing space, loss target, bend radius, and environment. RG178 and RG316 are common for compact pigtails, RG174 is used for flexible low-profile routing, and larger cable families may be selected when lower loss is more important than diameter.
Standard production includes 100% electrical continuity testing. For RF-critical programs, we can add insertion loss, return loss, or VNA-based checks tied to the customer's frequency band and acceptance criteria.
Simple SMA prototypes can often move quickly when connectors and cable are available. Custom connector sourcing, special jacket materials, molded strain relief, or RF test fixtures can extend lead time, so we confirm timing after BOM and drawing review.
