SMA Cable Assemblies
Versatile, high-frequency solutions engineered for precision RF performance in a wide range of commercial and industrial systems
Overview
Amphenol RF's SMA cable assemblies are designed to deliver reliable, high-performance RF connectivity in demanding environments. Built around the widely-used SMA connector interface, these assemblies offer excellent electrical performance up to 18 GHz, with precision test cable options supporting even higher frequencies. Available in a wide variety of configurations and cable types, these assemblies are ideal for both general-purpose RF applications and high-frequency test environments.
These 50 ohm assemblies are manufactured using industry-standard flexible, semi-rigid, and conformable coaxial cables. All standard SMA cable assemblies are hi-pot and continuity tested, while our precision test cables are sweep tested and serialized for advanced performance assurance. Standard configurations are available off-the-shelf, and custom designs can be developed to suit specific needs.
Features and Benefits
- Broad selection of standard lengths and connector combinations
- Support for frequencies up to 18 GHz (up to 27 GHz with precision test cables)
- Durable brass and stainless steel connector options
- Hi-pot and continuity tested (sweep tested for precision versions)
- Compact threaded coupling ensures secure mating in vibration-prone environments
- Variety of cable types, including RG-58, RG-316, RG-142, and low loss options
- Available IP67 sealed versions for ruggedized applications (as listed on product pages)
Key Technical Details
Amphenol RF SMA cable assemblies utilize a threaded interface that ensures consistent performance and resistance to vibration. These assemblies are well-suited for RF testing, wireless infrastructure, and custom antenna solutions. The SMA interface supports excellent VSWR and low insertion loss, particularly when used with matched cable types and proper installation practices.
Assemblies using stainless steel connectors are rated for higher mating cycles and environmental resilience, while brass options offer cost-effective solutions for commercial deployments. The SMA product line is engineered for both system integration and critical RF testing environments.
Applications
- RF test and measurement
- Antenna and wireless module connections
- Instrumentation and diagnostics
- Cellular infrastructure and DAS (Distributed Antenna Systems)
- Aerospace and defense systems
