Enable precise movement in limited space using high-flex rg-58 SMA cable assemblies

24 July 2026

Amphenol RF has introduced its new in-series SMA cable assemblies built on high-flex RG-58 cable. The durable SMA interface combined with the flexibility of the RG-58 cable type ensures consistent mechanical integrity in demanding applications with limited space. These assemblies are ideal for automation, communication systems and radio frequency (RF) laboratory environments.

High-flex RG-58 cable features a fine-wire stranded copper center conductor with a tinned copper braid Source: Amphenol RFSource: Amphenol RF shield. These 50-ohm cable assemblies offer reliable electrical performance up to 3 GHz and are engineered for applications requiring a tight bend radius and repeated cable movement. The cable maintains consistent electrical performance when flexed, making the assemblies highly suited for dynamic routing and offering support for a wide range of integration requirements. They are available in standard lengths of 12 inches to 3 meters.

These SMA assemblies join a growing portfolio of pre-configured coaxial cable assemblies that offer a high level of flexibility and reliability in 50-ohm applications in dynamic or space-constrained environments.
