SSMA-JB2 Male RF Coaxial Connector – Compatible with 2# Semi-Rigid/Semi-Flexible Cable, up to 30 GHz

Model: SSMA-JB2

The SSMA-JB2 from SIPU is a Male SSMA RF Coaxial Connector designed for direct termination with 2# semi-rigid or semi-flexible coaxial cables. As a miniaturized version of the SMA connector, the SSMA series offers a compact footprint while maintaining excellent electrical and mechanical performance for high-frequency RF applications.

With its gold-plated brass construction, PTFE dielectric, and precision mating interface, the SSMA-JB2 delivers low VSWR, low insertion loss, and stable signal transmission up to 30 GHz. Its compact and lightweight design makes it especially suitable for high-density RF assemblies and space-constrained systems.

The SSMA-JB2 is widely used in communication base stations, RF cable assemblies, test and measurement instruments, electronic modules, and aerospace and microwave systems, where reliability and high-frequency performance are critical.
