SSMA Male RF Coaxial Connector – Compatible with RG316/U Cable, up to 30 GHz
Model: SSMA-J3
The SSMA-J3 from SIPU is a Male SSMA RF Coaxial Connector specifically designed for termination with RG316/U coaxial cable. As a miniaturized version of the SMA connector, the SSMA series offers a compact form factor while maintaining excellent electrical and mechanical performance for high-frequency RF applications.
Compliant with IEC 60169-18, the SSMA-J3 features a gold-plated brass body, gold-plated bronze center conductor, and PTFE dielectric, ensuring low VSWR, low insertion loss, and stable signal transmission up to 30 GHz. Its lightweight and compact design makes it ideal for high-density and space-constrained RF systems.
The SSMA-J3 is widely used in base stations, RF cable assemblies, test and measurement instruments, telecommunication systems, and other microwave and digital communication equipment where reliability and performance are critical.
