SMA Male RF Coaxial Connector – Compatible with RG316/U Cable
Model: SMA-J3
The SMA-J3 from SIPU is a Male SMA RF Coaxial Connector designed for reliable termination with RG316/U coaxial cable. As part of the widely adopted SMA connector family, it features a compact threaded interface that delivers excellent electrical performance and mechanical stability for high-frequency RF applications.
Manufactured with a gold-plated brass body, gold-plated brass center conductor, and PTFE dielectric, the SMA-J3 provides low VSWR, low insertion loss, and long service life. Its straight-type SMA male interface ensures secure mating and stable signal transmission in demanding RF environments.
The SMA-J3 is commonly used in wireless communication systems, telecommunication infrastructure, RF modules, network equipment, and test & measurement instruments, where consistent impedance matching and reliable RF connectivity are required.
