Molex SMA connectors are high-performance subminiature connectors for microwave frequencies. The threaded coupling insures uniform contact of the outer conductors, which enables the SMA to minimize reflections and attenuation at higher frequencies while providing a high degree of mechanical strength and durability. Molex offers SMA connectors in brass, beryllium copper, and stainless steel materials. Molex has a wide range of designs including high-performance, optimized SMA connectors, operating to 27 GHz.
