SMA Coaxial Connectors

RF coaxial SMA male crimp straight
connector for RG174 RG316 cable

TYPE SMA is a Kind of RF coaxial connectors that is widely applied, with small-sized thread coupling. Characteristic impedance is 50Ω.The characteristic of connectors is in wide frequency range、excellent performance、high reliability. They are used in connection with RF cable or micro-strip line in RF circuit of the WIAN SYSTEM、controlled program、microwave equipment and the digital communication system. The frequency can be up to 18GHz by using semi-rigid or semi-flex cable.
