SMA connector


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.
