Detailed Product Description

SMA RF coaxial connectors introduction:

Type SMA RF coaxial Connector is one Kind of 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 widely used in connect with the RF cables or micro-strip line in RF circuit of the WLAN 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.
