SMA connectors are precision connectors for microwave applications up to 18 GHz. These connectors are high quality screw-on coupling connectors with defined maximum torque and feature high reliability, long service life, high mechanical stability and excellent electrical characteristics, in particular high return loss.
The impedance is controlled at 50Ω. Connector styles are available for flexible, conformable and semi-rigid cable types. SMA applications include communications, satellite and test equipment.
