What Does SubMiniature Version A Connector (SMA Connector) Mean?
An SubMiniature version A (SMA) connector is a coaxial cable connector developed in the 1960s as a semi-precision minimal connector interface with a screw-type coupling mechanism for coaxial cables. This connector features only 50 ohms of impedance and a 1/4-inch-36-thread-type coupling mechanism. It offers excellent performance from 0 to 18 GHz and is usually used as an RF connector for antennas.
Techopedia Explains SubMiniature Version A Connector (SMA Connector)
The SMA connector is considered a semi-precision, sub-miniature and high-frequency connector that is rated to deliver reliable broadband performance from DC to 18 GHz, with a constant impedance of 50 ohms and low reflection. The main features of this connector are its high mechanical strength and high durability, as evidenced by its robust-looking metal construction.
