The SMA (Sub Miniature version A) connector range offers semi-precision, 50-ohm impedance, and a 0.25 - 36 threaded coupling. These compact connectors provide high performance and are frequently used as a standard for antennas, devices, and various medical applications. They are also known as F type coaxial connectors and are suitable for relatively small electronic equipment.
