SMA is an acronym for SubMiniature version A. It uses a threaded interface. Semi-precision 50 Ω SMA connectors provide excellent electrical performance from DC to 18 GHz although some 'general purpose' versions will not perform as well. SMA connectors are compact in size and mechanically have outstanding durability. SMA connectors can be mated with other SMA and APC-3.5 mm connectors.
SMA is available both in Standard and Reverse Polarity (RP) versions. Reverse polarity is a keying system accomplished with a reverse interface, and ensures that reverse polarity interface connectors do not mate with standard interface connectors. Most manufactures accomplish this by inserting female contacts into plugs and male contacts into jacks. Other manufacturers use reverse threading to accomplish reverse polarity keying.
