SMA (SubMiniature version A) connectors are semi-precision coaxial RF connectors developed in the 1960s as a minimal connector interface for coaxial cable with a screw type coupling mechanism. The connector has a 50 Ω impedance. SMA is designed for use from DC to 18 GHz, but is most commonly encountered with WiFi antenna systems and USB Software Defined Radio dongles.

SMA connectors can be visually confused with the standard household 75 ohm Type F Coax Connector (Diameters: Male 7⁄16″ (11 mm) circular or hex; Female 3⁄8″ (9.5 mm) external threads), as there is only about a 2mm difference overall in the specifications. Type F can only be mated with SMA if there is an adapter (possibly coupled with a Gender Changer).

Using a threaded interface, SMA 50 Ohm connectors are semi-precision units that provide excellent electrical performance from DC to 18 GHz and outstanding mechanical durability. SMA connectors feature stainless steel or brass construction and ¼ – 36 threaded coupling, which offers high performance in a compact design.

For phase array radar, test equipment, ILS landing systems and other instrumentation using phase matching techniques, SMA interconnects offer a precise and simple means of phase adjustment for microwave devices. Built in accordance with MIL-C-39012 and CECC 22110/111, SMA connectors can be mated with all connectors that meet these specification mating diameters regardless of manufacturer.
