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.
