The SMA (Sub-Miniature Type A) connector is a widely used 50Ω RF interface with a threaded coupling, typically operating from DC to 18 GHz and up to 26.5 GHz for precision variants. Its compact size and stable performance make it suitable for cable assemblies, PCB interfaces, test equipment, and general microwave systems. Gwave has developed multiple kinds of SMA connector options to support these application needs.
