SMA uses a threaded interface. 50 Ω SMA connectors are semi-precision, subminiature units that provide excellent electrical performance from DC to 18 GHz. These high-performance connectors are compact in size and mechanically have outstanding durability. It can yield the * value in your microwave system. Among t*ical applications are components, such as dividers , mixers , amplifiers , trimmers and attenuators. SMA cinnectors are also used to provide interconnections from printed circuit board striplines to coaxial cable.

SMA is available both in Standard and Reverse Polarity.
