SMA Connectors RF (Sub Miniature Version A) connectors are precision sub Miniature connectors primarily used for higher frequencies with excellent electrical performance from DC through 18 GHz. SMA connectors are primarily used where trends toward higher frequencies, Miniaturization, and SMA connectors are built in accordance with MIL-C-39012 and are available for a variety of flexible and semi-rigid cables. Brass SMA connectors provide a cost effective solution for applications where stainless steel construction is not required.
SMA launchers are the preferred connection element for varied microwave circuits, including hermetically sealed designs. The SMA line covers a huge variety of applications such as Test+Measurement, mobile communications, avionics, etc.
