The SMA connector(SubMiniature version A) is a 50 ohm coaxial
connector. It is visually similar to an F type connector that is
commonly used for audio/video communication, but has different
dimensions, mechanical properties and is used for different
applications such as RF communications up to 18 GHz. Due to its
construction, SMA connectors provide a strong and durable connection
that minimizes reflections, limiting attenuation, and makes it a
great choice when working with microwave frequencies.
SMA Male Connector
The SMA male
connector is identified by inside 1/4″-36 threads and a 5/16″ hex
nut. A standard polarity connector will have a male pin.
