 RF CONNECTORS		 systlog2.gif (3643 Byte)
Description

SMA connectors are precision subminiature connectors primarily used for higher frequencies with excellent electrical performance from DC through 18 GHz. The SMA connectors are built in accordance with MIL-C-39012 and are available for a variety of flexible and semi-rigid cable assemblies. Brass SMA connectors are available and provide a cost effective solution for applications where stainless steel construction is not required.
