SMA SERIES - RF CONNECTORS

SMA stands for Sub Miniature Version A and was developed in the 1960´s. They are semi precision that provide excellent
electrical performance from 0 up to 18GHz, due to its threaded interface. They are primarily used where higher frequencies and
miniaturization are needed, since they are compact in size and mechanically have outstanding durability.
They are built in accordance with IEC 169-15 and MIL-C-39012, and are available for a variety of flexible and semi rigid
cables, including the .086 and .141 types, that allows customer flexibility in their project design.
Brass SMA connector are also available in nickel or gold plating providing a cost effective solution when stainless steel is not required.
