Features

The SMP has a subminiature interface suitable for miniaturized high frequency coaxial modules up to 40Ghz. SMP’s can be used as PC board to board interconnects by connecting a male SMP on each of the PC boards by a female-to-female adapter.
Mesa currently offers two types of male center contact: SMP male limited detent for a positive locking with a medium retention and SMP male full detent for a positive locking with a maximum retention. In board mount applications the limited detent is usually selected whereas full detent is mostly used for cable connections where higher forces are desirable.
