The SMP interface is a subminiature interface in the same scale as MMCX connectors but offers a frequency range of DC to 40 GHz. It is commonly used in miniaturized high frequency coaxial modules and is offered in both push-on and snap-on mating styles.

The available detent systems, full, limited, and smooth bore, provide respective levels of engagement/disengagement forces. This family of interconnects addresses small package design needs. It can be utilized as a highly shielded interconnect for high data rate applications or in a board-to-board system using a floating bullet adapter. This floating bullet provides a link between mated pairs compensating for both radial and axial misalignment.

Available in a cable-to-board mated pair, the plug side can be provided in either right angle or straight with termination capability to either 0.047” or 0.086”, semi-rigid or conformable coax. The receptacles are designed for surface, through hole, or end launch mounting.
