SMPM® Interconnect Series

SMPM Connectors

Carlisle Interconnect Technologies (CarlisleIT) designed the SMPM® connector product line to further improve package density of RF/Microwave systems. The SMPM interface is about 30% smaller than its predecessor, the SMP connector. Now an industry standard (as outlined in the MIL-STD-348 document) for RF/Microwave applications, the SSMP interface has enabled design engineers to increase performance and complexity of their designs while simultaneously improving upon their form factor.

The SMPM interconnect system relies on a floating female-to-female adapter, commonly referred to as a “bullet”, to enable stacking of boards equipped with an SSMP male PCB connector. The durable construction and ability to tolerate radial and axial misalignment allows for a blindmate interconnect solution that can withstand multiple engagement/disengagement cycles without degradation in electrical performance.

Due to its high-frequency performance along with a blindmate configuration, the SMPM connector is a standard interface in optical networking components, specifically 40 G and 100 G Modulator and Driver amplifiers.
