SMPM Connectors
Amphenol CIT designed the SMPM Connector product line to further improve package density of RF/ Microwave systems. With an interface about 30% smaller than its predecessor, the SMPM Connector is now an industry standard (as outlined in the MIL-STD-348 document) for RF/microwave applications and has enabled design engineers to increase design performance and complexity while improving form factor.
The durable construction and ability to tolerate radial and axial misalignment allows for a blindmate interconnect solution capable of withstanding multiple engagement/disengagement cycles without degradation in electrical performance.
Due to its high-frequency performance and blindmate configuration, the SMPM Connector is a standard interface in many applications including:
