SMPM® Interconnect Series

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:

  • Antennas
  • Broadband
  • Wireless
  • Military
  • Instrumentation


  • DC - 65 GHz frequency range
  • 50 Ω impedance
  • Blindmate configuration
  • MIL-PRF-39012 compliant
  • Ability to withstand radial/axial misalignment
  • Board-mount, field replaceable, bullets, hermetic, and cable connector configurations
  • Custom connectors available
