SMK Series 2.92 mm Connectors & Adpaters

Cinch Connectivity Solutions features their SMK series 2.92 mm connectors designed for high frequency transmission applications

Image of Cinch Connectivity Solutions' SMK Series 2.92 MM ConnectorsCinch Connectivity Solutions' 2.92 mm connector provides an excellent solution for demanding applications requiring high frequency transmission. Although similar to the SMA interface, a smaller internal body diameter (2.92 mm) and air dielectric provide a higher cutoff frequency and other key advantages:

  • Precision manufacturing allows superior electrical performance to 40 GHz
  • Female contacts have a unique three-slot construction, which enhances connectivity by creating a more rugged connector while reducing the chance of intermittent connections
  • Precise assembly tooling assures excellent, repeatable contact, and support bead location on cabled connectors
  • Connector mating interface per MIL-STD-348
  • Mating interface control provides consistent electrical performance
  • The plug connector VSWR is 1.20 max to 40 GHz and a 12 inch SMK plug-to-plug cable assembly performs better than 1.35 VSWR to 40 GHz
  • The field replaceable jacks are teamed with a high quality hermetic seal feed through for use in sealed circuit modules
  • The 2.92 mm plug interface employs more precise dimensions than an SMA and uses a shorter snub nose male pin such that the connector bodies align before the contacts engage
