1.85mm Vertical Solderless PCB Connector DC–67 GHz VST-CPM185F-01

P/N: VST-CPM185F01

  • For short vertical PCB launches
  • Two-hole flange for stable board attachment
  • Solderless design for repeatable installation and replacement
  • Well suited to 67 GHz test boards and fixtures
  • Supports precision microwave applications through 67 GHz
Engineering Note
VST-CPM185F-01 is a 1.85mm vertical solderless PCB connector for precision board launches. It is built around a compact two-hole flange structure and 1.85mm jack interface, with 50 ohm impedance, DC–67 GHz frequency range, and VSWR 1.45 max. This configuration is intended for microwave and millimeter-wave boards where vertical transition quality, repeatable assembly, and low discontinuity at the launch are required.
