42.5 Ohm 2.92mm Jack Solderless PCB Connector DC–40 GHz VST-CPM292F-09

P/N: VST-CPM292F-09

  • For low-impedance PCB launch structures
  • Optimized for 85 ohm differential environments
  • Solderless format for repeatable board-side installation
  • Well suited to 40 GHz test boards and fixtures
  • Supports compact microwave assemblies through 40 GHz
Engineering Note
VST-CPM292F-09 is a 42.5 ohm 2.92mm jack solderless PCB connector intended for low-impedance board launches. It covers DC–40 GHz with VSWR ≤ 1.30 and uses a compression-style solderless mounting structure with a two-hole flange. This configuration is suitable for microwave and millimeter-wave boards where a lower target impedance is required together with repeatable mechanical attachment and controlled transition geometry.
