67 GHz GS RF Probe for On-Wafer and PCB Characterization VST-67G-GS

P/N: VST-67G-GS-XXX

  • For single-ended PCB and wafer-level testing
  • GS geometry for clean ground-signal probing
  • Fine-pitch tips for dense pad layouts
  • Well suited to mmWave device and SI validation
  • Supports precision measurements through 67 GHz
Engineering Note
VST-67G-GS is a DC–67 GHz GS RF probe for single-ended on-wafer measurement and high-frequency PCB characterization. It uses a GS tip configuration, a 1.85 mm female connector, and a 45-degree connector angle. The datasheet gives a standard 100 μm to 1250 μm pitch range with custom options available, making it suitable for mmWave device characterization, coplanar structure testing, and compact high-frequency validation setups.
