67 GHz Differential RF Probe for On-Wafer and PCB Validation VST-67G-GSSG

P/N: VST-67G-GSSG-XXX

  • For differential PCB and wafer-level testing
  • GSSG geometry for cleaner mixed-mode measurements
  • Tight phase matching for low-skew signal capture
  • Well suited to 112G SerDes and 5G/6G evaluation
  • Supports differential applications through 67 GHz
Engineering Note
VST-67G-GSSG is a DC–67 GHz GSSG RF probe for differential on-wafer measurement. It uses a GSSG tip configuration, 1.85mm female interface, and 45-degree connector angle, with standard pitch coverage from 100 μm to 1250 μm. This configuration is intended for wafer-level differential measurements where low loss, stable contact, and repeatable high-frequency probing are required.
