110 GHz Differential RF Probe for On-Wafer and PCB Validation VST-110G-GSSG

P/N:  VST-110G-GSSG-XXX

  • For differential PCB and wafer-level measurements
  • GSSG geometry for cleaner mixed-mode characterization
  • Precision tip symmetry for repeatable high-frequency contact
  • Well suited to 6G, radar, and high-speed SerDes evaluation
  • Supports differential applications through 110 GHz
Engineering Note
VST-110G-GSSG-XXX is a DC–110 GHz GSSG RF probe for on-wafer measurement of high-frequency differential circuits. It uses a GSSG tip configuration, 1.00mm female interface, and 45-degree connector angle, with pitch options from 40 μm to 3 mm. This configuration is intended for wafer-level characterization where stable contact, wide bandwidth, and differential probing capability are required. :contentReference
