Differential Coaxial Probe

High-performance coaxial probe for millimeter-wave and terahertz measurements with low loss, high repeatability and wide bandwidth.

  • Frequency RangeDC – 220 GHz
  • Interface Type0.6mm, 0.8mm, 1.0MM coaxial connectors
Product Overview

Leveraging the deep R&D heritage of Xi'an Jiaotong University, our coaxial probes are designed for high-frequency measurements with precision manufacturing that ensures perfect matching between the probe and the coaxial interface. Ideal for on-wafer RF/microwave testing, optoelectronic device characterization, and high-speed interconnect signal integrity verification. Each probe is rigorously calibrated for outstanding repeatability and durability, with a range of standard options and customization services to meet diverse customer needs.

The GSSG probe is manufactured with a special MEMS semiconductor chip process, achieving differential crosstalk suppression of over 30 dB, a world-leading level.
