Product Overview

Leveraging the deep R&D heritage of Xi'an Jiaotong University, our waveguide probes are designed for high-frequency measurements with precision manufacturing that ensures perfect matching between the probe and the waveguide 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 series uses low-loss dielectric materials to effectively reduce insertion loss and improve measurement accuracy. Its unique coplanar waveguide design maintains stable electrical performance across a wide bandwidth, making it an ideal choice for research institutions and production lines.
