Keysight and Virginia Diodes Develop 1.5 THz Measurement Solution for Chalmers

Keysight Technologies, Inc. of Santa Rosa, California and reported that it has collaborated with Virginia Diodes, Inc. (VDI) to develop a 1.5 THz measurement solution for Chalmers University of Technology. Chalmers University is a leading research university located in Gothenburg, Sweden.

The solution that the companies created is already in operation at Chalmers’ national laboratory for terahertz characterization. The system provides network and spectrum analysis for research on new materials, devices, and circuits for applications at the micro-, millimeter- and sub-millimeter-wave frequencies.

Chalmers’ researchers are working in the terahertz gap between infrared light and radio waves. The Keysight Technologies measurement equipment enhances the Chalmers work with free-space, on-wafer, and waveguide measurements in the terahertz gap. The researchers built the system using the Keysight PNA-X microwave network analyzer, which covers 10 MHz to 67 GHz. The system reaches 1.5 THz with the aid of external extension modules from VDI.

The PNA family from Keysight Technologies is the first to provide both network and spectrum analysis capability that reaches into the terahertz range. The ability to make multiple measurements through one set of connections and access both capabilities in a single test setup saves time and enhances insight.

“Working in concert with VDI, we’re proud to be Chalmers’ solution provider of choice for terahertz network and spectrum measurements,” said Gregg Peters, vice president of Keysight’s Aerospace & Defense Solutions Group. “As we keep reaching higher in frequency, our history of innovation will continue to enable new breakthroughs in science and technology.”

Tom Crowe, president and CEO of VDI added, “It’s another example of our ongoing work to open the terahertz spectrum for commercial and scientific applications.”
