World Record: Saga University and JAXA Achieve 120 Gigahertz Amplification with Diamond Semiconductors

Saga University and the Japan Aerospace Exploration Agency (JAXA) have announced a monumental breakthrough in the field of next-generation electronics. The joint research group successfully demonstrated amplification in the microwave and millimeter-wave bands at 120 Gigahertz using a diamond high-frequency semiconductor device. This achievement represents a world-class level of performance, pushing the boundaries of what is possible in signal processing speed and power.

Diamond is often referred to as the "ultimate semiconductor material" due to its superior physical properties. Compared to traditional materials like Silicon or Gallium Nitride, diamond offers exceptional thermal conductivity and a higher breakdown voltage. These characteristics allow diamond devices to operate at higher power levels and frequencies without overheating, a critical factor for the future of telecommunications.

The newly developed technology is specifically optimized for next-generation communication infrastructures, such as 6G base stations and satellite communication devices. Beyond its speed, diamond's inherent resistance to radiation makes it an ideal candidate for the harsh environment of outer space, a key interest for JAXA.

Following this research success, the focus is now shifting to commercialization. "Diamond Semiconductor," a startup venture originating from Saga University, is set to begin shipping samples of these high-performance devices starting in January. This marks a significant step towards the practical adoption of diamond semiconductors in the global market.
