- Keysight, NTT, and NTT Innovative Devices set a new world record of 280 Gbps data rate using sub-THz frequencies.
- The breakthrough was achieved in the 300 GHz band, surpassing the previous 240 Gbps milestone.
- Advanced digital predistortion techniques were crucial in optimizing signal integrity and minimizing distortion.
Keysight Technologies, Inc. (KEYS, Financial), in collaboration with NTT Corporation and NTT Innovative Devices Corporation, has set a new world record for data transmission speed, achieving 280 Gbps using sub-terahertz (THz) frequencies. This milestone in wireless communication was accomplished utilizing Keysight's cutting-edge Vector Component Analyzer (VCA) and NTT's J-band Indium Phosphide (InP)-based power amplifier with digital predistortion (DPD) capabilities.
The successful demonstration occurred in the 300 GHz frequency band, where the power amplifier achieved a saturated output of +9.1 dBm, enabling the record-setting 280 Gbps data rate at 0 dBm output power. The advanced digital predistortion technology was pivotal in overcoming amplifier non-linearities, ensuring high-fidelity signal generation.
Hirokazu Takenouchi, Vice President and Head of NTT Device Technology Laboratories, highlighted the importance of collaboration with Keysight, which provided innovative solutions that were instrumental in reaching these new heights in data rate capabilities. Akimasa Kaneko from NTT Innovative Devices emphasized the role of InP technology in achieving this remarkable throughput.
Joe Rickert, Vice President of Keysight's High Frequency Center of Excellence, stated that this accomplishment underscores Keysight's leadership in supplying advanced test and measurement solutions that unlock the potential of sub-THz frequencies for the development of 6G technologies.
The details of this achievement will be presented at the International Microwave Symposium (IMS) 2025 on June 19 in San Francisco, California.
