Keysight, NTT Corporation and NTT Innovative Devices announced a groundbreaking world record in data rate achieved using sub-THz frequencies.
According to the companies, the test achieved a 280 Gbps data rate — the highest data rate reported to date in the 300 GHz band, suitable for 6G networks, a press release stated. The output power reached 0 dBm, approximately 8 times higher than that of previous records (−9 dBm8).
“This 280 Gbps world record underscores Keysight’s commitment to providing the advanced test and measurement solutions critical for unlocking the potential of sub-THz frequencies for 6G,” said Joe Rickert, Vice President and Head of Keysight’s High Frequency Centre of Excellence.
NTT designed and developed a new amplifier integrated circuit equipped with a wideband impedance matching circuit and a low-loss combiner circuit. Keysight contributed with its Vector Component Analyser (VCA, built on the latest N524XB series PNA-X Microwave Network Analysers equipped with digital predistortion techniques.
“This accomplishment marks a significant milestone in developing the broadest frequency bandwidth amplifier, enhancing energy efficiency and linearity, and addressing industry challenges,” added Akimasa Kaneko, Executive Vice President of NTT Innovative Devices, Photonic Components Business Group.
Looking ahead, the companies plan to explore the application of feedforward distortion compensation using distortion models. According to them, this would enable simpler and more flexible signal generation without the need for test signal feedback.
