Pushed to the limit: A CMOS-based transceiver for beyond 5G applications at 300 GHz

Scientists at Tokyo Institute of Technology (Tokyo Tech) and NTT Corporation (NTT) have developed a novel CMOS-based transceiver for wireless communications at the 300 GHz band, enabling future beyond-5G applications. Their design addresses the challenges of operating CMOS technology at its practical limit and represents the first wideband CMOS phased-array system to operate at such elevated frequencies.
