A 300GHz CMOS Transceiver Aiming for Long-Range Sub-Terahertz Communications

A 44 GHz frequency band from 252 GHz to 296 GHz has been identified for telecommunications. This frequency band is a part of the 300 GHz band which is expected to be utilized for ultra-high speed wireless communication towards 6G. In this presentation, the relationship between radio frequency and communication distance is explained, and the necessity of a communication system using a phased array is clarified. Finally, a 300 GHz CMOS wireless transceiver that can be used as an element of this phased array and can transmit data rates of up to 80 Gb/s will be presented.
