A 300GHz CMOS Transceiver Targeting 6G

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 toward 6G. In this talk, an overview of ultra-wideband wireless communication using the 300 GHz band is given and the necessity of a communication system using a phased array is clarified. Finally, a 300 GHz CMOS wireless transceiver, which can be used as an element of this phased array and can transmit data rates of up to 80 Gb/s, is introduced.
