A 44 GHz frequency band from 252 GHz to 296 GHz has been identified for communications. This frequency band is part of the 300 GHz band, which is expected to be utilized for ultra-high speed wireless communication toward 6G. In this letter, we will discuss the requirements for ultra-wideband wireless communications in the sub-terahertz range, including the 300 GHz band, and clarify the necessity of a communication system based on phased arrays. Finally, a 300 GHz CMOS wireless transceiver capable of transmitting data rates of up to 80 Gb/s that can be utilized as an element of this phased array is presented.
