All-digital transmitters (DTXs), leveraging custom low-VT RF-power technologies [2], offer substantial energy savings by using switching operation and completely eliminating quiescent currents. In addition, DTXs enable extreme bandwidths since their circuit topology is frequency-agile up to the (power combining) output-matching network. To date, no high-power, high-efficiency DTX solutions have been reported that offer RF-power levels required for mMIMO base stations
