"avoids energy-intensive digital-to-analog/ analog-to-digital converters by: performing complex signal analog processing/ constructing signals directly in RF using 3 synchronized sub-transmitters... antenna-to-bits receiver uses hierarchical analog demodulation to peel apart data layers before digitization, consuming only 230 mW (avoids overheating)... fabricated using standard 22-nm silicon-on-insulator... data centers, smartphones (6G without draining batteries in minutes), AI edge computing, autonomous vehicles"
