This paper presents a 1-THz radiating array using IHP 130-nm SiGe process. It is based on a highly-scalable 2D structure that uses a square grid of slots to simultaneously (1) maximize and synchronize the fundamental oscillation (ƒ<inf>0</inf>=250 GHz) and 4<sup>th</sup>-harmonic generation (4ƒ<inf>0</inf>=1 THz) of a large array of transistors, (2) synthesize standing-wave patterns with near-field cancellation at ƒ<inf>0</inf>, 2ƒ<inf>0</inf> and 3ƒ<inf>0</inf> and efficient radiation at 4ƒ<inf>0</inf>. The compact design enables implementation of 42 coherent radiators on a 1-mm<sup>2</sup> area. The chip consumes 1.1-W DC power and generates 80-µW total radiated power with 13-dBm EIRP.
