Abstract :
We present experimental and theoretical results on sub-harmonic mixing of THz radiation at 639 GHz with radiation at 213 GHz (both being high above fT) in an antenna-coupled silicon CMOS detector with a fundamental antenna resonance at 213 GHz. The measurements are analyzed in the context of distributed resistive mixing in the channels of the field-effect transistors.
