Research Progress of the Circuits for the THz Systems

Abstract

The development of the terahertz (THz) integrated circuits is an important aspect for the THz applications. This paper reviews the recent research progress of THz circuits developed in State Key Lab. Of Millimeter Waves (SKLMW) of China. The multipliers, mixers, and systems over 200 GHz with GaAs technology has been demonstrated with good performance. Compared with that, the VCOs and mixers over 300 GHz with Silicon-based technology has also been demonstrated for better cost reduction and integration. The research aspect would benefit for the future THz system improvement.
