Evaluation of 28 nm CMOS Receivers at 183 GHz for Space-borne Atmospheric Remote Sensing

This letter discusses the capability of 28 nm CMOS technology to implement receivers at the 183 GHz band enabling the potential of future radiometers for monitoring atmospheric water vapor. To demonstrate the potential of 28 nm for constructing receivers at these frequencies, a prototype LNA and downconverter chip is demonstrated and measurements of both gain and noise performance are presented.
