This work advances the capabilities of accurately quantifying the microwave noise temperature that exits port one of a two-port active device when port two is terminated with a complex load of known temperature. This noise temperature is of interest when characterizing and designing field-effect transistor (FET)-based cold noise sources or active cold loads that can be used as radiometer calibration reference standards. Unlike prior efforts, noise wave theory is used herein to derive an… CONTINUE READING
