A Highly Linear Digital Detector for Noise Parameter Measurements at Microwave Frequencies

Improvements in the determination of the 4 real parameters Fmin, Rn, Gopt, Bopt which completely describe the noise behaviour of a linear two-port are presented. An accurate noise parameter measurement method, the seven-state-method, is developed. Contrary to previous works this method is mainly based on cold noise power measurements. An additional measurement of the input admittance of the DUT with a network analyser as needed for other techniques is not necessary. In addition, the noise power measurement accuracy is improved by the development of a highly linear digital detector.
