Abstract
A simplified analytic expression is developed to predict the noise performance of HEMT gate mixers. A nonlinear model of noise was given for theoretical study and implanted in ADS simulator. A contribution of each noise source was presented in this paper. This study is applied to a millimeter-wave HEMT gate mixer. The LO, RF and IF frequencies chosen for this test were 24.5, 28.5 and 4 Ghz respectively. Good agreement is obtained between analytical calculation, simulation and experimental noise figure in single side band NFSSB.
