Nonlinear Extrinsic Noise Model for HEMT Mixer Suitable for CAD Software

Faiza Amrouche, Rachid Allam


In this paper, two temperatures equivalent noise model was used to predict the noise figure performance and was applied to HEMT gate mixer in which a contribution of each noise source is implanted in ADS simulator. The extracted non-linear elements of equivalent model by measurements are interpolated to provide a description of the HEMT's nonlinearities in a CAD software. The accuracy of the non-linear noise model and noise figure simulation has been verified and we obtain a good agreement between measured and simulated noise figure results.
