  • Abstract
    An analytical analysis of noise figures in HEMT mixers is presented. Improved method was developed to evaluate the noise correlation. A simplified analytical expression for noise figure of HEMT mixer was also derived. The contribution of each noise source at various frequencies was represented in a phasor form to permit physical understanding of noise mechanism. The modeled noise figure was compared with the measured data, yielding a good agreement.
