Abstract :
A method for the evaluation of the noise figure in matrix amplifiers has been developed. The amplifier noise figure is derived as a function of the noise characteristics of the active devices and circuit parameters. A simple expression in closed form is obtained. The results of the model are in good agreement with experimental data.<>
