OPTIMUM NOISE PERFORMANCE OF MULTITERMINAL AMPLIFIERS,

Abstract

A measure is determined of the optimum noise performance of a linear multiterminal-pair amplifier. It is shown that the optimum noise performance, achieved by imbedding a multiterminal-pair source and a multiterminal-pair amplifier in an arbitrary lossless network, can also be achieved by imbedding the source in an arbitrary lossless network to reduce it to a one-terminal-pair source and then using it to drive an arbitrary lossless reduction of the amplifier. The optimization procedure is extended to multifrequency networks coupled in an arbitrary manner by a lossless nonlinear device that obeys the Manley-Rowe formulas. In this context, the optimum noise performance of an ideal (lossless) double-sideband parametric amplifier is examined for both the cases in which the noises in the two sidebands are uncorrelated and partially correlated.
