Formulas for the noise figure, and the minimum uoise figure of a multi-link distributed amplifier have been developed. In addition, a relatively simple approximation formula has been devised that predicts the minimum noise figure of a practicaf amplifier design with good accuracy np to frequencies of 9 GHz. Finafly, after the dependence of the noise characteristics on the circnit parameters is discussed, the noise figures of a 2-18-GHz three-link module are compnted and compared witfr those measured on an actuaf amplifier. The measured data across the 2-18-GHz band compare favorably with the computed results. Measurements and theory agree that onfy small improvements in noise figure may he achieved, when noise matching the module's input impedance.
