  • Abstract
    Modern microwave communication systems rely heavily on the linearity of output stages incorporating GaAs FET power amplifying devices. This letter describes a system for the automatic nonlinearity measurement in such devices of gain and phase angle as functions of input power level and frequency, with results leading to significantly improved system performance.
