Abstract

A load having the conjugate impedance of the signal generator to which it is connected receives the maximum amount of power and is said to be matched on the conjugate-image basis. This method of impedance matching, when applied to active and passive four-terminal networks, is shown to be especially suitable for determining the limits of power amplification or loss. In contrast, an analysis on the usual image basis gives these results only if the image impedances happen to be pure resistances. The maximum power gain of a given network and the impedance terminations for achieving it are derived and are expressed in-concise form. The effects of impedance mismatching are likewise treated.
