Abstract
A detuned composite amplifier includes a nonlinear drive function (22) that has a phase that varies with the composite amplifier output voltage amplitude. The nonlinear drive function (22) is configured to transform the output voltage transition point of the prior art into an extended output voltage transition region to increase the efficiency of the composite amplifier.
