ABSTRACT:
A predistorter linearizer includes a magnitude distorter and a phase distorter, each including variability to provide a desired magnitude characteristic and phase characteristic. The method comprises adjusting a circuit to provide a desired magnitude characteristic and adjusting the circuit to provide a desired phase characteristic. A signal is modified using the desired magnitude and phase characteristics to produce a signal for amplification. The modification of the signal is offset by any modification resulting from the amplification, resulting in a more linearized amplifier output.
