Abstract
A predistortion linearizer for predistorting a radio frequency(RF) signal includes a power divider, an even order harmonics generator and a predistortion component producer. The power divider divides the RF signal into a first and a second RF signals. The even order harmonics generator, responsive to the second RF signal, generates one or more even order harmonics of the fundamental frequencies. And, the predistortion component producer produces one or more odd order harmonics from the fundamental frequencies and the even order harmonics to provide a predistorted RF signal including the fundamental frequencies and the odd order harmonics. The power divider divides the RF signal into first and second RF signals and delays the first RF signal.
