ABSTRACT:
A predistortion linearizer for predistorting a radiofrequency (RF) signal includes a first third-order predistortion linearizer having an input for receiving the RF signal, and a second third-order predistortion linearizer connected in cascade with the first linearizer, whereby fifth order nonlinearities are introduced into a cascaded, predistorted RF output signal. Cascading additional third-order linearizers similarly provides higher-order linearizers.
