Abstract
A predistortion circuit and method provides signals to oppose and cancel an anticipated phase and frequency distortion in a coupled electrical system. The predistortion circuitry includes first and second subcircuits which include opposing diodes, providing 180 degree out-of-phase and in-phase signals to produce second, third and higher order predistortion outputs.
