1. A power amplifier system comprising:
a power amplifier including an input configured to receive a radio frequency input signal and an output configured to output an amplified radio frequency signal; and
a distortion network electrically coupled to either the input or the output of the power amplifier, the distortion network including a plurality of channelized resistors, each of the channelized resistors having a relationship of current vs. drain-to-source voltage that forms a substantially hyperbolic curve.
