Power amplifiers (PAs) are vital components in many communication systems. To be transmit-ted wirelessly, a signal must be amplified with high fidelity so as to account for attenuation through the channel or propagation medium. The linearity of a PA response constitutes an important factor that ensures signal integrity and reliable perfor-mance of the communication system.
