ABSTRACT:
In one implementation, the present invention includes a diode device to receive an incoming radio frequency (RF) signal to be amplified in a gain device of an amplifier and to provide a pre-distorted signal. Based on this pre-distorted signal, the gain device can output an amplified RF signal having substantial linearity to the incoming RF signal.
