Adaptive Cancellation of Intermodulation Distortion by Harmonic Feedback Controlled Bias Voltage Tuning

A system linearization assembly generally includes a delay device that receives an input signal from a signal source and delays the input signal by a predetermined delay function. An attenuation device receives a modified output signal from a signal modifying device, wherein the output signal is based on the input signal and includes a time varying parameter representing a plurality of frequency components including at least one component caused by non-linear intermodulation distortion. The attenuation device attenuates the output signal by a factor that is equal to at least one parameter of the modifying device. A computing device compares the attenuated output signal with the delayed input signal to obtain a resultant signal that includes the component caused by non-linear intermodulation distortion. A detection device detects at least one parameter of the resultant signal. Based on the detected parameter, a controller facilitates a modification of the component.
