Patent ID: 8126036

Claim:
A method for linearizing output signals from an inherently non-linear transceiver device during calibration, said method comprising steps of amplifying signals received through an antenna from a transmitter of the transceiver, filtering the amplified signals using a low pass filter, converting the filtered signals to digital signals using an analog to digital converter, producing post-distorted in-phase and quadrature-phase output signals based upon the digital signals, communicating the post-distorted in-phase and quadrature-phase output signals to a predistorter, linearizing output from the transmitter using the predistorter, and decreasing gain control of a power amplifier to 0 and then increasing gain control slowly until it reaches a determined back-off point, and after reaching the back-off point, activating a receiver of the transciever and, thereby, causing the receiver to be compressed due to cross talk and intermodulation distortion.
