Patent ID: 8233866

Claim:
A wireless device comprising: an antenna; Radio Frequency (RF) circuitry coupled to the antenna and operable to receive a baseband signal, to convert the baseband signal to an RF signal, and to couple the RF signal to the antenna; baseband processing circuitry coupled to the RF circuitry, wherein the baseband processing circuitry is operable to: produce the baseband signal, such that it is pre-distorted to compensate for antenna input impedance and RF circuitry signal distortion characteristics, in which the baseband signal that is pre-distorted is based upon calibration operations; and initiate the calibration operations when an operational value of the wireless device compares unfavorably to at least one operational threshold, in which the calibration operations include application of a fixed current to at least one gain adjustable element of the RF circuitry and application of different current values than the fixed current at respective plurality of intervals.
