Abstract:
1. A wireless device comprising: a Radio Frequency (RF) circuitry coupled to receive a baseband signal, to convert the baseband signal to an RF signal, and to transmit the RF signal; a 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 matching impedance and signal distortion characteristics of the RF circuitry, and wherein the baseband signal that is pre-distorted is based upon calibration operations that is to be initiated when an operational characteristic of the wireless device compares unfavorably to an 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; and a monitoring circuitry coupled to the RF circuitry and to the baseband processing circuitry to monitor the operational characteristic of the wireless device.
