Abstract:
A calibration device for a power amplifier includes a calculation unit, a first storage unit and a multiplier. The calculation unit is utilized for generating a calibration factor according to a value of a characteristic parameter of the power amplifier. The first storage unit coupled to the calculation unit, for storing the calibration factor. The multiplier is coupled to the first storage unit and a baseband unit, for multiplying a baseband signal outputted from the baseband unit by the calibration factor for generating an input signal to the power amplifier.
