Aspects of a method and system for extending dynamic range of an RF signal are provided. In this regard, an amplitude signal that is representative of an amplitude of a pair of baseband signals may be generated, an amplitude of the generated amplitude signal may be modified according to a function; and an amplitude of the baseband signals may be modified according to an inverse of the function. The modifications may adjust the peak-amplitude-to-average-amplitude ratio of one or more signals. An intermediate signal may be generated from the modified baseband signals and the amplitude of the intermediate signal may be amplitude modulated by the intermediate signal. The intermediate signal may be amplitude modulated by controlling a gain of a power amplifier. The intermediate signal may be amplitude modulated by controlling a current source and/or voltage source supplying power to a power amplifier. |
