METHOD AND APPARATUS FOR CONTROLLING A SUPPLY VOLTAGE TO A POWER AMPLIFIER
摘要
<p>A supply voltage to a power amplifier is controlled. A signal at a single point in a power amplifier is detected (600). A signal parameter is determined (602) for the detected signal. The signal parameter is compared (604) to at least one predetermined limit. This comparison result is used to determine (606) whether to adjust (608) a supply voltage to the power amplifier. The signal parameter is, for example, an average power or a peak-to-average power ratio.</p>
