<p>A power amplifier controller which powers up a power amplifier (203) without a substantial burst of frequency noise. The controller has an RF output power detector (211) which generates a signal (229) correlated to the power level of the power amplifier (203). This signal (229) is compared (215) to a reference signal (213) to determine if the power amplifier (203) is active. The signal (227) generated by this comparator (215) is used to determine the voltage level of the Automatic Output Control (AOC) signal (231).</p> |
