Abstract
The present disclosure includes a discussion of a power amplifier controller which powers up a power amplifier (203) without a substantial burst of frequency noise. The controller has a RF output power detector (211) which generates a signal (229) correllated 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).
