摘要 |
A power amplifier controller for detecting saturation of the power amplifier (203) and corrects the automatic output control voltage (231) to avoid any further saturation. A detector (211) detects the power of the radio frequency (RF) output signal (211) and generates a signal (229) correlated to the detected power. Comparator (217) compares changes in that signal (229) to changes in the voltage of the AOC signal (231). The comparator (217) generates a signal (233) correlated to saturation of the power amplifier (203) for a DSP (223). The DSP (223) checks the status of this signal (233). Upon detecting saturation, an algorithm contained within the DSP methodically reduces the voltage of the AOC signal (231) until there is a change in the power of the RF output signal (211). |
