摘要： A system for controlling amplifier power is provided. The system includes a voltage envelope detector that receives a voltage signal and generates a voltage envelope signal. A current envelope detector receives a current signal and generates a current envelope signal. A power amplifier level controller receives the greater of the voltage envelope signal and the current envelope signal, such as by connecting the output of the voltage envelope detector and the current envelope detector at a common point and conducting the high frequency current components to ground via a capacitor. A power amplifier level control signal is then generated based on the voltage drop across the capacitor.
