摘要：
A power amplifier system includes a first power detector configured to detect a forward power output of a power amplifier, the first power detector configured to provide a first power detector output and an adjustable load coupled to the output of the power amplifier and configured to receive the first power detector output, the adjustable load configured to provide an adjustable impedance at the output of the power amplifier in response to one of the output of the power amplifier and the first power detector output.
