    摘要： An amplifier module comprises an amplifier with an output and a coupling element for receiving a signal at the output. It also comprises a control input for receiving a control signal and a power detector which can be changed over and is intended to determine a power signal from the signal. The power detector which can be changed over is coupled to the control input and is set up in such a manner that a dynamic range of the power detector can be changed on the basis of the control signal.
