摘要：Some embodiments discussed relate to an apparatus comprising a power amplifier module. The power amplifier module includes a plurality of sensors, and a first digital communication port configured to provide a monitor signal from at least one of the plurality of sensors. The apparatus includes a transceiver module coupled to provide an signal to an input of the power amplifier the transceiver module including a second digital communication port configured to receive the monitor signal from the first digital communication port, a processing unit configured to generate at least one of a bias control signal and a back-off signal dependent upon the monitor signal, and a power controller to receive the at least one of bias control signal and the back-off signal and provide at least one further input signal to the power amplifier based on at least one of the bias control signal and the back-off signal.
