Abstract
A power amplifier module includes a power amplifier including an amplifier including an amplifying transistor configured to amplify an input signal, and output an output signal, and a bias circuit including a bias transistor configured to provide a bias current to the amplifying transistor; and a controller configured to provide a control current to the bias transistor, wherein the controller is configured to vary the control current based on a temperature of the amplifying transistor.
