A device and a method for an amplifier having reduced intermodulation (IM) distortion output products are presented. An amplifier has an output, and at least one of a gate bias input and a drain supply input. The amplifier is configured to receive an input signal and output an amplified signal at the output of the amplified. An input is configured to receive an envelope signal. The input is connected to the at least one of the gate bias input and the drain supply input and the envelope signal is at least partially determined by an attribute of the input signal to the amplifier. A controller is configured to modify at least one of an amplitude and a phase of the envelope signal to reduce a magnitude of an intermodulation distortion product of the amplifier.
