    • A power amplifier comprises a common source amplification stage and a first common gate amplification stage. The common source amplification stage includes a common source transistor for receiving a radio frequency (RF) input signal via a gate. The first common gate amplification stage is connected in cascode between a variable supply voltage source and the common source amplification stage, and amplifies an output of the common source amplification stage. The first common gate amplification stage includes a first common gate transistor connected in cascade with the common source amplification transistor; and a first gate bias controller configured to generate a first divided voltage based on a variable supply voltage of the variable supply voltage source, and to supply a first gate bias voltage generated by buffering the first divided voltage to a gate of the first common gate transistor.
