An amplifier system having one or more signal paths. Each path includes a linear amplifier and a Class G Type amplifier. The linear amplifier receives an input signal bearing phase and amplitude information. The Class G Type amplifier receives an envelope signal which tracks the anticipated output signal, plus a DC offset. The output of the Class G Type amplifier is coupled to provide the VCC reference for the linear amplifier. High frequency performance and high efficiency are obtained.
