Abstract:
A switch mode power supply converter and a parallel amplifier are disclosed. The switch mode power supply converter is coupled to a modulated power supply output and the parallel amplifier has a parallel amplifier output coupled to the modulated power supply output. Further, the parallel amplifier has a group of output stages, such that each output stage is directly coupled to the parallel amplifier output and each output stage receives a separate supply voltage.
