Abstract
An amplifier system is provided that switches between operation in a polar mode and a signal restoration mode based on a characteristic of an input signal relative to a threshold level. The system includes a correction path that mitigates distortion and out-of-band (OOB) emissions in the polar mode and provides at least a substantial portion of the amplified output signal in the signal restoration.
