1. An envelope elimination and restoration (EER) radio frequency (RF) transmitter comprising: a data source input adapted to receive a data signal to be transmitted; an envelope signal path comprising a power supply modulator; a phase signal path comprising a local oscillator; a power amplifier at the terminal end of the envelope and phase signal paths that recombines the two signals for RF transmission; and a pre-emphasis filter in the envelope signal path adapted to pre-emphasize the envelope signal before it reaches the power supply modulator.
