ABSTRACT:
Disclosed is a method to operate a RF transmitter, and an RF transmitter constructed to operate in accordance with the method. The method includes determining a transmitter output power and varying a level of a signal at a transmitter phase modulator according to the transmitter output power so as to increase the level of the signal as the transmitter output power increases and to decrease the level of the signal as the transmitter output power decreases. In the preferred embodiment the method further includes adjusting the current consumption of a plurality of components of an RF transmitter chain in accordance with at least one of the level of the signal and the gain of the stage.
