Claim 18:
19. The method of claim 17, wherein the generating the respective compensation value for each gain setting of at least the portion of the plurality of gain settings is during a calibration phase, and further comprising:
maintaining the present output valley level of the amplitude envelope of the signal output substantially at the predetermined target valley level during an operating phase subsequent to the calibration phase by:
monitoring the digital amplitude signal to detect a present gain setting of the plurality of gain settings;
identifying a present compensation value as associated with the present gain setting, the present compensation value being one of the plurality of compensation values stored in the lookup table;
generating a compensation signal based on the present compensation value; and
outputting the compensation signal to a supply modulator circuit to generate the supply voltage at the respective compensated supply voltage level corresponding to the present compensation value.
