Methods and apparatus for aligning output power levels of a transmitter having a power amplifier adapted to operate in first and second operational modes. According to an exemplary embodiment, the transmitter includes a power alignment circuit configured to execute a power alignment algorithm. The power alignment algorithm is operable to align an output power level of the power amplifier when configured in the first operational mode with an output power level of the power amplifier when configured in the second operational mode. When the power amplifier is switched from the first operational mode to the second operational mode, the power alignment circuit references a power table having power entries that ensure that the output power level in the second operational mode is aligned with the output power level in the first operational mode. So that power control tolerances are satisfied for changes in power levels before and after a mode switch, one or more additional power control settings can be inserted in the power table.
