A method to reduce transmitted output power and the battery consumption is provided. This involves first determining the required output level. The amplitude of the input signal provided to a PA driver may be based on the required output power level. This amplitude may be set by a PGA. A number of cascode bias signals are also provided to the PA driver. These cascode bias signals are based on the required output power level as well. Reducing the cascode bias signals by enabling/disabling circuits within the PA driver allows power consumption of the wireless device to be reduced.
