Abstract
A radio frequency (RF) communications system, which includes power amplifier (PA) control circuitry and PA bias circuitry, is disclosed. The PA control circuitry identifies a selected communications mode of the RF communications system and a target output power from RF PA circuitry. The PA control circuitry selects a PA bias level of a driver stage of the RF PA circuitry and a PA bias level of a final stage of the RF PA circuitry based on the selected communications mode and the target output power. The PA bias circuitry establishes a PA bias level for the driver stage and a PA bias level for the final stage based on the selected PA bias levels of the driver stage and the final stage, respectively.
