The present disclosure relates generally to systems and methods for
combining stepped drain bias control with digital predistortion for a
power amplifier. In one example, the method includes receiving an input
associated with a transmit power level of a transmitter in a wireless
terminal and selecting a predefined drain bias setting for a power
amplifier of the wireless terminal based on the input. A predefined
predistortion setting for the power amplifier corresponding to the
selected predefined drain bias setting is identified. A drain of the
power amplifier is set to the selected predefined drain bias setting, and
the identified predefined predistortion setting is applied to a signal
prior to directing the signal to the power amplifier.
