Abstract
The present disclosure relates to an RF power amplifier (PA) power supply that includes a series pass circuit coupled across a direct current (DC)-to-DC converter to receive a power supply input signal, such as provided from a battery, to provide a power supply output signal to at least a first RF PA based on an output setpoint. Control circuitry selects between a switching supply operating mode and a non-switching supply operating mode based on the output setpoint. During the switching supply operating mode, the DC-to-DC converter provides the power supply output signal and during the non-switching supply operating mode, the series pass circuit provides the power supply output signal.
