Abstract
An apparatus for generating a plurality of power supply signals for a plurality of power amplifiers configured to amplify radio frequency transmit signals includes a first power supply circuit configured to generate a first power supply signal and a different second power supply signal. The first power supply circuit is configured to provide the first power supply signal to a first output path and the second power supply signal to a second output path. Further, the apparatus includes a second power supply circuit configured to generate a third power supply signal. Still further, the apparatus includes a switching circuit configured to couple the second power supply circuit to the first output path in a first operating mode to provide a first combined power supply signal at an output of the first output path based on the first power supply signal and the third power supply signal.
