Abstract
There are disclosed various methods and apparatuses for providing power to a set of power amplifiers. In some embodiments the method comprises obtaining first transmission parameters associated with a first transmit signal, selecting one or more output voltage values on the basis of the first transmission parameters, controlling a multi-level power source to generate one or more output voltages on the basis of the one or more output voltage values, multiplexing based on the first transmit signal between two or more of the output voltages and a first supply voltage terminal of a first power amplifier, and amplifying the first transmit signal with the first power amplifier.
