1. An apparatus comprising:
a voltage regulator circuit configured to provide an adjustable output voltage at an output;
a plurality of power amplifiers each comprising a respective voltage supply line coupled to the output of the voltage regulator circuit, each of the plurality of power amplifiers configured to amplify one or more signals for transmission via at least one antenna;
a plurality of precharge voltage regulator circuits, at least one of the plurality of precharge voltage regulator circuits configured to have an adjustable precharge output voltage; and
a plurality of capacitors each configured to be selectively operably coupled to the output of the voltage regulator circuit, each of the plurality of capacitors coupled to a respective precharge voltage regulator circuit of the plurality of precharge voltage regulator circuits.
