Abstract:
Embodiments for at least one method and apparatus of a voltage supply are disclosed. One voltage supply apparatus includes a voltage supply, a plurality of power amplifier (PA) decoupling circuits, and a plurality of power amplifiers. Each PA decoupling circuit is connected to the voltage supply and provides a filtered voltage supply to a corresponding one of the plurality power amplifiers. Each PA decoupling circuit configured to suppress noise of the provided filtered voltage supply below a threshold at one or more selected frequencies, wherein the suppression is provided by the PA decoupling circuit operating in conjunction with at least one other of the plurality of PA decoupling circuits.
