Abstract: Circuitry, which includes a PA power supply and RF PA circuitry, is disclosed. The RF PA circuitry includes a group of RF PAs and a group of PA decoupling circuits. The group of RF PAs includes a first RF PA and a second RF PA. The group of PA decoupling circuits includes a first PA decoupling circuit and a second PA decoupling circuit. The PA power supply provides a first PA power supply output signal to at least one of the group of RF PAs and to at least one of the group of PA decoupling circuits. The first PA decoupling circuit is coupled across the first RF PA, is programmable, and at least partially decouples the first RF PA from other circuitry. The second PA decoupling circuit is coupled across the second RF PA and at least partially decouples the second RF PA from other circuitry.
