    Abstract: The present disclosure relates to a single switching power supply that may either provide envelope power to a first RF power amplifier during a first operating mode, or simultaneously provide envelope power to the first RF power amplifier and to a second RF power amplifier during a second operating mode. In one embodiment, the single switching power supply and the first and second RF power amplifiers may be used in a multiple-input multiple-output (MIMO) RF communications system. As such, during the first operating mode, the first RF power amplifier may transmit a first RF output signal to a first antenna, and during the second operating mode, the first RF power amplifier may transmit the first RF output signal to the first antenna and the second RF power amplifier may transmit a second RF output signal to a second antenna, which may provide diversity.

    Abstract: Radio frequency (RF) power amplifier (PA) circuitry and a PA envelope power supply are disclosed. The RF PA circuitry receives and amplifies an RF input signal to provide an RF output signal using an envelope power supply signal, which is provided by the PA envelope power supply. The RF PA circuitry operates in either a normal RF spectral emissions mode or a reduced RF spectral emissions mode. When reduced RF spectral emissions are required, the RF PA circuitry operates in the reduced RF spectral emissions mode. As such, at a given RF output power, during the reduced RF spectral emissions mode, RF spectral emissions of the RF output signal are less than during the normal RF spectral emissions mode. As a result, the reduced RF spectral emissions mode may be used to reduce interference between RF communications bands.

    Abstract: A battery assembly for a mobile communication device includes a battery having a mounting surface, wherein a capacity of the battery increases with temperature. The battery assembly further includes a power amplifier assembly mounted to the mounting surface of the battery. The power amplifier assembly includes a power amplifier in thermal communication with the battery and a circuit board configured to receive the power amplifier, wherein the power amplifier is mounted to the circuit board. Generated heat from the power amplifier is transferred to the battery in order to increase the capacity of the battery in a given temperature environment.
