    • 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.
    • 本公开涉及单个开关电源,其可以在第一操作模式期间向第一RF功率放大器提供包络功率,或者在第二操作期间向第一RF功率放大器和第二RF功率放大器同时提供包络功率 模式。 在一个实施例中,单个开关电源和第一和第二RF功率放大器可以用在多输入多输出(MIMO)RF通信系统中。 因此,在第一操作模式期间,第一RF功率放大器可以将第一RF输出信号发送到第一天线,并且在第二操作模式期间,第一RF功率放大器可以将第一RF输出信号发送到第一天线, 第二RF功率放大器可以将第二RF输出信号发送到可以提供分集的第二天线。

    • An over-voltage detection and correction system for a transmitter of a mobile terminal that accounts for battery droop during a transmit burst is provided. In general, prior to ramp-up for a first transmit burst, a voltage of the battery of the mobile terminal at a no-load condition is measured. After ramp-up for the transmit burst, the voltage of the battery is measured at full-load, and a current provided to a power amplifier of the transmitter at full-load is detected. Based on the measured voltage of the battery at no-load, the measured voltage of the battery at full-load, and the detected current provided to the power amplifier at full-load, a resistance of the battery is determined. The resistance of the battery is thereafter used to compensate for battery droop during over-voltage detection and correction for one or more subsequent transmit bursts.
    • 提供了一种用于在发送突发期间考虑电池下降的移动终端的发射机的过电压检测和校正系统。 通常,在第一发射突发的斜坡上升之前,测量移动终端的电池在空载状态下的电压。 在发送突发的斜坡上升之后,在满负载时测量电池的电压,并检测在满载时提供给发射机的功率放大器的电流。 基于空载电池的测量电压,满载时电池的测量电压和满载时提供给功率放大器的检测电流,确定电池的电阻。 此后,电池的电阻用于补偿过电压检测期间的电池下降和针对一个或多个后续发射脉冲串的校正。
