摘要： A mobile communication device has a power amplifier and a power pack. The power pack includes a charge storage component, a first pair of taps connected to the charge storage component for supplying power to components of the mobile communication device and a second pair of taps connected to the charge storage component for supplying power to the power amplifier, the second pair of taps located, when the power is installed in the mobile communication device, more proximate to the power amplifier than the first pair of taps. With the second pair of taps positioned more proximate to the power amplifier, the power amplifier current loop that includes the multi-tap power pack may be made smaller. One benefit of a smaller power amplifier current loop may be reduced emission of RF interference signals.

摘要： A power distribution network includes multiple charge storage components and multiple charging circuits to control the charging and discharging of the charge storage components, which may comprise a battery and a supercapacitor. By appropriate arrangement and selection of the storage components, ripple in the power supply voltage, whose propagation to other components relying on the power distribution network may cause an audible buzz, may be significantly reduced. Additionally, appropriate arrangement and selection of the storage components, electromagnetic interference may also be significantly reduced.

摘要： A mobile wireless communications device includes a wireless local area network (WLAN) radio configured to generate a WLAN transmit signal, and a Bluetooth radio configured to generate a Bluetooth transmit signal. A circulator is coupled downstream of an antenna. A transmit path couples the WLAN radio and the Bluetooth radio to the circulator such that the WLAN radio and the Bluetooth radio are capable of transmitting simultaneously. In addition, a receive path also couples the WLAN radio and the Bluetooth radio to the circulator such that the WLAN radio and the Bluetooth radio are capable of receiving simultaneously.
