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 mobile wireless communications device includes a housing, antenna, and circuit board carried by the housing and having radio frequency (RF) circuitry operative with the antenna for receiving and transmitting RF signals through the antenna. A power amplifier is connected within a transmission line for amplifying RF signals to be transmitted over the transmission line to the antenna. An antenna switch is connected to the antenna and RF circuitry. An RF shield surrounds the power amplifier and antenna switch and isolates the power amplifier and antenna switch from the antenna and RF circuitry. A low pass filter is connected to the power amplifier and antenna switch for reducing any RF coupling of voltage standing waves of upper harmonic frequencies from the power amplifier into the antenna switch through the RF shield while maintaining transmission of signals through the transmission line at a desired fundamental frequency.

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. Optionally, an electromagnetic interference filter may be placed between the charge storage components.

摘要： A communications device, in one aspect as a portable wireless communications device, includes an in-phase modulator and power amplifier that receives a baseband I signal and modulates and amplifies the I signal. A quadrature modulator and power amplifier receives a baseband Q signal and modulates and amplifies the Q signal. A power combiner sums and outputs the I and Q signals. An I demodulator circuit receives a signal fed back from the I power amplifier and demodulates the fed back signal to produce demodulated I signals. A Q demodulator circuit receives a signal fed back from the Q power amplifier and demodulates the fed back signal to produce demodulated Q signals. A processor compares the digital, baseband I and Q signals with a demodulated I and Q signals to compensate for amplitude, frequency and phase modulation errors.

摘要： A mobile wireless communications device includes a housing and circuit board carried by the housing and having RF circuitry comprising at least one RF component and plurality of other components mounted on the circuit board. An RF metal shield is secured to the circuit board and surrounds and isolates the at least one RF component and plurality of other components within the RF metal shield. An RF absorber is positioned adjacent an area of the RF component that radiates energy to aid in reducing energy radiated from the RF component into the RF metal shield.
