    摘要: A communications device may include an In-phase (I) circuit having an In-phase modulator and mixer circuit, and an I power amplifier circuit coupled thereto, the I circuit configured to modulate and amplify a digital baseband I signal to generate an amplified I signal, and a Quadrature (Q) circuit having a Q modulator and mixer circuit, and a Q power amplifier circuit coupled thereto, the Q circuit configured to modulate and amplify a digital baseband Q signal to generate an amplified Q signal separate from the amplified I signal. The communications device may include a processor configured, for example, to selectively switch the digital baseband signal and the digital baseband Q signal between the I and Q signal inputs to provide selective phase shifting for the digital baseband I and Q signals. For example, the controller may selectively phase shift the digital baseband I and Q signals, and control the I and Q power amplifier circuits to vary an amplitude of the amplified I and Q signals.

    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 hearing aid has improved immunity to RF electromagnetic interference produced from wireless communications devices. A microphone receives audio signals from the environment. Audio circuitry is connected to the microphone and amplifies the audio signals. A speaker is connected to the audio circuitry and directs the audio signals into an ear canal of the user of the hearing aid. The audio connection lines connect the microphone and audio circuitry and the speaker and audio circuitry. A filter is connected into each of the audio connection lines and operative for reducing the RF coupling from a wireless communications device.

    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.
