    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. A processor selectively switches the digital baseband I 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.

    摘要： A portable audio device having reduced sensitivity to RF interference over a predetermined frequency range from an adjacent mobile wireless communications device may include a portable housing, a battery carried thereby, a recharging power input connected to the battery, a digital signal input, and an audio analog signal output. A digital-to-analog converter (DAC) may be carried by the portable housing and powered by the battery for converting a selected digital audio file from a memory into an analog audio signal. An audio analog amplifier may be connected between the DAC and the audio analog signal output. A first RF filter(s) may be connected to the recharging power input, and a second RF filter(s) may be connected to the audio analog signal output, both for reducing RF interference over the predetermined frequency range from the adjacent mobile wireless communications device.
