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.

摘要： The invention relates to a system and method for attenuating harmonics in output signals. In the system, an electronic circuit for reducing harmonics of an output signal from a power amplifier in a transmission circuit for a wireless communication device is provided. The circuit comprises: a printed circuit board (PCB); a power amplifier for generating an output signal; and a circuit implemented on the PCB connected to an output terminal of the power amplifier for the output signal. The circuit comprises a first filtering stage; a delay element; and a harmonic filter. The delay element is located between the harmonic filter and the output terminal and the delay element provides a timing delay in the output signal through at least one 0 ohm-rated component. Also, the harmonic filter is a low pass filter having a frequency cut-off point that attenuates first order harmonics of the output signal.
