Summary:The utility model relates to a single-point modulation wireless communication device. The single-point modulation wireless communication device comprises an audio and baseband signal processing unit, a frequency synthesizer (PLL), a voltage controlled oscillator (VCO), and a reference clock (VT-TCXO). The single-point modulation wireless communication device is characterized in that signals that have been processed by the audio and baseband signal processing unit are modulated via the reference clock (VT-TCXO), and then are modulated by the frequency synthesizer (PLL) onto the voltage controlled oscillator (VCO). The single-point modulation wireless communication device exhibits fine stability and consistency, is convenient for production, and enables the production cost to be reduced.
