ABSTRACT

 In this paper, a set of wireless FM transmitter system is designed. When the audio signal with peak value of 200mV and frequency of 2KHz is input, the transmission signal with resonant frequency of about 46Mhz and power amplification of 40-50 will be obtained. After scheme comparison, the wireless FM transmitter with VCO as frequency modulation device and AB high-frequency power amplifier as high-frequency power amplifier is finally determined, the designed circuit is verified by simulation software.
