The FM transmitter circuit (Frequency modulation) is a circuit made up of a single transistor or a BJT. In a wireless communication, the (frequency modulation) FM carries the data or information by changing the frequency of the carrier wave as per the information or a message signal. Friends in this video I will show you FM Transmitter. How To Make A Long Range FM Transmitter. Friend it is a very simple circuit project and. The aim of this project is to develop a low cost long range FM Transmitter with audio modulation. The FM transmitter has 3 stages, A (VFO) Variable frequency Oscillator (30 mw), a class C driver stage (150 mw) and a class C final power amplifier (1 Watt). FM Transmitter Circuit Principle: FM transmission is done by the process of audio pre amplification, modulation and then transmission. Here we have adapted the same formula by first amplifying the audio signal, generating a carrier signal using an oscillating and then modulating the carrier signal with the amplified audio signal.
