Simple Fm Transmitter Circuit. 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. The first stage is the preamplifier stage where an audio input signal is amplified before modulation.
Fm transmitter circuit requires an oscillator to generate the radio frequency carrier waves. This stage is served by q1 bc108. In the schematic you will see the components required for making an fm transmitter the transmission range of this circuit is approximately 10 20 meters.

This is how this simple fm transmitter circuit looks on breadboard the audio output signal from the microphone is usually small the first transistor thus performs the job of amplifying that signal to a level good enough for transmission. An fm transmitter circuit is a high frequency wireless device which is able to transmit voice signals into atmosphere so that it can be received by a corresponding fm receiver circuit for reproducing the voice signals in a loudspeaker. The schematic of fm transmitter is given below.
