Fm Transmitter Circuit. This stage is served by q1 bc108. 100nf ceramic capacitor x1.
The following components are required to build this fm transmitter project. With the help of such fm transmitters we can easily transmit the audio signals through the carrier waves with different frequencies. However crystals controlled fm transmitter offers a crystal oscillator and frequency multiplier to develop a highly stable carrier signal frequency of 96mhz with 40 mw of rf output.
2n2222 npn transistor x2.
This fm transmitter circuit uses four radio frequency stages. Condenser mic audio jack or any other audio input part. 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. A vhf oscillator built around transistor bf494 t1 a preamplifier built around transistor bf200 t2 a driver built around transistor 2n2219 t3 and a power amplifier built around transistor 2n3866 t4.
