Fm Transmitter Schematic. Typical fm transmitter design s usually follow the block diagram below. Usually personal fm transmitters are plugged into the audio device let s say an mp3 player and then the frequency for the broadcasting is selected.

The circuit functions quite like a colpitts oscillator incorporating a tank circuit for the generation of the required oscillations. Fm transmission is done by the process of audio pre amplification modulation and then transmission. Typical fm transmitter design s usually follow the block diagram below.
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.
Making an fm transmitter is one of the best electronic projects that newbies can try. 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. Fm transmitter with max2606. Generally the fm transmitter uses vhf radio frequencies of 87 5 to 108 0 mhz to transmit receive the fm signal.
