Transmitter Circuit. Apply a voltage of 12v through a battery to the circuit. As you can see the rf transmitter circuit consists of the encoder ic and rf receiver circuit consists of the decoder ic.
Since the transmitter does not need a regulated 5v we have directly powered it with a 9v battery. 1 watt four stage fm transmitter this fm transmitter circuit uses four radio frequency stages. Initially connect the circuit as shown in the circuit diagram.
Apply a voltage of 12v through a battery to the circuit.
Fm transmission is done by the process of audio pre amplification modulation and then transmission. The transistor pre amplifies the audio signal and is applied to the rf transformer. Apply a voltage of 12v through a battery to the circuit. 10nf ceramic capacitor x1.
