Simple Fm Radio Circuit Diagram. The heart of this circuit is a digital ic tda7000. When it comes to making an fm receiver it s always thought to be a complex design however the one transistor simple fm receiver circuit explained here simply shows that it isn t the case after all.
In some areas 3 stages of audio amplification may not be necessary in which case tr3 and its associated components can be omitted and the free end of capacitor c5 connected to the collector of tr2. It has an op amp internally which acts as an amplifier. Frequency can changed by adjusting of variable capacitor c3.
The fm radio circuit mainly consists of lm386 ic.
This simple fm radio receiver circuit consists of a regenerative rf stage tr1 followed by a two of three stage audio amplifier tr2 to tr4. Since the ic is dedicated to build radio circuits this circuit is very much reliable to an extent. This circuit is designed as per the. You should connect an audio amplifier with output of fm receiver for sufficient output that can listen do you want the audio output.
