Fm transmitter circuit Power supply :- Using power supply stable DC voltage 2 V to 3.7 V max. You can only use battery because battery is perfect for this circuit battery output doesn't any noise. Components :- Transistor BC 547 , Resistance 100 ohm , 4.7 K ohm . Capacitor 1nF, 47pF, 22pF. Inductor 1uH. Condenser mic any . Resistance :- Using resistance 100 ohm +-5% changing 1/3 watt, 4.7 K ohm +-5% changing 1/3 watt. Capacitor :- 1nF this capacitor number 102 non-polar, 22pF this capacitor number 22 non-polar, 47pF this capacitor number 47 non-polar. Inductor :- This part important part for any transmitter circuit, 1uH 5Turn 24SWG. Transistor :- BC 547 is an NPN Bipolar junction transistor. It is commonly used to amplify current. A small current at its base controls a larger current at collector & emitter terminals. It has a transition...
