How to make FM radio easy at home
in this project we learn how to make FM Radio easy at home. here we use ta2003p ic using this ic you can easily build fm radio. you can complete this project using few simple steps and following circuit diagram.
Components for making fm radio:
- TA2003P IC
- 16 Pin IC Base
- 15pf Capacitor
- 471pf Capacitor
- 4.7uf, 25v Capacitor
- 220uf 25v Capacitor
- 2pin 10.7MHz Ceramic Filter
- 3pin 10.7MHz Ceramic Filter
- Variable Capacitor or Tuner
- 26Gauge 4 turn and 5 turn coil
- PCB Board
- 2n2222a NPN Transistor
- 1K Variable resistor
- ON/OFF Switch
- Soldering wire
- Soldering iron
in this project we use ta2003p ic its specially design for radio frequency.
TA2003P ic Radio Circuit Diagram:
- Ta2003p IC has 16 pin
Circuit Diagram of FM Radio using ta2003p ic
- Connect 1st pin with antenna. (you can use any copper wire as a antenna)
- 2 number pin use for 3v - Negative power supply.
- 6 number pin use for 3v + Positive power supply.
- Connect 3 pin 10.7 MHz Ceramic Filter with 3,6 and 8 number pin.
- And connect 2 pin 10.7 MHz Ceramic Filter with 10 number pin and 3v + positive power.
- Connect 471pf Capacitor with 11 number pin and 3v + positive power.
- Now connect 15pf capacitor with 13 number pin and 2nd side connect with 4 turn coil. and 2nd side of coil connect with 3v + positive power.
- Connect 14 number pin with 3v + power.
- Now connect 5 turn coil with 15 number pin and 3v + positive power.
- Connect + Positive side of 4.7uf capacitor with 11 number pin
Now make amplifier circuit:
- 2n2222a transistor has 3 pin. (1st emitter, 2nd base, 3rd collector)
- connect middle pin of 1k variable with base pin.
- connect speaker with collector and 3rd pin of variable resistor.
- Emitter Connect with 9 number pin of ta2003p ic.
- Positive side of 220uf capacitor connect with Negative side of 4.7uf capacitor
- Negative side of 220uf capacitor connect with 1st pin of 1k variable resistor.
Now make Tuner circuit:
Variable Capacitor or Tunner has 3 pin
- 1st pin connect with 15 number pin of ta2003p ic
- 2nd pin connect with 2 number pin of ta2003p ic
- 3rd pin connect with 15pf capacitor
