Here is a very easy DIY FM receiver circuit diagram.
It is easy to build FM receiver circuit as the TA2003 IC used here, comes in easy DIP package.
It’s both Am and FM receiver IC, we’ll use FM, so FM circuit is only given. All the parts name is given in the diagram, click for a better view.
The L1, L2 and L3 coils are to made by hand. Take a 5mm diameter ferrite core, or other thing, to roll 22SWG copper wire to make those coils. Use a general purpose 500pF gang for tuning.
- L1=4T, 22SWG, 5mm dia
- L2=3T,22SWG, 5mm dia
- L3=3T,22SWG, 5mm dia
Make the connections of the GANG, coils as short as possible. The audio output should be fed to any amplifier for amplified sound output.
The main advantage of this circuit is that it requires much less current, and operates at 3V.
It could be used to check DIY FM transmitter circuits easily. Leave your comments below, your feedback is important.
Can u please send the website in India where I can buy TA2003 ic
Only available in Alibaba. com , china !!
OK then someone replied its just 30 Rs in India thats why I asked
Hi, thank you for this small voltage device, please is there any kind of FM circuit which does not have that white noise, cos i want to make a kind of microphone transmitter receiver circuit.
Thanks for your time.
Use this for the transmitter, https://www.circuitsdiy.com/the-simplest-tv-transmitter-ever-made/ .
You need to lower the frequency to use in FM band, 88-108 MHz. It's one of the best white noise less transmitter I've ever used.
Thank you very much, do you also have a receiver circuit?
There is an error in the scheme, I put it on the board and the only thing I got was static, after doing a good research on the data sheet. I realized that pin 14 of the IC should go to Vcc to run FM, if it's still pin 14 free, it's AM, I think for eeo on the radio station of an AM station, just that note, today I'll build the circuit again with that pin to vcc
Did you use the circuit connected to pin 10 in place of the two-pin ceramic filter other like to use. This has been confusing me. I have been looking for replacement circuit for the ceramic filter and bumped to this.
My circuit is not producing audio. Plz help me.
