Hi there,

I'm looking for a FM reciever cicuit, i wonder if anyone can recommend me some.

I understand that there are a lot of FM reciever IC like philips's TDA series. But i want it to be analog, constructing it using transistors.

Thanks in advance.

Hi,

There is a very simple FM receiver, called (super) regenerative which includes only one active device at its input and gives demodulated audio at its output, and includes an audio amplifier IC for speaker or headphone usage.

Here is a link for it: http://www.zen22142.zen.co.uk/Circui...fmreceiver.htm

And here is another unusual but a very good FM receiver if you feel up to it:

Its mixer includes a double balanced ring diode mixer (SBL1 from MiniCircuits) and this may seem an overkill in an FM receiver but this is one feature which makes this receiver unique.

And here is a practical preamplifier with a JFET you may connect in front of the regenerative FM receiver: http://www.wenzel.com/pdffiles/fmpreamp.pdf
