FM receiver circuit

[Sukhbinder]

Hi guys, i'm looking for a FM receiver circuit for use with cordless microphones. any normal Fm receiver serves the purpose well but i need a dedicated receiver for my FM Mic. could any suggest any circuit with minimal components ( at least the indictors should be the least as they are the most difficult to make or find) if u can find something that uses DIP ICs then its better as i want to avoid using SMD components. the power supply requirements must be as low as possible (about 3V but can be taken up tp 9V). need it as quick as possible.
thanx

The circuit is only part of an FM radio.
I remember seeing those old ICs about 30 years ago. They aren't made anymore.

Hi to all, hey mvs sarma i asked for a FM receiver circuit and not a FM transmitter. you are right audio guru these ics went out long ago. any ideas about ics using FFL system for tuning. i found a few like CXA1191,KA22429,TDA7000 and TDA7088. any suggestions which will be the better choice. ???

Hi Sukhbinder,
The CXA1191 is the only "real" radio IC in your selection. My clock radio has an IC like it and it picks up local stations well. Even though the stations are strong, it doesn't overload.
The other ICs are garbage.

Thanks for you help audioguru. i happened to have a chinese made FM mic with receiver and found the receiver using the CXA1191. the mic is copy of the FM mic made by philips. i'll check out if the CXA1191 is available easily or not
