Help me make a 88 - 108MHz broadcast FM stereo receiver

for what frequency ?

88 - 108MHz broadcast FM stereo ? or

a narrowband receiver for somewhere else ?

you answer determines what circuit designs I could suggest

cheers
Dave

thanks for the reply i am looking to build 88 - 108MHz broadcast FM stereo receiver

ok there's 2 approaches you could use....

separate IF IC and Decoder IC eg....

TEA5570 AM-FM RX IF followed by a TEA5580 Stereo PLL Decoder

or an all in one IC ....

TEA5711 complete AM-FM Stereo RX IC

look up any of those TEAxxxx chips in google and you will find the datasheets that have complete example circuits for you to follow :)

The TDA7088T is one of the simplest around. It is not very sophisticated but works surprisingly well and is used in a lot of low cost radios. There is a Chinese imitation as well (called the CD9088 I think).

Sorry, my mistake.
