A very simple FM IF MW radio receiver circuit can be designed using the LA1260 IC manufactured by Sanyo Semiconductor .
As you can see in this FM IF MW radio receiver circuit schematic the LA1260 ic can be used in AM FM radio receiver electronic projects .LA1260 has integrated in the package many functions and features that are needed for radio receiver applications .
A very simple FSK demodulator for the 2025 Hz and 2225 Hz can be designed using the LM565 which is a general purpose phase locked loops IC containing a stable, highly linear voltage controlled oscillator for low distortion FM demodulation, and a double balanced phase detector with good carrier suppression.
Using BA1404 can be designed a very simple and useful fm stereo modulator electronic project . This BA1404 fm stereo modulator device works in FM broadcast band ( 75- 108MHz) and require few external common components .
