Hi All I have a Tv tuner that outputs 38.9 mhz If signal. I want to connect FM demodulator in front of it to receive Fm broadcast signals (88-108Mhz) as well as other transmissions. I have seen over the web at http://hem.passagen.se/communication/pic/uv916tr.gif fm demodulator but the demodulator IC MC13136 requires many external components as it converts the signal into 10.7mhz If. so as other ICs like FM radio receivers TDA7000 and LA1800. Can any one tell me how to demodulate 38.9Mhz signal without conversion. Is there any IC that can extract audio without converting it to 10.7Mhz.
