Hi,

I'm trying to demodulate a 60kHz signal multiplied by a 5MHz carrier (amplitude modulation). I looked for ICs that could do this at such low frequencies but could only find a few surface mount ICs or ~$500 evaluation boards. Does anyone know a simple solution?

Thanks!

 

Did you try Minicircuits?

 

That looks interesting. So if I used this I would need a 5 MHZ oscillator and a LPF?

That should work. Many simple SSB demodulators use these. Minicircuits has lots of different models, in various packages.

 

Great, thanks for your help!

 

NIST time code?
