Hello,
I like to do build or buy an RF front end for an ADC to be able to capture RF signal and process with them.
Perfectly I like to cover the frequency range of FM and AM radios (150MHz).
The RF would have an antenna interface and a heterodyne stage. The ADC that I have can sample up to around 100 MSpS but I like that my sampling rate be around 20 to 30 MSpS so the heterodyne should down convert to 10MHz.
For AM radio receiving I think I don't need the heterodyne stage and I can sample at the rate of 1o MSpS.
And my question: Where should I start? Can I buy anything such as this? My budget isn't very high so I can't buy anything more than 100pound or so on.
Any help appreciated.
Best regards
Mansour
