Allowing for sidebands above the nominal 30 kHz IF, you will need an
A/D converter running at 100 kilosamples/second or more. This is
well within state-of-the-art for A/D converters, but it is
substantially faster than one usually sees in sampled-IF radios today
(i.e., it would require more A/D performance and more DSP horsepower
than designers normally use).
Do you intend to design your own sampled IF using an A/D or DSP eval
board (or your own board design), or were you looking for a
plug-and-play solution that someone has already developed?
Best regards,
