AVR-Chat

This may be the wrong place to ask, but it's at least related to the last "chat" :-)

I need to make an hi sensitivity/selectivity/stability, low noise tunable RF receiver that can receive around 60MHz (maybe 50-70) and ideally could switch to 10MHz (but the 10MHz requirements are not so stringent).
Worst case, I could separate the 10MHz receiver.

This would be somewhat similar to the requirements of an NMR receiver, if it helps.

Ideally I'd like something that has some first amplifier(s) then some IF stage(s) and then ... I will need IQ demodulation, but that could happen outside of this first chip (I'll also need to digitize the outputs, etc).

Any pointers, please?

Thanks,

Cat
