I have an application that must operate in the 25MHz to 40MHz region, with a channel having a nominal bandwidth of 50Khz to 700KHz or so. The Rx center frequency may be anywhere in the 25MHz to 40MHz region.
My question is about dynamic range requirements when operating a receiver in that neighbourhood of the spectrum. It's not a neighbourhood I've habitually "hung out" in, so I don't have any intuitive feel for how crowded it is, with emphasis on the Rx being in "deep rural" locations. My suspicion is that things like GSM receivers have a much worse time of it, and do OK with 14 bits of A/D. Is it likely that I'll need to do narrower analog filtering in the RF front end, to avoid dynamic range issues? It's more convenient if I don't have to do that, but specific Rx locations could have analog filters installed to more closely match their specific Rx frequencies.
