Do you actually need to do baseband sampling? It might be cheaper to bandpass and downconvert the received signal with an analog network first.

- pjc50 10y agoYou need the phase information. Actually, that might be a better way of simplifying the information to be sampled - a set of phase comparators.
- jhallenworld 10y agoPhase information is preserved when down converting. But resolution certainly will depend on bandwidth. I read that ultrasound propagation delay is ~650 ns / mm... this is something like 500 KHz for 1 mm (using rise-time * bandwidth = .35 approximation).
