They also conveniently forget to deal with all the bane of all wideband
SDRs – interfering signals in one band will, at best, decrease
in other bands. 80dB SNDR is nowhere near enough to simultaneously
receive, say, GPS data and process CDMA phone calls without something
a diplexer in the front end to split off the appropriate frequency
Any bets on what the chip effectively is? Just a bunch of relatively
high-speed 14 bit ADCs all phased appropriately? Or something fancier?
