What’s state of the art that isn’t space rated?

[RR] Obviously lots of things like the WiFi chips in every device on the planet (not in space):^)))))

I assume wayyy more capable than this thing? The Xilinx Ultrascale+ RFSOC has 16x 2.5GSP ADCs or 8x at 5GSP with 14 bits, and that’s sorta old tech at 16nm. 

[RR] Just a matter of price/performance tradeoffs at this point … agreed!  That said, space hardening comes at a cost …
