So where do we request free samples from :P The question is how would you get this into a computer? If we round it up to 16 bits, it makes 4.6 Gigabytes per second. Would a FPGA even be able to keep up? Could people a lot smarter then me, discuss how this chip could even possibly be used? Tim Ans

I think the chart is misformatted, this seems to make more sense Parameter GaAsSiGe Maximum clock frequency > 5 GHz > 15 GHz SINAD (signal to noise+distortion) > 70 dB > 110 dB Eff. resolution bits at 2.5 GHz carrier:

The punchline is towards the end of this article: http://rfdesign.com/mag/radio_new_technology_facilitates TechnoConcepts' RF to digital converter is the first 5 GHz carrier speed RF to digital converter capable of direct conversion of a 5 GHz RF carrier, eliminating all analog IF circuits.
