Who makes the best highly linear RF amplfier that meets this spec?

Data sheets are designed as lies. The always quote specs in such a way as to give a misleading impression as to what the device can do.

Its always this accuracy, that bandwidth at there power, but none of it is simultaneous.

In this case, the small signal bandwidths plots out to 100 Mhz are pretty much useless.

As a matter of course, all data sheets need to be inspected very closely to beat the marketing obfuscations. In fact INL and DNL were invented for that purpose. If a "16 bit" converter was actually truly 16 bit, only one spec on its accuracy would be required.

This is of course true for the first page of any data sheet these days.

For the rest of the pages, you have to be the Devil's advocate to find out if the parameters used relevant to you.

In audio business, companies promote ADC/DACs at 48/96/192 kHz sampling rate, but always measure SNR at 3 Hz to 20 kHz :-).

And as a real-world example, consider gigabit Ethernet: the baud rate is in the 100s meg range, not much beyond 100 meg Ethernet (that is, within an octave or two, but not a decade). The number of levels, on multiple duplexed pairs, is what pushes it out there. Besides active compensation and I don't know what else. Sure, you can do raw binary LVDS (or similar) well into the gigs, but it's not very useful beyond short onboard communications.

Well, in the audio business, that's what's really of interest. Anyone doing 192kHz digital audio is playing the same game. ;-)

FPDLink-III does 3Gb over 10m of cable.

No argument. 16 bits at 10 MHz (Msamp/s) is hard, going faster gets really hard.

Having glances at the arithmetic, i will take your word on that.

I may have to think this through a few times, but looks right.
