@JKolstad71HatesSpam: "Could someone point me in the direction of how you might go about flattening 
the frequency response of a wideband amplifier MMIC?  I'm looking at something 
like the Watkin-Johnson ECG003 (<url> and noticing 
that the response drops a little over 2dB from 500MHz to 2.5GHz.  Assuming 
that I've got plenty of SNR, component count isn't a big deal, and I don't 
mind tweaking trimmers, how might I go about flattening that respone to, say, 
0.5dB or better across that range?  Or is it just not very practical?
Thanks,

Obscenely wideband (>500MHz) software-defined radios.  There are people out 
there asking for such things to be built  hence the question!  (And 
wondering whether or they're just having pipe dreams and technology just 
isn't there yet...)"

A lead-lag filter with the pole out beyond 2.5GHz may do it for you, but 
I have no idea how you'd actually implement it.
Ditto for cleverly placed stubs.
And don't call me when the next batch has slightly different 
characteristics, or when the one you have varies with temperature.
I recall someone writing about this in QEX quite a while back  it was 
his first time designing an IF for a radar, and it had to be WIDE band.

As far as I'm aware, pretty much all high data rate digital modulation 
schemes can be recovered with 6 bits (or less).
OK, 1.25Gsps? :-)  I'm just talking ballpark figures.
