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 (http://www.wj.com/pdf/ECG003.pdf) 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,

Why would you need specs like that? You don't ordinary rely on an
amplifier to provide that kind of flatness. You need a detector and a
PIN modulator in a closed loop.
