 Given that I mentioned both Pout and Noise Figure of the MAX2471 in
my original post, I am obviously aware of those device specifications.
 
  I was attempting to ascertain whether anyone on the list had
direct measurements, or other insight, into the close in residual
phase noise performance of these parts, as I could not find any
further specifications or internal circuit info in the associated
datasheet and application notes.
 
  I have absolutely no aspirations of reaching a wideband noise floor
of -178 dBc/Hz whilst using a device with 0 dBm output power and
a noise figure of 8 dB.  But I suspect I can do as well as, or better
than, the op-amp designs, over a wider input bandwidth.
 
 Yes, if I need more than 0 dBm of output power, there will need
to be another output buffer or gain stage in the design, hence the
phrase  "... as part of a reference distribution design ..."
 
  If you know of anything else with comparable reverse isolation, 
usable from at least 10-200 Mhz, in such a tiny package, that
costs a buck a channel, please let me know!
