John,
I'd like to offer an alternative idea-
Back in the 1990's Q-bit Corporation made a variety of compact broadband
amps for applications such as this. Many will happily run with a 0 dBm input
and provide 0.5 - 1w or more out. There are usually several models available
on eBay. Specs can still be found on the internet for some models. While
many are listed for +15 or +24 Vdc input they'll often run fine on less but
their gain will be lower.
73,

Subject: [Elecraft] Boots for the XG3...
A few days back I inquired of the list if anyone knew of a small
post-amp that would prefilter the XG3 square wave and give it about 30
dB boost. There were no answers. The problem seems to be that most QRP
or QRPp amps already require a few tenths of a watt input, and the 1 mW
from the XG3 is just too tiny...
