Brian's amp should be pushing 18dB. If it isn't then he screwed up the
matching of the transistor input and output impedances. That's one
reason why I want to see his schematic.

Frank, wrong as usual. Here is an excerpt from
http://rfdesign.com/microwave_millim...fiers_improve/

"Consequently, the gain of a push-pull amplifier is the same as that of
an individual amplifier, where the output power is twice that of an
individual amplifier. Thus, push-pull amplifiers are frequently used
for combining power of individual amplifiers. However, there is more to
these amplifiers than combining power. This topology of amplifiers
helps cancel even harmonics and intermodulations and improves the
even-order intermodulation product."

Oh, let me guess... the man who wrote this article (director of
engineering at Mini-Circuits) doesn't know what he's talking about
either... LOL

Frank... you just keep getting better & better.
