Allison,
I know that in general MMICs (Mav, Ina, Era, Gali whatever) are eager of drawing current. If I understand Warren, he wants to change the first one or two 2n3904 in the chain just to clean the IMD. Then the one watt or more RF power transistor would be used.

Iz oos,
The big problem with MMICS is power...? The devices we are talking about eat 50-60ma each
and prefer to be run from a fixed voltage.? For a say 8V source that on the order of 400mW
each for receive or transmit.? Not friendly for battery powered systems.
The other price is layout has to be good or they will oscillate.
