When MAG is achieved, the circle becomes a single point on the Smith chart and the equation for the radius of the constant-gain circle becomes undefined.

I'm good with the one I have and it seems like it should be fit for purpose.

fRor low gain amps you can look at Miller Microwave.

Do I have to suck it up and carve a model out of soap or is there some help.

Someone might want to forward this message to them.
