A new power/gain invariant is proposed as a high-frequency figure of merit for linear active 2-ports. Using this figure of merit, it is feasible to design amplifiers with potentially unstable devices which have power gains comparable in magnitude to Mason's U function and are optimum in the sense of maximising the 2-port added power.
