Abstract :
The gain and the stability of composite amplifiers consisting of a core 2-port amplifier and a lossless reciprocal embedding network is studied theoretically with particular interest in the design of near-fmax amplifiers. Design equations for finding an optimal embedding network that gives the highest MAG (maximum available gain) under a given stability requirement are presented. How such an embedding network could be synthesized is briefly sketched.
