摘要

This paper presents the design and the experimental results of a Monolithic Microwave Integrated Circuit Power Am-plifier in which the transistor-stacking approach is used within the Doherty architecture in order to maximize the achievable performance. In particular, the Stacked cell is realized by dividing the common source transistor in two smaller devices leading to a very compact and symmetric...
