摘要：
Although RF power amplifiers appeared immediately after the invention of the triode tube, and they felt an enormous advancement in the early 1930’s, they are still one of the most involved electronic circuits to design, as can be seen by the number of publications they still receive every year. So, as its title indicates, this talk addresses The Challenge of Designing a Power Amplifier, which every RF engineer has to face, and that includes, a plethora of 100 years of scientific knowledge plus a lot of empirical knowledge accumulated after many hours in the laboratory. So, the talk starts by giving an Introduction, where an overview of RF/microwave power amplifier needs and applications (mostly in the wireless communications billion-market) will be given. The talk will then evolve to the actual PA Design Challenges, illustrated with a practical design of a load-modulation amplifier architecture. Finally, the talk will close with some Conclusions.
