This chapter presents high-efficiency power amplifiers (PAs) for wireless infrastructure. It starts by stating the importance of high efficiency and the historical evolution in base station PA concepts. It then introduces the current solution, the Doherty PA. After explaining the fundamentals of the Doherty PA, a novel implementation achieving more than 35% drain efficiency across a 6dB power back-off range and up to 20W peak power between 1.7 and 2.3GHz is given. Afterwards, a future PA concept, switch-mode outphasing PA, is introduced. Theory and implementation details of a class-E outphasing PA achieving more than 60% drain efficiency across a 6dB power back-off range and up to 19W peak power between 1800 and 2050MHz is explained. By the end of the chapter, an essential part of switch-mode PAs, high voltage (up to 10V) and high frequency (up to 4GHz) drivers are presented.

This book explores the conceptual framework of European employment law, focusing on understanding the law's construction of employment relationships. The book draws on extensive comparative research of the legal architecture of employment relations in national legal systems and EU law to analyse the traditional model of the contract of employment and the difficulties of using the traditional model to frame modern working relationships. The authors then present a new model of the foundations of employment relationships, based on the concept of a personal work nexus, and explore the potential of their model to shape the future development of employment law. Throughout the book, the authors analyse the interaction of domestic and EU employment law, and discuss the possibility of future legal harmonisation in the area. They conclude by exploring the potential for a common framework for European employment law, in the context of broader debates surrounding the harmonisation of European private law.
