Finds documents with exactly this word group, in exactly this word order and spelling (e.g. "employer branding").
Finds documents with both search terms (e.g. sales AND bonus).
Finds documents with one or the other search term (e.g. porsche OR volkswagen).
Finds documents with all search terms. Blank space is understood as AND (e.g. man robot production).
Finds documents with no appearance of the word behind NOT (e.g. ford NOT "harrison ford").
Finds documents where the search term is mentioned at least "n" times."n" may be any number (e.g. COUNT(gear)>8).
Finds documents with both search terms in any word order, permitting "n" words as a maximum distance between them. Best choose between 15 and 30 (e.g. NEAR(recruit, professionals, 20)).
Finds documents with the search term in word versions or composites. The asterisk * marks whether you wish them BEFORE, BEHIND, or BEFORE and BEHIND the search term (e.g. lightweight*, *lightweight, *lightweight*).
Finds documents with the search term in different spellings. "?" allows only one character (e.g. organi?ation).
Special characters are understood as AND (e.g. Miller Bros. & Sons).

Abstract

The chapter delves into the growing demand for 5G technology driven by the increase in smart device usage and multimedia content downloads. It highlights the need for high-efficiency power amplifiers to support 5G's high data rates and low latency requirements. The text discusses the challenges posed by the high Peak to Average Power Ratio (PAPR) and the trade-offs between energy efficiency, quality of service, and spectral efficiency. It explores the design of novel power amplifier architectures, such as Doherty and switched cascode Class-E power amplifiers, to overcome these challenges. The chapter also presents the integration of these power amplifiers into a 4-phased-array transmitter topology, showcasing the potential for high-performance 5G systems. Throughout, the text emphasizes the advantages of deeply scaled CMOS technologies, such as 22nm FDSOI, in pushing the boundaries of existing state-of-the-art performance.
