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 intricacies of phased-array transmitter design, beginning with the conventional direct conversion transmitter architecture. It explores the key components such as the local oscillator, I/Q modulator, power amplifier, band-pass filter, and antenna. The text then focuses on the phased-array architecture, which combines output power from multiple devices to achieve efficient high-power generation. The proposed 28 GHz phased-array transmitter for 5G is detailed, including the design of the polyphase filter, phase rotator, mixer, tunable low-pass filter, and power divider. The chapter also presents simulation and measurement results, demonstrating the performance of the designed components. This comprehensive analysis offers valuable insights into the optimization and trade-offs involved in designing high-frequency communication systems.
