The growing interest in commercial RF applications and high-frequency engineering has triggered a scramble for fundamental design and analysis information, which until now has been largely scattered in the literature and often hard to find. This expertly compiled resource gives microwave engineers instant one-stop access to a vast range of essential source material in a single convenient volume. Over 100 classic papers provide definitive treatment of design, analysis, and applications of ferrite/powdered iron circuits, RF transformers, power splitters, power combiners and directional couplers, all organized for ready reference. Engineers quickly find proven techniques, design solutions, and core data for the full range of HF components - from toroidal-wound inductors, multielement transmission lines, and broadband balun transformers, to hybrid power dividers and directional channel-separation filters.
