Reflectionless Filters, Second Edition

Reflectionless Filters, Second Edition presents a class of filter topologies whose designs maintain a theoretically zero reflection coefficient at both ports across all frequencies. This resource for new circuit discovery explores how these configurations were arrived at and provides a toolkit to create absorptive filters to any specification.

Building upon a foundation of basic principles, practitioners discover what a reflectionless filter is, how it operates, methodologies for design and implementation, and how it improves the performance of real-world electronic systems. Work from classical filter topologies to transform even- and odd-mode analysis into a powerful synthesis framework for broadband, reflectionless design. Progress step-by-step through the synthesis of increasingly sophisticated reflectionless filter architectures, applying original techniques introduced in each chapter to discover and implement new designs. Develop practical solutions through worked examples, beginning with lumped-element circuits and extending to transmission-line implementations, all while preserving perfect input match. Apply the same principles to the design of reflectionless multiplexers, and translate these methods into real-world systems that require improved stability, performance, and efficiency.
