Reflectionless Filters Textbook Published

A new textbook titled Reflectionless Filters by NRAO scientist/research engineer Matthew A. Morgan has recently been published by Artech House.

This practical resource introduces progressive techniques in the creation of sophisticated reflectionless filter topologies — filter topologies that have identically zero reflection coefficient at all frequencies. Practical implementations are discussed along with their advantages when compared to classical absorptive filters, and their benefits in real-world systems such as up/down converters, multiplier chains, broadband amplifiers, analog-to-digital converters, and time-domain applications. Read more…
