This book examines differential-mode and balanced microwave filters by discussing several implementations of practical realizations of these passive components. This book is divided into five parts. Part 1 is an introductory chapter, where the fundamentals of balanced lines, circuits and networks are presented. Part 2 covers balanced transmission lines with common-mode noise suppression and discusses strategies for common-mode suppression in balanced lines, application of common-mode filters to enhance common-mode suppression in single-band and dual-band balanced bandpass filters.
