A book for engineers who design and build filters of all types, including lumped element, coaxial, helical, dielectric resonator, stripline and microstrip types. A thorough review of classic and modern filter design techniques, containing extensive practical design information of passband characteristics, topologies and transformations, component effects and matching. An excellent text for the design and construction of microstrip filters.
Over the last several decades, modern filter theory has been significantly embellished by many contributors. In Zverev’s [l] words “This search for useful theories has led to some of the most elegant mathematics to be found in the practical arts.” Excitement over this elegance is tainted by sophistication more suited for the filter mathematician than the engineer whose work is often less specialized. This book is directed to the engineer and not the mathematician. We do so in full reverence of the mathematicians who provided the tools to work with in the trenches.
For completeness, a review of which predates WW II. more recent and some is of classic material is included, some Of course most of the material is 1original. It is at times a strange mixture, but always directed at the practical application of the art to today’s real-world problems.
