This book presents the application of microwave literature for designing lumped/semi-lumped filters and combline/iris-coupled microwave cavity filters. It provides the physical understanding of the terms and characteristics of radio frequency (RF) filters. The book complements engineering text books on RF components and provides support for the project assignments of students. In addition to the functional design of RF filters, the integrated design approach for produceability and reliability is explained.
