examining microwave circuit parameters such as scattering, ABCD, impedance, admittance, and image. A valuable feature of this chapter is a conversion table between the various circuit matrices characterizing two-port networks terminated in arbitrary impedances. The correct conversion has also never been treated in previous works. Next, the author sets forth a thorough treatment of asymmetric passive component design, which covers the basic and indispensable elements for integration with other active or passive devices, including: Asymmetric ring hybrids Asymmetric branch-line hybrids Asymmetric three-port power dividers and N-way power dividers Asymmetric ring hybrid phase shifters and attenuators Asymmetric ring filters and asymmetric impedance transformers With its focus on the principles of circuit element design, this is a must- have graduate-level textbook for students in microwave engineering, as well as a reference for design engineers who want to learn the new and powerful designmethod for asymmetric passive components.
