The aim of this book is to serve as a design reference for students and as an up-to-date reference for researchers. It also acts as an excellent introduction for newcomers to the field and offers established rf/microwave engineers a comprehensive refresher.  The content is roughly classified into two – the first two chapters provide the necessary fundamentals, while the last three chapters focus on design and applications. Chapter 2 covers detailed treatment of transmission lines. The Smith chart is utilized in this chapter as an important tool in the synthesis of matching networks for microwave amplifiers. Chapter 3 contains an exhaustive review of microstrip circuits, culled from various references. Chapter 4 offers practical design information on solid state amplifiers, while Chapter 5 contains topics on the design of modern planar filters, some of which were seldom published previously. A set of problems at the end of each chapter provides the readers with exercises which are compiled from actual university exam questions. An extensive list of references is available at the end of each chapter to enable readers to obtain further information on the topics covered.

This monograph reports a research carried out to design monolithic microwave integrated circuit (MMIC) low pass filters using circuit and electromagnetic simulations. The filters were designed to be constructed on both Si and GaAs semiconductor wafers. The principal objectives were to reduce both circuit size and spurious content. Three types of designs are proposed here. The first is a Butterworth filter made of commensurate stubs, while the second filter is of the m-derived type. Both filters are realized using a single gold layer on the semiconductor substrate. The third filter uses a novel metal/polyimide/metal multilayer structure consisting of buried coplanar waveguide and polyimide overlay. Owing to the unique multilayer architecture, the filter operates well without spurious in the passband and stopband. The combination of several different materials in the structure also reduces the size. The proposed filter has stopband insertion and return losses of 20 dB and 25 dB respectively. A theoretical model to explain the new structure and design methodology are discussed in detail.
