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.
