To my wife Cho Soon-Duk ( )
and son Yeom Jae-Hyung ( )

This book primarily examines active microwave circuit design, an important part of microwave engineering. This subject has worldwide appeal given the incredible growth in mobile and satellite communications. In the past, the use of microwaves was limited to radars and weapon systems, and to remote sensing and relay systems. However, due to the rapid expansion of mobile and satellite communication systems in recent years, systems that use radio waves or microwaves can be found in almost every sphere of our lives. Thus, it is clear there is an increased need for educational materials about active microwave circuit designs. This text is intended as a guide for graduate students who have majored in electronic engineering and its related fields. It should also be useful to engineers and professionals working in these fields who want to update their knowledge through independent study.

In writing this guide, I make the assumption that readers have majored in electronics or related fields as undergraduate students. In particular, readers are assumed to have the prerequisite knowledge of circuit theory, electronic circuits, and electromagnetics, which are usually covered in mandatory courses at the undergraduate level.

Numerous books have been published on the subject of active microwave circuit design. However, many of these works do not present the hands-on approach required in modern curricula, making it difficult for readers who only have the basic prerequisite knowledge mentioned above, to understand and follow such texts. For these readers, practical design skills may be hard to acquire by simply reading a text that presents only theory based primarily on mathematical explanations. On the other hand, most people working in this field have become familiar with the prevalence of design software employed in active microwave circuit designs, such as the Advanced Design System (ADS) from Agilent Technologies and Advancing the Wireless Revolution (AWR) from AWR Corporation. The design environment for active microwave circuits has changed drastically with the continuous expansion of microwave applications into our daily lives. Recently, a variety of software design tools applicable to circuit design, system design, and electromagnetic analysis of passive structures has emerged. This has significantly reduced the need for analytical methods and specific design-oriented, in-house programs for the design of circuits and systems. With these advances, the rapid exchange of results between designers has facilitated independent study and experimentation with basic concepts using software tools and practical designs. Clearly, innovations in the field underscore the necessity for advanced education in active microwave circuit design and improvements to relevant software tools. The practical design skills for active microwave circuit designers can be effectively improved through hands-on practice with design software. More than ever, the importance of ongoing education to an engineer in this field cannot be overemphasized.

Given this perspective, it is my view that an education incorporating these features has become imperative. With more than 17 years of experience educating graduate students, I have written this guide to address the critical importance of this subject. With this book, readers will acquire
