Foreword

100 ADS Design Examples, based on the author's RF and Microwave Circuit Design textbook is a hands-on step-by-step RF and microwave circuit design examples for university students and a valuable resource for aspiring RF and Microwave engineers.

Professor Behagi's book is valuable in that it marries RF and Microwave theory with the practical examples using the Keysight's Advanced Design System (ADS) software.

ADS is one of today's most widely used Electronic Design Automation (EDA) software used by the world's leading companies to design ICs, RF Modules and boards in every smart phone, tablet, WiFi routers as well as Radar and satellite communication systems.

RF and Microwave design techniques and ADS are also getting widespread adoption for baseband, high-speed applications. Knowing the fundamentals and practical application of RF and Microwave design with ADS will broaden your potential career opportunities.

Read these books and you'll have an advantage over others. Master all the 100 examples and additional exercises will help you to write your own ticket to success.

100 ADS Design Examples

Preface

The 100 ADS Design Examples book is mainly written for practicing engineers and university students who know the basic theory of analog RF and microwave engineering and want to apply the theory to the analysis and design of RF and microwave circuits using the Keysight ADS software. The book is based on the RF and Microwave Circuit Design textbook written by the author and published in August 2015. The ADS design examples are divided into 8 chapters as follows: 1. RF and Microwave Components 2 . Transmission Line Component Design 3 . Network Parameters and the Smith Chart 4 . Resonant Circuits and Filter Design 5 . Power Transfer and Impedance Matching 6 . Distributed Impedance Matching 7 . Single Stage Amplifier Design 8 . Multi-Stage Amplifier Design

Each example has an associated ADS workspace that comes in separate package. University students and practicing engineers will find the book both as a potent learning tool and as a reference guide to quickly setup designs using the ADS software. The author also uses CAD techniques that may not be familiar to some engineers. This includes subjects such as the frequent use of the MATLAB scripting capability.
