Dr. David B. Rutledge (born January 12, 1952 in Savannah, Georgia) was elected Chair of the Division of Engineering and Applied Science at the California Institute of Technology (Caltech) and started his term on September 1, 2005 as such. His research group is currently involved in building circuits and antennas for numerous electronic applications. His work on microwave circuits has been important for various advances in wireless communications and has been useful for applications such as radar, remote sensing, and satellite broadcasting.
He joined the Caltech faculty as an assistant professor in 1980, and rose through the faculty ranks to become the holder of the Tomiyasu chair in 2001. He also served as executive officer for electrical engineering from 1999 to 2002. Rutledge is also director of Caltech's Lee Center for Advanced Networking, which aims at creating a global communication system that is as reliable and robust as a basic utility such as water and sewage.
Published works 
Professor Rutledge is the author of The Electronics of Radio, a book published by Cambridge University Press, as well as author or coauthor of numerous other publications. This book provides an introduction to analog electronics by analyzing the design and construction of a radio transceiver. Essential theoretical background is provided at each step, along with carefully designed laboratory and homework exercises. The goal of this approach is to ensure a good grasp of basic electronics as well as an excellent foundation in wireless communications systems. The book begins with a thorough description of basic electronic components and simple circuits. Next, the key elements of radio electronics, including filters, amplifiers, oscillators, mixers, and antennas are described. In the laboratory exercises, the reader is led through the design, construction, and testing of a popular radio transceiver (the NorCal 40A), thereby illustrating and reinforcing the theoretical material. This book, the first to deal with elementary electronics in the context of radio, is often used as a textbook for introductory analog electronics courses, or for more advanced undergraduate classes on radio frequency electronics. It may also be of interest to electronics hobbyists and radio enthusiasts.
