Opis

This book serves as a hands-on guide to RF tunable devices, circuits and subsystems. An innovative of modeling for tunable devices and networks is described, along with a new tuning algorithm, adaptive matching network control approach, and novel filter frequency automatic control loop. The author provides readers with the necessary background and methods for designing and developing tunable RF networks/circuits and tunable RF font-ends, with an emphasis on applications to cellular communications.

O autorze

Qizheng Gu graduated from Fudan University, Shanghai, China, and received his Doctoral Degree from Nihon University, Tokyo, Japan.

He was a visiting scientist and then a research scientist at MIT’s (Massachusetts Institute of Technology) Research Laboratory of Electronics from 1983 to 1993. Dr. Gu worked in industry with Pacific Science Communications, Inc. ("PCSI"), and then with Rockwell Semiconductor System, in San Diego, California since 1993. He joined San Diego R & D center, Nokia, Inc. in 1998 and was a Technology Fellow of RF System Architecture and Engineering there. He was with WiSpry, Inc., as a director of RF Systems Architecture before his retirement from work in 2013.

Dr. Gu has published three books and many journal articles. His previous book entitled ‘RF systems Design of Transceivers for Wireless Communications’ is published by the Springer Publisher in 2005. Other two books, “Microwave Integrated Circuit Design” and “Microwave Circuits Comprised of Dielectric Resonators” are in Chinese. He has granted and applied for more than eight patents in RF system architecture area.

·      Discusses the methods of characterizing, modeling, analyzing, and applying RF tunable devices and subsystems;

·      Explains the necessary methods of utilizing RF tunable devices and subsystems, rather than discussing the RF tunable devices themselves;

·      Presents and applies methods for MEMS tunable capacitors, which can be used for any RF tunable device;

·      Uses analytic methods wherever possible and provides numerous, closed-form solutions;

·      Includes innovative modeling techniques for tunable devices and networks, new tuning algorithm and adaptive matching network control approach, and novel filter frequency automatic control loop.
