Instructor: Jurgen Machui, Siemens Matsushita Components
The objective of this course is to provide insight into SAW filter techniques used for the public mobile communication. Starting with the SAW transversal filter for high precision filtering in digital radio relay systems the tutorial will cover SAW components used for frequency control and will focus on SAW devices used in mobile and cordless phones. Emphasis will be put on the low-loss problem, its solutions and their practical aspects. Modeling simulation, design and performance of SAW devices, as well as their fabrication processes are reviewed. The discussion will also include the application aspects with their specific demands on SAW filters.
Jurgen Machui, was born in Hamburg, Germany, in 1954. He received the M. Sc. degree in fluid mechanics in 1980 from Bristol University, England, and the diploma in mathematics from the Technical University of Munich, Germany, in 1981. He received the degree of docteur en sciences physiques from the University Paris XI, Orsay. In 1982 he started to work on SAW technology at the Corporate Research and Development, Siemens AG, Munich. From 1985 to 1988 he was with Thomson-CSF, Central Research Laboratory, Orsay, France. J. Machui joined the Research and Development activities of Siemens Matsushita Components, Munich in 1989. Since July 1994 he has been responsible for the development of new SAW filter technologies.
