Surface Acoustic Wave Filters

Informationen zum Autor David P. Morgan received a Ph.D. degree in Electrical Engineering from London University, for work on radar pulse compression using Surface Acoustic Waves. Since then he has been involved in research and development in a wide variety of topics, mostly in SAW, working at Nippon Electric Company (Kawasaki) 1970-71, University of Edinburgh 1971-77 and Plessey Research Caswell (Northampton, UK) 1977-86, where he was Group Leader for Surface Acoustic Waves. He is now a Consultant in this area. Dr. Morgan is author of the well-known text 'Surface Wave Devices for Signal Processing', and has also published over 100 technical papers. His knowledge of the SAW area has led to his being invited to lecture on the subject in the U.S., Russia, Finland, Japan, China and Korea. He is a Life Senior Member of the IEEE. Klappentext Complete coverage of all the latest devices which are key to mobile phones! TVs and radar systems. Zusammenfassung Covers the theory of acoustic wave physics! the piezoelectric effect! electrostatics at a surface! effective permittivity! piezoelectric SAW excitation and reception and the SAW element factor. These are the main requirements for developing quasi-static theory! which gives a basis for the non-reflective transducers in transversal bandpass filters.

Klappentext

Complete coverage of all the latest devices which are key to mobile phones, TVs and radar systems.

Zusammenfassung
Covers the theory of acoustic wave physics, the piezoelectric effect, electrostatics at a surface, effective permittivity, piezoelectric SAW excitation and reception and the SAW element factor. These are the main requirements for developing quasi-static theory, which gives a basis for the non-reflective transducers in transversal bandpass filters.
