Description
This book gives the fundamental principles and device design techniques for surface acoustic wave filters. It covers the devices in widespread
use today: bandpass and pulse compression filters, correlators and non-linear convolvers and resonators. The newest technologies for
low bandpass filters are fully covered such as unidirectional transducers, resonators in impedance element filters, resonators in double-mode
surface acoustic wave filters and transverse-coupled resonators using waveguides.
The book 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 and interdigital pulse compression filters. It is also needed for the reflective transducers used in
the newer devices.
