Surface Acoustic Wave Filters

Surface Acoustic Wave Filters 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.
