Surface acoustic wave filters : with applications to electronic communications and signal processing / David Morgan

Includes bibliographical references and index

Acoustic waves in elastic solids -- Electrical excitation at a plane surface -- Propagation effects and materials -- Non-reflective transducers -- Bandpass filtering using non-reflective transducers -- Correlators for pulse compression radar and communications -- Reflective gratings and transducers -- Unidirectional transducers and their application to bandpass filtering -- Waveguides and transversley coupled resonator filters -- Resonators and resonator filters -- Fourier transorms and linear filters -- Reciprocity -- Elemental charge density for regular electrodes -- P-matrix relations -- Electrical loading in an array of regular electrodes

"Now thoroughly updated since it was first published in 1985, this new edition gives the fundamental principles and device design techniques for surface acoustic wave filters. All the devices in widespread use today are covered: bandpass and pulse compression filters, correlators and non-linear convolvers and resonators. The newest technologies for low-loss bandpass filtering are given full treatment, including unidirectional transducers and the use of resonators in impedance element filters, longitudinally-coupled resonator filters and transversely-coupled resonator filters, the last making use of waveguiding effects."--Jacket
