Surface acoustic wave (SAW) devices are recognized for their versatility and efficiency in controlling and processing electrical signals. This has resulted in a multitude of device concepts for a wide range of signal processing functions, such as delay lines, filters, resonators, pulse compressors, convolvers, and many more. As SAW technology has found its way into mass market products such as TV receivers, pagers, keyless entry systems and cellular phones, the production volume has risen to millions of devices produced every day. At the other end of the scale, there are specialized high performance signal processing SAW devices for satellite communication and military applications, such as radar and electronic warfare. This volume, together with Volume 2, presents an overview of recent advances in SAW technology, systems and applications by some of the foremost researchers in this exciting field.

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. A thorough revision of a classic on surface acoustic wave filters first published in 1985 and still in print Uniquely combines easy-to-understand principles with practical design techniques for all the devices in widespread use today Complete coverage of all the latest devices which are key to mobile phones, TVs and radar systems Includes a new foreword by Sir Eric Albert Ash

When it is desired to measure the frequency of RF pulses to within a resolution comparable to the pulse spectral width, special techniques must be adopted. Double detection is such a method. The report presents a simplified mathematical model of the double detection frequency measurement technique. Both frequency and time domain (through the use of an FFT routine) responses of the two individual filters are considered along with the difference of the squares of the time domain responses. Good agreement between theory and experiment is shown. The model includes gating and thresholding and the effects of these parameters are investigated. A complete computer program description, listing, and test case are given. This model can be used to optimize the parameters of a double-detection system. Finally, the model has been used to evaluate the double detection performance of a variety of filter responses including Butterworth, flat exponential filter, brick wall, Kaiser truncated sinx/x, Hamming, and Gaussian.
