“…1 показаны топология и амплитудно-частотная характеристика (АЧХ) самосогласованного кольцевого фильтра с ОМПО на центральную частоту f0 = 45 МГц с относительной полосой пропускания Δf/f0 = 1,87 % на срезе УХ/128° LiNbO3. Фильтр обеспечил ВП = 0,8 дБ, затухание в полосе задерживания около 30 дБ в тракте 75 Ом [6].…”

“…В топологии фильтра применено фазовое взвешивание (ФВ) с малыми потерями входного и выходного ВШП. В тракте 50 Ом фильтр показал ВП = 1,5 дБ, затухание в полосе задерживания более 55 дБ при отстройке ± 8,6 МГц от f0 [6]. Фильтр используется во входных каскадах мобильных приемопередатчиков диапазона 146-174 МГц.…”

Printed and bound in Great Britain by Biddles Ltd, Guildford and King's Lynn This book is printed on acid-free paper responsibly manufactured from sustainable forestry in which at least two trees are planted for each one used for paper production.xii PREFACE fabrication technologies can help realize high Q micromechanical filters for frequencies up to and beyond 10 MHz, and micromachined surface acoustic wave (SAW) filters filling the gap up to 2 GHz. Fabrication processes for all these devices and their relative advantages are taken up extensively in this book. In addition, a brief description of packaging approaches that may be extended for these devices is also included for the sake of comprehensiveness in coverage.We have endeavoured to present these topics so as to guide graduate students interested to do research in microfabrication techniques and their applications. It is therefore envisaged that parts of this books would form the curricula of electrical and mechanical engineering, applied physics or materials science departments. In addition, this would also serve as a reference book for practicing researchers in these areas for further widening the scope of their research.Materials for this book have been taken from an advanced level course offered at Pennsylvania State University recently on RF MEMS, and many short courses presented across the world. Valuable comments from the participants of these courses have helped in evolving the contents of this book and are greatly appreciated. In particular we also wish to thank many of our colleagues and students, Taeksoo Ji, Yanan Sha, Roopa Tellakula, Hargsoon Yoon, and Bei Zhu, at the Center for Electronic and Acoustic Materials and Devices for their contributions in preparing the manuscript for this book.We would like to thank Professors Vasundara V. Varadan and Richard McNitt for their support and encouragement. Our thanks are also due to our families, in particular Nisy John, for bearing with our preoccupation in preparing this manuscript. We are also indebted to various researchers for their valuable contributions cited in this book.We are also grateful to the publisher's staff for their support, encouragement and willingness to give prompt assistance during this book project.

“…Surface acoustic wave (SAW) devices are commonly applied in modern commercial communication systems like radio-frequency (RF) front-end modules in cell phones, sensor devices for the detection of pressure and temperature as well as for micro-fluidic applications [2][3][4][5][6][7]. Since a few years the interest for SAW biosensors, for example, for the detection of hepatitis B antibody, is rising due to the high sensitivity and fast response time of a few minutes [5,8].…”

Aluminum nitride (AlN) based high frequency surface acoustic wave (SAW) devices are produced by using a new CMOS compatible concept. Textured c‐axis oriented AlN films have been deposited on tungsten based embedded interdigital transducers (IDTs) by the reactive pulse DC‐sputter technique within the thermal budget of back end of line (BEOL) processes. Two SAW Rayleigh modes with different acoustic velocities were measured and identified by finite element method (FEM) simulation (Kaletta and Wenger, FEM Simulation of Rayleigh waves for CMOS compatible SAW devices based on AlN/SiO2/Si(100) (Elsevier Ultrasonics, available online 18 April 2013, ISSN 0041‐624X, 10.1016/j.ultras.2013.04.009) [1]). Electromagnetic crosstalk between in‐ and output IDTs via low resistive Silicon substrates is one of the most troublesome sources of integrated SAW devices. The impact of several device parameters like the acoustic aperture, the number of fingers and the delay line length on the electromagnetic crosstalk was studied and routes for optimizing SAW filter designs on low resistive Si(100) will be presented.
