SAW devices and their wireless communications applications - IEEE Microwave Magazine

65 ISSN 1527-3342/02/$17.00©2002 IEEE IEEE magazine Today’s second-generation (2G) wireless communications market is very dynamic with high growth rates. Soon, third-generation (3G) systems will start operation. Moreover, wireless local-area network (LAN) systems, such as Bluetooth or IEEE 802.11-based systems, are emerging. The key components in the microwave portion [both in the radio(RF) and...

Simulation Modeling and Optimization Technique For Balanced Surface Acoustic Wave Filters

An optimum design technique for balanced surface acoustic wave (SAW) filters is proposed. First of all, in order to evaluate the performance of balanced SAW filters by the computer simulation, a numerical model of balanced SAW filters is derived by using mixed-mode scattering parameters. Then the structural design of balanced SAW filters is formulated as a function optimization problem that aim...

COMSOL for Modelling of STW Devices

Electroacoustic resonators employing surface acoustic waves (SAW) are commercially widely used in RF filters, low noise frequency sources as well as various sensors. In all of these applications the resonance quality factor appears to be a limiting performance factor. Quite often practical Q factors are not limited by the materials, but by design deficiencies, enabling energy loss outside the r...

Surface Acoustic Wave Devices for Wireless Strain Measurement

Strain monitoring is a nondestructive inspection method that can reveal the redistribution of internal forces, or the presence of anomalous loadings, in structures. Surface acoustic wave (SAW) devices are small, robust, inexpensive solid-state components in which a wave propagates along the surface of a piezoelectric material, and such devices are used in large numbers commercially as delay dev...
