Nano SAW Devices For Sensing Applications

Design of Global Saw Rfid Tag Devices

The Global SAW Tag [1] is projected to be a large-volume SAW device application. The modulation method and overall tag data structure are reviewed for a family of proposed RFID devices. Current implementations use a basic group structure that encodes 16 information bits using 4 reflectors chosen from 75 reflector slots. Several groups are placed in-line on a single acoustic track to achieve ID ...

Considerations on nonlinearity measurement with high signal-to-noise ratio for RF SAW/BAW devices SAW/BAW

Introduction of new communication standards makes specifications given to RF surface and bulk acoustic wave (SAW/BAW) devices tougher and tougher. For example, futher improvement of the device linearity is demanded without increasing the device size. Nevertheless, it is still unclear where and how the non-linearity occurs. For finding origin(s) of the very weak non-linearity, its measurement sy...

Frequency Domain Modeling of SAW Devices

New SAW sensors for integrated vehicle health monitoring of aerospace vehicles are being investigated. SAW technology is low cost, rugged, lightweight, and extremely low power. However, the lack of design tools for MEMS devices in general, and for Surface Acoustic Wave (SAW) devices specifically, has led to the development of tools that will enable integrated design, modeling, simulation, analy...

Acoustomigration and Copper Metallization for High Power SAW Devices

Surface acoustic wave (SAW) devices are widely used for telecommunication or information technology systems. Trends to higher input power, higher frequencies or smaller structure devices, selectivity and bandwidth and better temperature stability are currently observed resulting in high power density levels. Particularly, this fact addresses to the thin film metallization of a SAW device (Fig. ...
