摘要：

A SAW-based temperature sensor system is presented. Much effort was placed in the development of a high temperature resistive transponder compromising of both a SA W device and an antenna stable up to 400C for at least a few days. The system solution also includes a low-cost reader unit employing the FSCW principle operating in the ISM band from 2.4 GHz to 2.4835 GHz. Spare space on the SAW device has been employed to also implement an ID for identification purpose. Hence, this solution also allows for tagging of objects exposed to harsh environments.
