Abstract

Identification devices (ID-tags) for remote telemetry systems in the European ISM standards require the use of narrow-band solutions. SAW ID-tags are characterized by particularly good coding and correlation capabilities which is used in many filter applications. To solve the narrow-band problem of ISM-bands two principles for passive SAW ID-Tags were introduced, the Multiple Apodized Self-Correlating Delay Line (MASCoT) and the “On-Chip-Correlation” (OCC) device. The advantage of the devices is an “impulse-free” interrogation so that the used bandwidth does not extend the allowed bandwidth and the European ISM standard can be fulfilled. The design, simulation and experimental results were introduced and discussed
