with acoustic surface waves of working sensorresonator - saw - resonator - for use as frequenzbestimmende component of an oscillator in a sensorschaltung

摘要

The invention concerns a multi-mode surface wave resonator (11) to be used as a frequency-determining component of an oscillator in a sensor circuit, wherein the resonator (11) forms a sensor for magnitudes, for example, of a mechanical, electrical, magnetic, thermal or chemical nature.
