ABSTRACT:
A resonator system and method are provided which includes/uses a tunable reference resonator, parts for tuning the reference resonator to a reference value via a controlled variable for the reference resonator, a tunable circuit resonator, and parts for tuning the circuit resonator which are designed such that the controlled variable for the reference resonator is used as a measure of the tuning of the circuit resonator, and wherein the reference resonator and/or the circuit resonator is/are designed as a surface acoustic wave component, a bulk acoustic wave component and/or a diaphragm oscillator.
