Abstract: A circuit is proposed by means of which a ceramic component having two electrodes can be provided with a uniform, but periodically alternating BIAS voltage. The component has properties dependent on the level of the BIAS voltage and, for the purpose of an increased service life, is connected to a generator for generating a BIAS voltage and to means for periodically reversing the polarity of the BIAS voltage present at the electrodes. In a method for operating the component having variable properties, a uniform BIAS voltage, the polarity of which is periodically reversed, however, is applied to the electrodes, and the service life of the component is thus increased.

Abstract: An electroacoustic transducer has reduced loss due to acoustic waves emitted in the transverse direction. For this purpose, a transducer comprises a central excitation area, inner edge areas flanking the central excitation area, outer edge areas flanking the inner edge areas, and areas of the busbar flanking the outer edge areas. The longitudinal speed of the areas can be set so that the excitation profile of a piston mode is obtained.

Abstract: A method of manufacturing a filter circuit including series and parallel coupled BAW resonators is given which compensates for frequency tolerances of the resonators which are due to the manufacturing process. The new method includes measuring a resonance frequency of at least one type of the BAW resonators produced on a wafer and defining a deviation from a desired frequency. A trimming layer is then deposited onto the entire wafer. At last, a thickness portion of the trimming layer is selectively removed, the portion being dependent on a location on the wafer and on the calculated deviation of the resonance frequency at this location.

Abstract: A bulk acoustic wave resonator includes an acoustically active area where an acoustic wave is excitable, and a transition area adjacent to an outside edge of the acoustically active area. A critical frequency of the acoustic wave in the transition area differs from a critical frequency of the acoustic wave in the active area. The transition area includes an additional layer. The bulk acoustic wave resonator includes electrodes for electrically connecting to electrical supply lines. The additional layer is irregular in areas adjacent to junction areas between the electrical supply lines and the resonator.
