摘要： The invention relates to a resonator operating with bulk acoustic waves (BAW resonator, BAW=Bulk Acoustic Wave) and band-pass filters constructed of such resonators. To increase the edge steepness of the transmission band of a BAW band-pass filter, the invention proposes reducing the effective coupling of a BAW resonator by using the connection in parallel of a BAW resonator and a capacitor instead of only one resonator. In addition, to increase the edge steepness of the transmission band, the use of a connection of coupled BAW resonators in the serial branch of a filter circuit with another resonator or resonator stack in the parallel branch of the filter circuit is proposed, the additional resonator or resonator stack being connected to the center electrode of the resonator stack specified initially.
摘要翻译：本发明涉及一种使用体声波（BAW谐振器，BAW =体声波）和由这种谐振器构成的带通滤波器的谐振器。为了增加BAW带通滤波器的传输频带的边缘陡度，本发明通过使用与BAW谐振器和电容器并联的连接而不是只有一个谐振器来降低BAW谐振器的有效耦合。此外，为了增加传输频带的边缘陡度，提出了在滤波器电路的并联支路中使用与滤波器电路的串行分支中的另一谐振器或谐振器堆叠的耦合的BAW谐振器的连接，附加谐振器或谐振器堆叠连接到最初指定的谐振器叠层的中心电极。

摘要： Overlapped electrodes of an electrical component are dimensioned in such a way that when there is translational displacement of one electrode in relation to the electrode situated opposite, their area of overlap remains within a manufacturing tolerance β/2, and also remains constant within the tolerance limits when there is a simultaneous rotation of the electrodes with respect to one another. This is achieved in that the intersecting edge pairs of the overlapping electrodes are designed parallel to one another, whereby the length, measured in the direction parallel to the respective edge pair, of the corresponding electrode everywhere exceeds by β the corresponding length of the area of overlap.
摘要翻译：电气部件的重叠电极的尺寸设计成使得当相对于位于相对的电极存在一个电极的平移位移时，它们的重叠面积保持在制造公差β/ 2内，并且在公差范围内保持恒定当电极相对于彼此同时旋转时。这样做的原因在于，重叠电极的相交边缘对被设计为彼此平行，由此在相应电极的平行于相应边缘对的方向上测量的长度在每个地方超过了相应的长度交叠。

摘要： An acoustic wave transducer includes an acoustic track having electrode fingers for different electrodes. The electrode fingers engage to form exciting finger pairs. The acoustic track also includes marginal areas and an excitation area. The electrode fingers engage in the excitation area. The marginal areas and the excitation area are located along a transverse direction of the acoustic wave transducer. A longitudinal phase speed of an acoustic wave in the acoustic track is less in a marginal area than in the excitation area, and the acoustic wave is excitable and has a transversal basic mode. The following applies in the transversal basic mode for a wave number ky: (ky)2>0 in a marginal area, and (ky)2

摘要： A directional coupler, comprising a first high-frequency line for feeding a first high-frequency signal, a second high-frequency line for feeding a second high-frequency signal, and a coupling line for outputting signals from the first and the second high-frequency lines, wherein the coupling line comprises resistive segments, each comprising a predetermined impedance. Coupling properties and resistive damping and adapting properties can be integrated in the coupling line. A compact and low-cost construction of the directional coupler is thus made possible.

摘要： The invention relates to a filter operating with bulk acoustic waves, comprising at least one first resonator and at least one second resonator. In the at least one first and second resonator, a longitudinal acoustic mode is capable of propagation, for which normal dispersion is adjusted in the first resonator and abnormal dispersion in the second resonator by selection of the material and the relative layer thicknesses. In particular, the power compatibility of the filter at the higher frequency edge of its passband can be improved.

摘要： A method for improving heat dissipation in an encapsulated electronic package usually referred to as a chip-size SAW package. The package comprises one or more acoustic-wave components fabricated on a die, which is disposed on an electrically non-conductive carrier separated by electrically conducting bumps. The top of the package is covered by a laminate and a hermetic seal layer. Heat dissipation can be improved by removing a part of the laminate and then depositing a layer of thermal conducting material on the package, and by providing one or more heat conducting paths through the carrier.
