Abstract: The invention relates to an SAW filter with improved selection or insulation. A metal protective structure is arranged between both acoustic tracks of an SAW filter which is embodied on the surface of a piezoelectric substrate in order to protect two converters which are arranged in different tracks and which are connected to the ground. As a result, crosstalk is prevented within the filter and blocking selection is improved.

Abstract: The invention relates to a stable electrical component comprising a carrier substrate (1) and a chip mounted thereon. The component comprises a reactance element and a support element which are at least partially disposed between the carrier substrate (1) and the chip (2). The reactance element is produced at least in part by at least one conductor track (31) and comprises at least one element selected from at least one coil, at least one capacitor and at least one transmission line. Said transmission line is a line that produces a phase shift of at least 30° at a bandpass frequency of the component.

Abstract: A substrate with an HF-compatible line arranged in this substrate will be proposed that is formed similar to a tri-plate strip line in which, however, at least one of the ground planes has a slot that follows the profile of the signal line arranged between two ground planes. With the aid of this slot, the capacitive constant of the line can be lowered and thus the impedance of the line can be increased.

Abstract: The module comprises a transmitter-path filter (F1) connected directly to an antenna terminal to which is also connected one terminal of an inductor, the other terminal being grounded. A receiver-path filter (F2) is connected to the antenna terminal via a capacitor (C), so that the inductor and capacitor together constitute an impedance matching circuit (MA). The capacitor and inductor may be formed as conductive areas on the multilayer substrate, e.g. of LTCC, on which the module is formed, and the filters may be of SAW or BAW type. Electrical element with a duplexer circuit consists of an antenna connection (ANT), which is connected leading with a transmission path (TX) and a receiving path (RX).

Abstract: A surface acoustic wave (SAW) filter having an improved edge steepness includes at least three resonators connected in series and/or parallel with one another. An edge steepness of a pass band is improved if a plurality of resonators with different finger periodicities of interdigital transducers are provided.

Abstract: Die vorliegende Erfindung betrifft eine Schaltungsanordnung (1) zur Anpassung der elektroakustischen Eigenschaften eines elektroakustischen Bauteils (8), die eine erste Leiterschleife (9) und ein weiteres Element (15) aufweist. Die erste Leiterschleife (9) weist eine Hauptschleife (16) und eine Gegenkopplungsschleife (17) auf. Die Gegenkopplungsschleife (17) hat einen Krümmungssinn, der entgegengesetzt zu einem Krümmungssinn der Hauptschleife (16) ist. Die Gegenkopplungsschleife (17) gleicht eine Kopplung (14) zwischen der Hauptschleife (16) und dem weiteren Element (15) aus.
