Abstract: Disclosed is an electric surface acoustic wave component comprising a multi-transducer arrangement and intersecting strip conductors (211, 221). Preferably, said component is a resonator filter having an acoustic track (100) that is defined by means of reflectors. In one variant, a transducer (112) is provided with a V-split. Partial transducers (112a, 112b) of said transducers are each conductively connected to another transducer (111, 113) of the same transducer arrangement. In another variant, four transducers (S1, S2, L1, L2) are interconnected in a bridge circuit. A first couple of transducers (S1, S2) are disposed in a first in-line transducer arrangement (100') while a second couple of transducers (L1, L2) are disposed in a second in-line transducer arrangement (200'). The couples of transducers are conductively interconnected by means of intersecting strip conductors (211, 221).

Abstract: The surface acoustic wave element comprises an electrically conducting component which form an acoustic groove and the finger electrodes (FE) are broadest in the base at the cross section at the base and taper themselves upward with increasing distance from the substrate top side. A dielectric layer of a relative layer thickness from 5 to 40% of the wavelength of the acoustic wave produced in the construction unit is arranged over the finger electrodes and piezoelectric substrate (PS). An independent claim is also included for a method of manufacturing surface acoustic wave element.

Abstract: 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

Abstract: The arrangement has a piezoelectric substrate, first and second surface wave structures (St1,St2) arranged on the substrate in series in the direction of propagation of the surface waves and consisting of metal fingers with a first and second finger period (p). The finger period varies continuously in the transition region between the structures and is smaller in the transition region than in the adjacent structures.

Abstract: A duplexer includes an antenna terminal, a transmit filter, and a receive filter. The receive filter includes a first sub-filter that includes one or more resonators, and a second sub-filter including a double mode surface acoustic wave (DMS) filter. The second sub-filter is downstream of the first sub-filter relative to the antenna.

Abstract: An electrical component has electrically conducting structures placed on an electrically isolating or semiconductive substrate and component structures sensitive to a voltage or an electrical arcing and galvanically separated from one another. To prevent an arcing between the galvanically separated component structures, the component structures are short-circuited with a shunt line having a smaller cross-section than the remaining electrical conductor tracks. The shunt lines can be burnt through by application of an electrical current at any given time, whereby a galvanic separation of the component structures is effected, if necessary, for the function of the component.

Abstract: An electrical circuit has at least two parallel signal paths connected to one another on the antenna side and for which a band reject filter corresponding to the transmission range is implemented in a second signal path for frequency-selective improvement of insertion loss in the transmission range of a first signal path. With a band reject filter, the signal is reflected to the junction of the parallel signal paths arising from the second signal path and thus is rerouted to the first signal path.
