摘要： The invention relates to a transducer that works with surface acoustic waves in which interfering transversal modes are suppressed. This is accomplished by mutually adapting to one another the transversal excitation profile of the acoustic wave and the transversal basic mode of the waveguide formed by the acoustic spur and adjacent exterior areas. This adaptation is accomplished by dividing the acoustic spur into an excitation area and marginal areas, whereby the width of a marginal area is approximately one-quarter wavelength of the transversal basic mode, and whereby the wave number of the transversal basic mode in the excitation area is zero. In one advantageous further development of the invention, an excitation strength that is a function of the transversal coordinate can be attained that is optimally adapted to the basic mode by dividing the excitation area in the transversal direction into partial spurs that are wired to one another serially and/or in parallel.

摘要： 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.

摘要： 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.

摘要： 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.
