    摘要: 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.

    摘要: An electrical component is described with a first signal path (TX, RX1) and a second signal path (RX, RX2) that are connected to a common signal path (ANT, RX12). In the first signal path a first filter (F1) is arranged, and in the second signal path a second filter (F2) is arranged. The component comprises a first matching circuit (MA1) that comprises a shunt arm to ground. In the shunt arm, an inductor (L) is arranged, which is connected to the first signal path, the second signal path, and the common signal path. The component comprises a carrier substrate (SU) on which the filters (F1, F2), which are preferably implemented as chips, are mounted. The inductor (L) is integrated in the carrier substrate (SU).

    摘要: Between the two acoustic tracks of a SAW filter constructed on the surface of a piezoelectric substrate, a metallic shielding structure is positioned and connected to ground in order to shield two transducers positioned in different tracks. In this way crosstalk within a filter is prevented and the stop-band selection is improved.

    摘要: 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.

    摘要: A surface acoustic wave (SAW) filter includes a piezoelectric substrate, and acoustic tracks on the piezoelectric substrate. The acoustic tracks are adjacent and electrically interconnected. The acoustic tracks include electro-acoustic transducers. The electro-acoustic transducers include an input transducer and an output transducer. The SAW filter also includes a shielding structure that is metallic and that is connected to ground. The shielding structure is between the acoustic tracks. The shielding structure shields a first electro-acoustic transducer in a first acoustic track from a second electro-acoustic transducer in a second acoustic track.
