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 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.

摘要： The invention relates to a micro-acoustic filter having a first and a second converter, in which the electromagnetic and capacitive cross-talk between the first and second converters is compensated for by providing additional coupling capacitors and additional current loops. Additional coupling capacitors and current loops are arranged in such a manner that they can counteract the sign of the natural coupling specified by the design and thus completely compensate for said coupling.

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, e.g., a diplexer or a duplexer, can have one of a number of diverse arrangements for terminal surfaces on the substrate bottom. For example, the terminal surfaces for first and second filters are not disposed at the maximum distance from one another. First and second filters can be disposed as one or two discrete components on the substrate, wherein one filter can be implemented as being integrated in a multilayer substrate.
