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 duplexer is proposed with a substrate which has at least one patterned metallization plane and on which, at least to some extent, a transmission path (TX) and a reception path (RX) are arranged, both of which are connected to an antenna connection (ANT). The duplexer comprises a transmission filter (TXF) which is arranged in the transmission path (TX) and which has a first acoustic wave filter (BAW1) with one or more resonators. Furthermore, the duplexer (DPL) comprises a reception filter (RXF) which is arranged in the reception path (RX) on the antenna side and which has a second acoustic wave filter (BAW2) with one or more resonators and also a single-ended output. In addition, the duplexer comprises, in the reception path (RX), a balun (BL) which is connected downstream of the reception filter (RXF) and the output of which delivers a balanced signal and which is in the form of an LC circuit, wherein at least one inductance and/or at least one capacitance of the balun (BL) are implemented in the patterned metallization plane of the substrate.

摘要： An arrangement includes a substrate, a filter, a first bulk acoustic wave resonator, a second bulk acoustic wave resonator, and a large surface covering. The first bulk acoustic wave resonator includes a first electrode and a second electrode and is arranged flatly on the substrate. The second bulk acoustic wave resonator includes a first electrode and a second electrode and is arranged flatly on the substrate. The large-surface covering includes a metal layer over the substrate. The metal layer is connected to a ground terminal.
