Abstract
A BAW device comprises a first BAW resonator () and a second BAW resonator (). The first BAW resonator and the second BAW resonator each comprise a first electrode (), a second electrode () and a piezoelectric layer () being arranged in each case between the first electrode and the second electrode of the associated BAW resonator. The first electrodes, the second electrodes and the piezoelectric layers of both BAW resonators are designed essentially identically. A first conductor track () extends from the first electrode of the second BAW resonator to a third electric element () of the BAW device and electrically connects said first electrode with said third electric element. A first dummy conductor track () extends from the first electrode of the first BAW resonator, is electrically connected to said first electrode and, apart from said first electrode, is not electrically connected to any further electric element. The first dummy conductor track is designed such that it influences the acoustic and capacitive properties of the first BAW resonator essentially in the same way as the first conductor track influences the acoustic and capacitive properties of the second BAW resonator.
