Symmetric dual mode surface acoustic wave filter having symmetric housing connections |
摘要 |
A DMS filter is proposed with first and second interdigital transducers as a signal input or output that are located between reflector structures, wherein at least one acoustic track has a middle transducer that is split into partial transducers symmetric with respect to the perpendicular to the direction of propagation. The DMS filter is connected in a symmetrical manner to a housing using connection pads or connection pins in order to produce an axis-symmetrical connection layout.
