  • Transducer for SAW arrangements
    Patent number: 4736172
    Abstract: In a directional transducer for SAW filters on a piezoelectric substrate, the transducer is formed of a plurality of groups which are connected in half-groups to busbars for two phases. The half-groups are alternately distributed into two or more channels such that the finger electrodes of each phase form a more or less gap-free series as viewed over all channels. A common, meandering busbar for both phases is associated with each channel.
