The present invention provides an interleaved IDT that is connected to and
overlaps adjacent IDTs. In particular, the interleaved IDT may be
connected to both an input IDT and an output IDT via corresponding bus
bars. The first bus bar of the interleaved IDT is connected to the bus
bar of the input IDT, and the other bus bar of the interleaved IDT is
connected to a bus bar of the output IDT. The interleaved IDT is coupled
electrically to the respective input and output ports of the overall
surface acoustic wave architecture. As such, the bus bars of the
respective input and output IDTs are effectively extended, such that the
adjacent edges of the respective input and output IDTs partially overlap
one another in an interdigitated fashion at the interleaved IDT.
