ABSTRACT:
The fingers of a multistrip coupler for surface acoustic waves are weighted in at least one, i.e., input or output, track so as to match a predetermined energy profile for that track. In one embodiment, the weighting is achieved by apodizing the fingers of the multistrip coupler. In another embodiment, each finger is formed in a variable-amplitude zig-zag pattern. The invention is particularly advantageous when used to transversely couple surface acoustic wave resonators.
