ABSTRACT:
A miniature thin film microwave frequency acoustic filter device comprising acoustic resonators formed on the same dielectric membrane so that their frequency responses are identical. Because the filters are miniature, they can be manifolded without manifolding circuitry that normally causes significant filter losses.
