ABSTRACT:
A surface acoustic wave filter arrangement is described herein. The surface acoustic wave filter arrangement includes a first gate configured to operate symmetrically or asymmetrically, and a second gate configured to operate symmetrically. The filter arrangement also includes a double-mode surface acoustic wave (DMS) filter structure including an input connected to the first gate, and an output. The output includes a terminal pair that includes two symmetrical terminals configured to operate symmetrically. Each of the two symmetrical terminals of the terminal pair is electrically connected at the output of the DMS filter structure to a cascaded resonator.
