ABSTRACT:
A surface acoustic wave device includes at least four surface acoustic wave elements that are arranged to have an unbalanced-to-balanced conversion function. In a surface acoustic wave element on the balanced side, the phase between the input and output terminals is 180 degrees shifted so that the phase difference between the outputs on the balanced side becomes substantially 180 degrees.
