ELASTIC WAVE ELEMENT, DEMULTIPLEXER AND COMMUNICATION MODULE |
摘要 |
An acoustic wave elementof the present invention has a piezoelectric substrate 30 and an acoustic wave resonator S1 on a main surface of the piezoelectric substrate 30. The acoustic wave resonator S1 is one being divided into a first IDT electrode55 and a second IDT electrode56 which are electrically connected to the first IDT electrode 55. The first IDT electrode55 includes a first comb-shaped electrode25 on the signal input side and a second comb-shaped electrode26 on the signal output side. The second IDT electrode56 includes a third comb-shaped electrode27 on the signal input side and a fourth comb-shaped electrode28 on the signal output side. The direction of arrangement of the third comb-shaped electrode27 and the fourth comb-shaped electrode28 from the third comb-shaped electrode 27 toward the fourth comb-shaped electrode28 is different from the direction of arrangement from the first comb-shaped electrode 25 toward the second comb-shaped electrode 26. |
