Abstract
Official abstract text for this publication.
An elastic wave includes a piezoelectric substrate having a polarization direction denoted by an arrow Px, and first and second IDT electrodes arranged on the substrate in an elastic wave propagation direction with a shared reflector therebetween. A first bus bar of the first IDT electrode and a first end portion bus bar of a second reflector are connected to a wiring electrode to define a first terminal. A second bus bar of the first IDT electrode and a second end portion bus bar of the shared reflector are connected to each other to define a second terminal. A first end portion bus bar and a first bus bar are electrically connected to each other. A second bus bar and a second end portion bus bar are electrically connected to each other, and the first and second IDT electrodes and are connected in parallel between the first and second terminals.
First claim
Opening claim text (preview).
What is claimed is: 1 . An elastic wave resonator comprising: a first terminal; a second terminal; a piezoelectric substrate having a polarization direction; first and second IDT electrodes extending in an elastic wave propagation direction on the piezoelectric substrate; a shared reflector located between the first IDT electrode and the second IDT electrode; a first reflector located opposite to the shared reflector with the first IDT electrode therebetween; and a s…
