Bulk acoustic wave device with coupled resonators |
摘要 |
<p>A bulk acoustic wave device includes first and second resonators, which are acoustically coupled and electrically connected in parallel. The first and the second resonator each comprise a first electrode, a piezoelectric layer formed at least partially on the first electrode and a second electrode formed at least partially on the piezoelectric layer. A coupling layer is provided between the first resonator and the second resonator.</p> |
