<p>The bulk acoustic wave (BAW) apparatus has two BAW resonators (72,74) connected in antiparallel, such that the resonators have same polarization direction. The top electrode (72T) of BAW resonator (72) is electrically connected to the bottom electrode (74B) of BAW resonator (74) and electrical terminal (76) of BAW apparatus. The bottom electrode (72B) of BAW resonator (72) is electrically connected to the top electrode (74T) of BAW resonator (74) and electrical terminal (78) of BAW apparatus. Independent claims are also included for the following: (1) method of reducing non-linear properties within BAW apparatus; and (2) BAW filter.</p> |
