  • Bulk acoustic wave (BAW) filter with coupled inductors
    Patent number: 10263599
    Abstract: A Bulk Acoustic Wave (BAW) filter includes a series branch coupled between an input node and an output node. The series branch has multiple BAW resonators that are coupled in series, wherein a first series resonator is coupled between a first node and a second node in the series branch. A first shunt resonator is coupled between the first node and a fixed voltage node, such as ground, and a second shunt resonator is coupled between the second node and the fixed voltage node. Further, a first inductor is coupled between the first node and the fixed voltage node, and a second inductor is coupled between the second node and the fixed voltage node. The first inductor and the second inductor are magnetically coupled to one another to generate a virtual inductance between the first node and the second node and in parallel with the first series resonator.
