Abstract: A filter includes an electromagnetic (EM) resonator having a first EM resonator terminal and a second EM resonator terminal. The second EM filter terminal is coupled to a ground terminal. The filter includes a first bulk acoustic wave (BAW) resonator coupled between the first EM resonator terminal and the ground terminal and includes a second BAW resonator coupled between the first EM resonator terminal and the ground terminal. A third BAW resonator is coupled between a first filter terminal and a first BAW resonator terminal of the first BAW resonator. A fourth BAW resonator is coupled between a second filter terminal and a second BAW resonator terminal of the second BAW resonator.

Abstract: In one example, an integrated circuit comprises a filter having first and second filter terminals. The filter includes a first inductor coupled between the first and second filter terminals. The filter further includes a resonator coupled between the first and second filter terminals. A second inductor is coupled between differential terminals and is magnetically coupled to the first inductor.
