A hybrid filter includes a module substrate having a major surface and a major surface that are opposite to each other, acoustic wave resonator elements disposed at the module substrate, inductors disposed at the module substrate, and a capacitor disposed at the module substrate. The pass band of the hybrid filter is wider than the resonance band width of the acoustic wave resonator elements. One of the acoustic wave resonator elements, the inductors, and the capacitor is a first circuit element, and the first circuit element is disposed at the major surface. Another of the acoustic wave resonator elements, the inductors, and the capacitor is a second circuit element, and the second circuit element is disposed at the major surface.

Hybrid filter, multiplexer, radio-frequency module, and communication device

A filter module includes a first ground terminal, a second ground terminal, a low pass filter, and a second inductor. The low pass filter includes a first inductor provided in an input/output path of signal, a first capacitor provided in a first path connecting a first node and the first ground terminal, and a second capacitor provided in a second path connecting a second node and the second ground terminal. The second inductor is connected in series to the second capacitor in a path connecting the second capacitor and the second ground terminal. The first path and the second path are not connected to each other by any path except the one between the first node and the second node.
