  • Patent number: 10873352
    Abstract: A radio-frequency module (20) includes a module substrate (50) and a filter (21). The filter (21) has a sensitive GND electrode and a non-sensitive GND electrode that are connected to an external-connection ground terminal of the module substrate (50), and parallel-arm resonators. An inductance component generated by the sensitive GND electrode shifts, by a first shift amount, an attenuation pole that corresponds to a parallel-arm resonator and that is formed near a pass band. An inductance component generated by the non-sensitive GND electrode shifts, by a second shift amount, an attenuation pole that corresponds to a parallel-arm resonator and that is formed near the pass band. The first shift amount is larger than the second shift amount, and the distance between the sensitive GND electrode and the external-connection ground terminal is smaller than the distance between the non-sensitive GND electrode and the external-connection ground terminal.
