  • Radio frequency module and communication device
    Patent number: 12113557
    Abstract: A radio frequency module includes: a first filter circuit disposed on a first path that connects an antenna terminal and a first input/output terminal, and having a passband that is a first frequency band; a second filter circuit disposed on a second path that connects the antenna terminal and a second input/output terminal, and having a passband that is a second frequency band higher than the first frequency band; and a band-elimination filter circuit disposed on the second path and having an attenuation band that is a partial band of a third frequency band that belongs to an unlicensed band ranging from 5 GHz or higher, and is higher than the second frequency band. The second filter circuit is an LC filter circuit that includes an inductor and a capacitor.
