摘要： In a radio frequency module, the first inductor is disposed on the first principal surface of the mounting board and located on the first reception path through which a first reception signal of a first frequency passes, on an input side of the first low noise amplifier. The second inductor is disposed on the first principal surface of the mounting board and located on the second reception path through which a second reception signal of a second frequency lower than the first frequency passes, on an input side of the second low noise amplifier. The radio frequency component is disposed between the first inductor and the second inductor. A distance between the first inductor and the shielding layer is greater than a distance between the second inductor and the shielding layer. The first inductor overlaps the first low noise amplifier in a thickness direction of the mounting board.

摘要： A radio frequency circuit includes an amplifier capable of amplifying a first radio frequency signal and a second radio frequency signal that has a frequency different from a frequency of the first radio frequency signal. Here, the amplifier uses a first power-supply voltage to amplify one of the first radio frequency signal and the second radio frequency signal and uses a second power-supply voltage to amplify both the first radio frequency signal and the second radio frequency signal together. A value of the second power-supply voltage is greater than a value of the first power-supply voltage.

摘要： A radio-frequency module utilizing carrier aggregation includes a switch circuit that includes one input terminal and three or more output terminals and that simultaneously connects the input terminal and each of two or more output terminals selected from the output terminals, signal paths that propagate signals of corresponding frequency bands, band pass filters in the signal paths, and variable matching circuits in the signal paths. The circuit states of the variable matching circuits are changed in accordance with a combination of two or more signal paths simultaneously connected to the input terminal.

摘要： In a band pass filter, a first elastic wave resonator includes a first base board type and a first electrode configuration significantly improved or optimal for frequency characteristics of the first elastic wave resonator, and a second elastic wave resonator includes a second base board type and a second electrode configuration significantly improved or optimal for frequency characteristics of the second elastic wave resonator. A first attenuation pole provided by the first elastic wave resonator and a second attenuation pole provided by the second elastic wave resonator is steeper than if the first elastic wave resonator and the second elastic wave resonator that have different frequency characteristics include electrodes having the same configuration on the same types of base boards.

摘要： A radio-frequency module includes a first power amplifier, a second power amplifier, a switch, a plurality of first filters, and a second filter. The first power amplifier amplifies a transmission signal of a first frequency band and outputs the amplified transmission signal. The second power amplifier amplifies a transmission signal of a second frequency band and outputs the amplified transmission signal. The pass bands of the plurality of first filters are contained within the first frequency band. The pass band of the second filter is contained within the second frequency band. The second power amplifier has a greater output power level than the first power amplifier. The first output terminal of the first power amplifier is switchably connectable to the plurality of first filters via the switch. The second output terminal of the second power amplifier is connected to the second filter without the switch interposed therebetween.
