Abstract: A radio frequency module includes a first switch, a second switch, a control circuit, a first filter, a second filter, a third filter, a fourth filter, and an antenna terminal. The first switch is capable of connecting a first selection terminal or a second selection terminal to a first common terminal in a selective manner. The second switch is capable of connecting a third selection terminal or a fourth selection terminal to a second common terminal in a selective manner. The first switch, the second switch, and the control circuit are provided in a single electronic component (a first electronic component). The control circuit is positioned between the first switch and the second switch in the electronic component.

Abstract: In a radio-frequency module, a hybrid filter includes an acoustic wave filter including at least one acoustic wave resonator, an inductor having a winding portion, and a capacitor. A plurality of outer electrodes of the acoustic wave filter includes a first input and output electrode connected to a first signal terminal, a second input and output electrode connected to a second signal terminal, and a ground electrode connected to a ground terminal. The inductor is disposed on a first major surface of a mounting substrate and is adjacent to the acoustic wave filter in plan view in a thickness direction of the mounting substrate. When viewed in a direction of a winding axis of the winding portion of the inductor, an inner part of the winding portion in the inductor does not overlap any of the first input and output electrode, the second input and output electrode, and ground electrode.

Abstract: A transmission filter in a high frequency module includes serial arm resonators electrically connected in series to a serial arm electrically connecting a shared terminal and a transmission terminal, parallel arm resonators each electrically connected in series to each of parallel arms electrically connecting the serial arm and a ground, a first inductor electrically connected between the ground and a connection end electrically connecting at least the two parallel arm resonators of the parallel arm resonators, and a second inductor electrically connected between the ground and one parallel arm resonator different from the at least two parallel arm resonators of the parallel arm resonators. The second inductor is electromagnetic field coupled to at least one of an antenna side matching element, a transmission side matching element, and a portion of the serial arm in the transmission filter. The first and second inductors obstruct electromagnetic field coupling therebetween.

Abstract: A multiplexer includes filters and low pass filters. A second frequency band and a third frequency band are partially different. A first frequency band does not overlap the second frequency band and the third frequency band. One end of the filter is connected to a common terminal and the other end is connected to an input/output terminal. The low pass filter is connected in one end to the common terminal and in the other end to one end of the filter. The other end of the filter is connected to one end of the low pass filter. The other end of the low pass filter is connected to the input/output terminal. One end of the filter is connected to a node between the other end of the low pass filter and one end of the filter and the other end of the filter is connected to the input/output terminal.
