Abstract: A radio frequency module has a substrate, a first chip inductor, an integrated circuit, and a first amplifier connected to the first chip inductor. The first chip inductor is on a first main surface of the substrate and the integrated circuit is on a second main surface of the substrate, the second main surface being opposite the first main surface. The integrated circuit includes the first amplifier. When the substrate is viewed from a direction perpendicular to the first main surface of the substrate, the first chip inductor at least partially overlaps the integrated circuit.

Abstract: A radio frequency circuit includes a substrate, a first terminal disposed on a first principal surface of the substrate, a second terminal disposed on the first principal surface, a first-surface mounted component disposed on the first principal surface or inside the substrate, and a second-surface mounted component disposed on a second principal surface of the substrate which is opposite the first principal surface. A radio-frequency signal, which is input to the first terminal, is transmitted, for output from the second terminal, so as to make at least one round trip between the first principal surface and the second-surface mounted component, which is disposed on the second principal surface, through wiring lines disposed in the substrate.

Abstract: A radio-frequency module includes a multilayer substrate, an input switch, an output switch, and filters. A switch IC is disposed on a main surface of the multilayer substrate. The input switch is disposed in the switch IC and includes a first input terminal and first output terminals. The output switch is disposed in the switch IC and includes second input terminals and a second output terminal. The filters are disposed outside the switch IC and are connected to the first output terminals and the second input terminals. In a plan view of the multilayer substrate, the first input terminal and the first output terminals are disposed close to a first side of an exterior of the switch IC, and the second input terminals and the second output terminal are disposed close to a second side different from the first side of the exterior of the switch IC.

Abstract: A radio-frequency module includes switch elements, first signal paths, band pass filters, first matching circuits, second signal paths, and second matching circuits. Each of the first signal paths is connected between one end of a corresponding one of the switch elements and an antenna terminal. Each of the band pass filters is connected to a corresponding one of the first signal paths and allows a radio-frequency signal of one of the plurality of frequency bands to pass therethrough. Each of the first matching circuits is connected to a corresponding one of the first signal paths. Each of the second signal paths is connected to a corresponding one of the switch elements. Each of the second matching circuits is connected to a corresponding one of the second signal paths. A component included in the first matching circuits and a component included in the second matching circuits are electromagnetically coupled.

Abstract: A high-frequency module includes a mounting substrate, a first filter, a second filter, and a third filter. The mounting substrate has a first main surface and a second main surface opposite to each other. Simultaneous communication is enabled for the first filter and the second filter, and the third filter is not used in the simultaneous communication using the first filter and the second filter. The first filter, the second filter, and the third filter are mounted on the first main surface of the mounting substrate. A first substrate of the first filter, a second substrate of the second filter, and a third substrate of the third filter are common to each other. The third filter is disposed between the first filter and the second filter in plan view from a thickness direction of the mounting substrate.
