A radio frequency module includes a substrate having a first major surface and a second major surface that face each other, a first component disposed on or over the first major surface of the substrate, a second component disposed on the first component, a third component disposed on or over the first major surface of the substrate, and a metallic body connected to a ground. One end of the metallic body is connected to the first major surface of the substrate; and in plan view, the metallic body is disposed between the first component and the third component.

Radio frequency module and communication device

To provide a radio frequency module and a communication device capable of achieving reduction in height. The radio frequency module includes a mounting substrate and one or more chip inductors. The mounting substrate has a recess at least one end of both ends in a second direction orthogonal to a first direction that is a thickness direction of the mounting substrate. A second chip inductor that is at least one chip inductor of the one or more chip inductors is disposed in the recess.

There is provided a radio-frequency module and a communication device with which miniaturization can be achieved and quality deterioration can be suppressed. A radio-frequency module includes a mount board on which a ground terminal is disposed, a first chip, a second chip, and a cover (a shield cover). The first chip is disposed on the mount board. The second chip is disposed on the first chip. The cover covers at least a part of the first chip and at least a part of the second chip. The second chip has a first connection terminal (a ground terminal) on an opposite side from the first chip in a thickness direction of the mount board. The cover includes a shield layer connected to the ground terminal disposed on the mount board. The first connection terminal is connected to the shield layer.
