Patent attributes
A radio frequency module includes: a module substrate including a first principal surface and a second principal surface opposite to each other; a first electronic component (e.g., power amplifier) disposed on the first principal surface; a second electronic component (e.g., low-noise amplifier) disposed on the second principal surface; post electrodes disposed on the second principal surface; and a plated shield wall disposed on the second principal surface and set at a ground potential. Here, the post electrodes include a first post electrode through which a first radio frequency signal is input or output, and a second post electrode through which a power-supply signal is input or output. In a plan view of the module substrate, the plated shield wall surrounds one of the first and second post electrodes, and at least part of the plated shield wall is disposed between the first and second post electrodes.
