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 module substrate having first and second main surfaces; a semiconductor IC having third and fourth main surfaces and mounted on the first main surface with the third main surface between the module substrate and the fourth main surface; and first and second electrodes extending perpendicularly to the first main surface. The cross-sectional area of the second electrodes is smaller than the cross-sectional area of the first electrodes. The semiconductor IC viewed in plan has first and second sides parallel to each other and third and fourth sides parallel to each other. The first electrodes are distributed over a first region between the first side and a side facing the first side and a second region between the second side and a side facing the second side. The second electrodes are in a third region between the third side and a side facing the third side.
