Abstract:
1. A printed circuit board having an RF IC power stage embedded therein, comprising: a power supply plane, which is formed in a multilayered printed circuit board that several insulation and circuit layers are laminated by turns, has a connection pad region defined therein; a first device, one terminal of which is placed on the connection pad region of the power supply device, which is provided perpendicular to the power supply plane, penetrating to a first insulation layer which is connected to the power supply plane, a first circuit layer which is connected to the first insulation layer, and a second insulation layer which is connected to the first circuit layer and other terminal is connected to a second circuit layer which is connected to the second insulation layer; and, a second device, which is formed in the multilayered printed circuit board and the first circuit layer, the second insulation layer and the second circuit layer which is the different layer form the power supply plane, wherein one terminal is connected to the other terminal of the first device formed perpendicular to the power supply plane, and other terminal is connected to an RF IC mounted in the surface of the multilayered printed circuit board through a second connection via hole.
