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, includes a connection pad electrically insulated therefrom; a first device, one terminal of which is placed on the connection pad of the power supply plane, and the other terminal of which is placed on the power supply plane; and a second device, which is formed in a different layer from the power supply plane of the multilayered printed circuit board, is connected to the first device through a first connection via hole formed on the power supply plane, and is connected to an RF IC mounted in the multilayered printed circuit board through a second connection via hole formed on the surface of the multilayered printed circuit board; wherein the first device is one of a resistor and an inductor; and the second device is a decoupling capacitor.
