摘要:
The present invention relates to a power delivery network for providing electric current from a power supply to a radio frequency device mounted on a printed circuit board. The power delivery network comprises: the printed circuit board; the power supply; a radio frequency device adapted to draw an electric current from the power supply, varying in time, with frequencies in a predetermined frequency range; a connection line for providing the electric current from the power supply to the radio frequency device, wherein the connection line is connected to the power supply at one end thereof and to the radio frequency device at an other end thereof, and the connection line shows a parasitic impedance in the predetermined frequency range; a first capacitor coupled between the one end of the connection line and ground of the printed circuit board; a second capacitor coupled between the other end of the connection line and ground of the printed circuit board, wherein the connection line and the first capacitor form the first branch of a parallel circuit, the second capacitor forms the second branch of the parallel circuit, the first capacitor is configured such that in the predetermined frequency range, the resonance frequency of the parallel circuit is only determined by the parasitic inductance of the connection line and the capacitance of the second capacitor, and the second branch of the parallel circuit is configured to decrease the quality factor of the parallel circuit in such a way that the impedance seen by the radio frequency device towards the power supply is lower than a predetermined impedance in the predetermined frequency range.
