A multilayer printed circuit board (100) includes a plurality of layers (101, 102, 104, 106, 108 and 110). Located within intermediate layer (106) is an inductor (200) which is shielded by top layer ground plane (202) and bottom layer ground plane (204). In another embodiment of the present invention, the inductor (200) can have its inductance adjusted by way of an inductance adjustement runner (316, 318) or by an electronic inductance adjustement device (408).
Une carte à circuit imprimé multicouche (100) comporte une pluralité de couches (101, 102, 104, 106, 108 et 110). Une bobine d'inductance (200) blindée par le plan de masse de la couche supérieure (202) et de la couche inférieure (204) est intégrée dans la couche intermédiaire (106). Dans un autre mode de réalisation, l'inductance de la bobine d'inductance (200) peut être réglée au moyen d'une broche de réglage de l'inductance (316, 318) ou d'un dispositif électronique de réglage de l'inductance (408).
