CHIP COUPLING CAPACITOR WITH STANDARD RADIO FREQUENCY SHIELDING STRUCTURE FOR LOWER LOSS

摘要

a capacitor radio frequency (rf) shielding structure can include a ground plane partially surrounding a coupling capacitor in an rf signal path. the ground plane may include a first portion of the ground plane that extends between a positive terminal of the RF signal path and a negative terminal of the RF signal path. the ground plane may include a second portion of the ground plane that extends between the positive terminal and the negative terminal of the RF signal path. the second portion of the ground plane may be opposite the first portion of the ground plane. The capacitor RF shielding structure may also include a standardized shielding layer that comes into electrical contact with the first portion of the ground plane and / or the second portion of the ground plane. the standardized shield layer can electrically disconnect a return current path over the standardized shield layer to confine a return current to run over the first portion of the ground plane or the second portion of the ground plane.
