Abstract
Systems and devices for transmitting radio frequency signals to and from radio frequency coils in magnetic resonance imaging systems are provided. In one embodiment, a balun for blocking induced radio frequency current on ground conductors of a multi-layer signal carrier includes first and second insulative elements disposed on first and second sides of the signal carrier, respectively, a conductive layer partially surrounding ends of each insulative element with a central region of each insulative element not surrounded by the respective conductive layer, first and second capacitive circuits coupled to the conductive layers of each respective insulative element in the central region thereof, vias extending through the signal carrier, and conductive material disposed in the vias electrically coupling a conductive layer on respective ends of the first and second elements with one another and with the ground conductors.
