US 6,975,496 B2 · Isolated shield coaxial surge suppressor

Abstract

A surge protection device is disclosed that includes a conductor for receiving an rf signal and a dc current, a first shield having a lumen configured to accommodate at least a portion of the conductor, and a second shield having a lumen configured to accommodate the first shield so that a portion of the first shield is positioned within the lumen of the second shield. The surge protection device further includes a dc blocking device, coupled to the conductor, for attenuating the dc current, a device, coupled to the conductor, for diverting the dc current to the second shield, and a dielectric disposed between the first shield and the second shield for preventing the dc current from traveling from the second shield to the first shield.
