Abstract
A surge protector comprises an internal circuitry configured to isolate a premise device from a surge input. In one embodiment, the internal circuitry can comprise a first signal path and a second signal path that is inductively coupled to the first signal path. Each of the first signal path and the second signal path can comprise windings, such as the windings that are found in an RF transformer. The internal circuitry can also comprise a blocking element, which is coupled to the second signal path so that the blocking element receives the surge input before the premise device.
