Abstract
A surge suppressor configured to receive signals from a coaxial line having a signal carrying inner conductor and a grounded outer conductor. The surge suppressor includes an inner conductor exhibiting capacitance and configured to connect to the coaxial line inner conductor, an outer conductor configured to connect to the coaxial line outer conductor and to ground, and an inductor formed of a wire encapsulated in an encapsulating material electrically coupling the inner conductor and the outer conductor. RF signals in the surge suppressor's operating bandwidth pass through the surge suppressor relatively unimpeded while electrical surges will be diverted through the inductor to the outer conductor, and therefore to ground, and possible residual pulses will be blocked from passing through the surge suppressor by the capacitance.
