Abstract
Various embodiments relate to a base station element and related method of suppressing an alternating-current (AC) portion of a signal. A base station element includes a filter capable of lightning suppression through the use of an LC filter that suppresses an AC portion of a received signal while passing a DC portion of the signal. The LC filter includes a flat inductor disposed in a cavity of the base station. The flat inductor may be connected to other electrical components disposed in the cavity of the base station to complete the electrical circuit. In some embodiments, the flat inductor may be produced from one material through photo-etching and may also include snap in or snap on connectors on one or both ends to enable galvanic contact with other components like a tap pin or a printed circuit board (PCB) without requiring attachment through soldering.
