An apparatus for filtering a signal is disclosed. The apparatus includes a conductive line affixed to a surface of a substrate. For a signal received at an end of the conductive line, the apparatus is configured to filter at least a portion of the frequency components of the signal. First and second resistive films are adjacent to a respective side of the conductive line along a first side of each of the first and second resistive films, respectively. The first and second resistive films have a first resistivity. Third and fourth resistive films adjacent to a respective one of the first and second resistive films along a second side of each of the first and second resistive films. Each second side of the first and second resistive films extends beyond the third and fourth resistive films. The third and fourth resistive films have a second resistivity.
