<p>An electrical filter structure comprises a first filter core structure (230) and a second filter core structure (240). The first filter core structure comprises a plurality of shunt impedance elements (234a, 234b). Similarly, the second filter core structure comprises a plurality of shunt impedance elements (244a, 244b). Shunt impedance elements of the first filter core structure are arranged in different conducting layers of a multi- layer structure, and shunt impedance elements of the second filter core structure are arranged in different layers of the multi -layer structure. Transmission lines used to implement the shunt impedance elements are interleaved.</p> |
