Abstract
An electrical filter structure includes a first filter core structure and a second filter core structure. The first filter core structure includes a plurality of shunt impedance elements. Similarly, the second filter core structure includes a plurality of shunt impedance elements. 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.
