Abstract
An electrical filter structure for forwarding an electrical signal from a first filter port to a second filter port in a frequency-selective manner includes a filter core structure having a working impedance, wherein the working impedance is different from a first characteristic port impedance of a first filter port, and also different from a second characteristic port impedance of a second filter port. The electrical filter structure also includes a first matching arrangement electrically coupled between the first filter port and the filter core structure and a second matching arrangement electrically coupled between the second filter port and the filter core structure.
