Zusammenfassung:First and second transmission line couplers (202, 204) one being configured in an asymmetrical open circuit configuration, the other being configured in an asymmetrical short circuit configuration, are coupled together to form a balun transformer (200). Balun transformer (200, 400, 500) can be implemented in three port bandpass filter (800) or other differential circuits to combine the functionality of a balun transformer and a two-pole filter into one circuit.
