CIRCUIT AND METHOD FOR AN ELECTRICAL FILTER

An electrical filter circuit (300) is disclosed. The circuit (300) includes a first input line (301) and a second input line (302). A first transmission line (313), (413), (513), (613) is coupled electrically in series at a first node (325), (425), (525), (625) with a first output line (335), (435),...

Zusammenfassung:An electrical filter circuit (300) is disclosed. The circuit (300) includes a first input line (301) and a second input line (302). A first transmission line (313), (413), (513), (613) is coupled electrically in series at a first node (325), (425), (525), (625) with a first output line (335), (435), (535), (635), and an inductor (L1), (L2), (L3) is coupled electrically in series between the first input line (301) and the first transmission line (313), (413), (513), (613). The filter also includes a second transmission line (327), (427), (527), (627) having a first impedance coupled to the first node (325), (425), (525), (625). The second input line (302) is coupled electrically in series at a second node (326), (426), (526), (626) with a second output line (336), (436), (536), (636). A third transmission line (328), (428), (528), (628) is coupled to the second node (326), (426), (526), (626), and a capacitor (C1), (C2), (C3) is coupled electrically in series between the second transmission line (327), (427), (527), (627) and the third transmission line (328), (428), (528), (628). The first output line (335), (435), (535), (635) has a second impedance that is greater than the first impedance.
