<p>The filter (2) has primary and secondary positively coupled inductive elements (L42, L46) arranged in series between a primary input terminal (22) and a primary output terminal (26). Third and fourth positively coupled inductive elements (L44, L48) are arranged in series between a secondary input terminal (24) and a secondary output terminal (28). Capacitive elements (C41, C43) and a fifth inductive element (L49) are arranged in series between each of midpoints (21, 23) of series connections of the inductive elements and ground, where the filter is in integrated shape.</p> |
