A coupler comprises a first line (31) and a second line (32) which is broadside coupled to the first line (31) in a first and a second section (42, 53). The capacitance between the first and the second line (31, 32) per length unit of the first line (31) is larger in the first section (42) in comparison to the second section (53). The first and the second line (31, 32) form a first turn (40). |
