Abstract:
A balun circuit includes a first CPW line 11, a second CPW line 12a, and a third CPW line 12b that serve as signal input/output ports; a first CPS line 14a that is a differential transmission line, the first CPS line 14a relaying the first CPW line 11 to the second CPW line 12a; a second CPS line 14b that is a differential transmission line, the second CPS line 14b relaying the first CPW line 11 to the third CPW line 12b; and at least one connection section that connects grounded conductors of each of the first CPW line 11, the second CPW line 12a, and the third CPW line 12b.
