Abstract: A balun circuit is disclosed. The balun circuit has an unbalanced port and a balanced port, wherein the balanced port comprises a first terminal, and a second terminal. The balun circuit further comprises a main line having a first end and a second end, the first end being coupled to the unbalanced port. Moreover, the balun circuit comprises a first sub-line electromagnetically coupled to the main line, the first sub-line having a first end and a second end, wherein the first end of the first sub-line is coupled to the first terminal of the balanced port. The balun circuit further comprises a second sub-line electromagnetically coupled to the main line, the second sub-line having a first end and a second end, wherein the first end of the second sub-line is coupled to the second terminal of the balanced port.
