Abstract
An unbalanced-to-balanced converter (balun) comprising three distributed-constant lines. In one distributed-constant line, a standing wave is generated. Disposed adjacent thereto is another distributed-constant line to which the power of the standing wave is transferred. A signal input to the unbalanced-to-balanced converter is divided into two signals having phases 180 degrees apart and the same level.
