Patent ID: 8427388

Claim:
A symmetrical eight-shaped balun component, comprising: first and second electrically conductive tracks, the tracks shaped into turns forming a first eye and a second eye; wherein the first conductive track includes an equal number of turns in each of the first and second eyes, and wherein in operation an electrical current flows through the first track in a first direction in the first eye and in a second direction in the second eye, and wherein the first conductive track forms a first conducting path from a first terminal to a second terminal; wherein the second conductive track includes an equal number of turns in each of the first and second eyes, and wherein in operation an electrical current flows through the second track in a first direction in the first eye and in a second direction in the second eye, and wherein the second conductive track forms a second conducting path from a third terminal to a fourth terminal; wherein at least one of the first and second conductive tracks forms successive turns alternately in the first and second eyes; and wherein geometrical and electrical middle points of first and second conductive tracks are all superposed and are located in the same plane in the balun.
