Abstract
Symmetrical eight-shaped balun (BALanced-to-UNbalanced converter) comprising a first and second eye, each eye comprising conducting tracks forming turns. The eyes comprise an equal number of primary turns that form a first conducting path from a first terminal to a second terminal, in which in operation electrical current flows in a first direction in a first eye and in a second direction in a second eye. Moreover, the eyes further comprise an equal number of secondary turns that form a second conducting path from a third terminal to a fourth terminal, in which in operation electrical current flows in a first direction in a first eye and in a second direction in a second eye. The geometrical and electrical middle points of primary and secondary turns are all superposed and further are located in the same plane.
