1. A balun transformer, comprising:
a primary inductive circuit having a first terminal and a second terminal located side-by-side and symmetrically to a first axis and on a first side of the balun transformer; and
a secondary inductive circuit having a third terminal, a fourth terminal, a fifth terminal, and at least two loops, the secondary inductive circuit located at a second side of the balun transformer opposite the first side,
wherein the primary inductive circuit and the secondary inductive circuit are disposed on a plane,
wherein the primary inductive circuit includes more loops than the secondary inductive circuit, and
wherein the third terminal and the fourth terminal are located symmetrically to the first axis, the first axis crossing the fifth terminal symmetrically.
