Abstract
A balun includes a first LC resonator, a second LC resonator, a third LC resonator, and a fourth LC resonator. The second LC resonator is magnetically coupled with the first LC resonator. The fourth LC resonator is magnetically coupled with the third LC resonator and electrically connected between a third terminal and a fourth terminal in parallel with the second LC resonator. Each of the first LC resonator and the second LC resonator has a resonant frequency that is a first resonant frequency. Each of the third LC resonator and the fourth LC resonator has a resonant frequency that is a second resonant frequency higher than the first resonant frequency.
