A Balun is a device designed to connect two circuits by converting or unconverting balanced and unbalanced loads. The characteristics are frequency range, impedance -unbalanced/balanced, phase difference, insertion loss, and return loss. The frequency range is from 10kHz to 23.6GHz with an impedance from 1:1 to 100/100Ohm and a phase difference from -155° ±15° to 195°.
