WebIn an ideal balun, signals appearing at the output of balanced ports are of equal amplitude and differ in phase by 180º. In reality, even in a well designed balun/transformer, there is a small amplitude and phase unbalance. Amplitude unbalance is difference in amplitude (in dB) and phase unbalance is deviation from 180º phase, in degrees. Web26 de fev. de 2024 · How a Balun Works. A balun works by choking off the outer current sometimes found on the shields of coaxial cables. This function helps restore balanced antenna operation which is required for proper functioning. In respect to dipole antennas, the term balanced means currents flow equally on each side or arm of the antenna. high molybdenum steel
