How a balun works

WebAt RF frequencies, the use of a balun is necessary for correct function of transmitters and antennas. If not, unwanted current flow and mismatches can increase interference … 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.

WebI am familiar with Ruthroff and Guanella baluns, but I am having a bit of a time understanding how this one works. I've reverse-engineered the PCB to get the following schematic (note the dots on the windings): I know that the zener is just there for transient protection and is not part of the actual balun circuitry. 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.
