웹A balun helps maintain the balance of current flowing in the transmission line. In other words it is helping prevent current flow from becoming unbalanced. It is not the device balancing it! PROBLEMS WITH BALUNS WHICH ARE NOT 1:1 RATIOS: Many people think baluns with a high impedance ratio (e.g., 4:1, 6:1, etc.) are a good solution to many ... A balun / ˈ b æ l ʌ n / (from ... The ratio of loops in each winding and the efficiency of the coils' magnetic coupling determines the ratio of electrical potential to electrical current and the total power of the output. For idealized transformers, ... 더 보기 A balun /ˈbælʌn/ (from "balanced to unbalanced", originally, but now dated from "balancing unit") is an electrical device that allows balanced and unbalanced lines to be interfaced without disturbing the impedance … 더 보기 Although baluns are designed as magnetic devices – each winding in a balun is an inductor – all transformers made of real materials also have a small capacitance between the primary … 더 보기 A balun's function is generally to achieve compatibility between systems, and as such, finds extensive application in modern … 더 보기 Classical transformer type In classical transformers, there are two electrically separate windings of wire coils around the transformer's core. The advantage of transformer-type over other types of balun is that the electrically separate windings for … 더 보기 An RF choke can be used in place of a balun. If a coil is made using coaxial cable near to the feed point of a balanced antenna, then the RF current that flows on the outer surface of the coaxial cable can be attenuated.
