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 arrangement of either line. A balun can take many forms and may include devices that also … 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 … 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 … 더 보기 • Antenna tuner § balun • Electromagnetic interference • Ferrite bead • Impedance matching 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 and secondary windings, as well as between individual loops in any single … 더 보기 A balun's function is generally to achieve compatibility between systems, and as such, finds extensive application in modern communications, particularly in realising frequency … 더 보기 웹2024년 2월 28일 · The word balun (BAHL-uhn) is a contraction of “ bal anced to un balanced.”. Balance refers to the impedance between either conductor of a two-wire feed line (parallel conductor or coaxial cable) and the antenna … 웹2024년 4월 9일 · RF Baluns, also known as radio frequency baluns or impedance transformers, are essential components in communication systems. They convert unbalanced signals to balanced signals and vice versa. small fire creatures
