웹2024년 7월 14일 · BALUN TYPES. There are two types of baluns: voltage and current (see Figure 4). A voltage balun forces the balanced output to have equal and opposite voltages. … 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 transform … 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 • Magnetic core 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 communications, particularly in realising frequency conversion mixers to make cellular phone and data transmission networks … 더 보기
