Now let us consider the proposed balun which is pictorially sketched in fig. 2, where the 50-ohm antenna is again visualized as two 25-ohm resistors in series. The. /4 and the 3/4 adapting sections result to be both terminated on 25 ohm (the SWR. on those sections is then 2:1). 웹2024년 1월 2일 · 1:1 Guanella Current Balun. Requiring a balun to feed a balanced feed line with an un-balanced T-Match tuner, a 1:1 Guanella Current balun design using a L15 ferrite toroid core was selected among others. A current balun may be for most situations the most suitable balun however due the extremely low and high impedances often encounter with ...

For example, the common mode voltage baluns described by Guanella [23], which can have a 1:1 or 4:1 impedance ratio, or the common mode voltage balun described by Ruthroff [22] with a 4:1 impedance ratio can be used. Transmission line …
offshore wellhead웹A technique for designing impedance-transforming baluns is presented in this paper. It is based on the Marchand balun with two identical coupled lines. By varying the coupling factor of the coupled sections, a wide range of impedance transforming ratios can be achieved.
