Current Baluns. Current baluns allow each output terminal's voltage, with respect to "ground" or chassis, to float to any value required to provide equal currents to each feedline conductor. Current baluns are universal devices that work with balanced or unbalanced loads equally well.

Key uses for the 1:1 current-balun: a) is to marginalize the “inverted-L current” in the transmission-line feeding a dipole-antenna. This will prevent a radiating Feedline and prevent distorting the antenna’s radiation pattern.

Current baluns are universal devices that work with balanced or unbalanced loads equally well. Current baluns add common-mode isolation between systems connected at each end. While traditionally used as baluns, they work well as broadband phase-invertors or as an un-un.

"1:1 current balun" is a functionally oriented name for a 1:1 Guanella transformer. 1:1 Guanella transformer is the unambiguous name for a type of transformer that can be used for various purposes, including current balun, common mode choke, phase inversion, etc.

2014年10月22日 · This paper described the 1:1 transmission line transformer on top, the basis of our surface mount and 10 GHz and below connectorized baluns, as a current balun. This is because they force the currents to be equal and opposite, regardless of …

Current Baluns. A Current Balun is one whose output currents are equal and opposite (balanced with respect to ground). With the exception of the 1:1 current balun, current baluns are more expensive to construct than voltage baluns and thus are less widely used.

The current-balun (Guanella) puts equal current into/out-of its output terminals; highly desired feature. The voltage-balun (Ruthroff) puts equal magnitude voltages at its output terminals. 11. It is important to comment on the impressive frequency range of a well-designed current-balun.

There are two general classes of baluns: the voltage balun and the current balun. The voltage balun forces equal voltage across the two sides of a balanced load and the current balun forces equal current through the two sides of a balanced load.

Current Balun. The current balun consisted of 15 turns of RG-178/U coaxial cable on an FT82-61 core. Performance was evaluated by connecting the output end to 27 and 54-ohm resistors to ground, and measuring the voltages across them.

2020年7月9日 · There are two main modes of baluns: current baluns and voltage baluns (see Figure 3). Current baluns operate by forcing equal currents on both balanced lines, effectively eliminating common-mode currents.
