A balun is an electrical transformer that is used to convert electrical signals to and from balanced and unbalanced signals. They are normally used to connect lines that have different levels of impedance and are commonly used in the home for connecting HD and traditional antennas. Baluns are als...
All transformers have a limited bandwidth, so the bandwidth of the balun must be designed to be greater than that of the antenna or other system with which it will be used. Concept of an antenna balun The most obvious method of creating a balun is to create a transformer with two ...
One can connect the taps over the transformer using distinct conversion ratios. As it has no separate coils, they do not give isolation · Balun Transformers This allows the interface of unbalanced and blanched lines without affecting the arrangement of impedance on either side. · Current Sense ...
An Unun, short for Unbalanced to Unbalanced, is a type of transformer used in RF antenna systems to match impedance between an unbalanced antenna and an unbalanced transmission line. It is designed to convert the impedance of the antenna to a value that is better suited for the transmission l...
An HDMI extender takes the HDMI connection from a source in one end and converts it into an Ethernet connection using a balun, or balanced to unbalanced transformer. You can then run single, or multiple Cat 5e or Cat 6 Ethernet cables over much greater distances, and connect them to receiv...
Like the original models, such as Ed Wolfrum’s Wolfbox, modern passive DI boxes typically use a form of balun transformer to convert high-impedance signal to low-impedance signal. This style of transformer features electrically separate windings in the input and output stages, which isolate grou...
Established in 2010, Zhuhai Eastever Electronics is a over 10years experience and powerful enterprise factory based in south of china, which is good at making Magnetic Passive components. The company is now mainly engaged in the customization of RF ...

What is a 4 1 UNUN used for? In order to bring the impedance within the range of a good external or built-in asymmetric antenna tuner, a 4/1 UNUN(Unbalanced to Unbalanced) impedancetransformer is used, as a pre-match unit. The UNUN assures reasonable low VSWR values on the coaxial ...
