3-1-6WL Balun: Application Field and Working Principle

A Balun is a type of transformer which is used to provide an impedance transformation between two circuits, whereas 3-1-6WL Balun is a kind of Balun. It helps to match the impedance between the feedback part and transmission line. It is widely used in DVB-S/S2/S2X, DAB, DMB-T/H/A, and 5G communication systems, especially in antenna systems. This article will explain how a 3-1-6WL Balun operates and what its application field looks like in more detail.

Working Principle

3-1-6WL Balun is basically composed of three cores in a U-shaped iron core, which is composed of two parts of U-shaped cores, and two parts of U-shaped cores are connected with windings. A reasonable winding is accurate to the number of turns, so that the symmetry of electromagnetic coupling between two U shapes is better, and the mutual inductance between two U shapes has a good linear relationship. With this structure, the 3-1-6WL Balun can match the system impedance and reduce the reflection between the feed system and the transmission line. Specifically, a 3-1-6WL Balun uses cores and windings to build a transformer, which allows transformation of the low-frequency signal in a signal path into a high-frequency signal. This transformation is converted by the transformer through the two U-shaped cores, and the signal is then transmitted through the transmission line. When the signal reaches the antenna, the U-shaped core inside the 3-1-6WL Balun works as a filter, which ensures that only specific frequencies and signals are passed through to the antenna.

Application Field

Most 3-1-6WL Baluns are used in antennas, as they provide a matching impedance between the feeding part and the transmission line. Such a Balun’s impedance can be adjusted and matched with the transmission line’s impedance, which helps to ensure that the signals that reach the antenna are the right frequency and energy levels. As a result, a 3-1-6WL Balun provides a better communication link, which makes it a must-have in DVB-S/S2/S2X, DAB, DMB-T/H/A, and 5G communication systems.In addition, a 3-1-6WL Balun is also used in cable television systems. These systems require the signal transmission from one source to multiple receivers, where a 3-1-6WL Balun provides an impedance transform from one circuit to multiple circuits. As a result, the ideal 3-1-6WL Balun helps to increase the signal strength and reduce power loss in the process of transmission.

Conclusion

In conclusion, 3-1-6WL Balun is a kind of Balun. It works by transforming low-frequency signals into high-frequency signals using U-shaped cores and windings, which is then transmitted through a transmission line. 3-1-6WL Balun is widely used in antenna systems, and it also provides a good matching impedance between the feeding part and the transmission line. Furthermore, 3-1-6WL Balun is also widely used in cable television systems for signal transmission from one source to multiple receivers.
