Balun: 2-4-6WEL application field and working principle
A balun is a kind of transformer that converts between a balanced 2-wire line and an unbalanced single-wire line. In radio frequencies, its main purpose is to convert the unbalanced transmission line signaling used in the radio frequency system to balanced transmission line signaling. By doing so, the power loss and signal interface problems are resolved, and the signal transmission is more stable and reliable.
2-4-6WEL balun is a special kind of balun which is designed to facilitate multi-wire balanced transmission. This balun is equipped with two, four or six-wire ports, which can simultaneously transmit two, four or six signals from one side to the other. The signals are transmitted at the same time over the same line and are balanced to reduce power loss.
Application fields
2-4-6WEL balun is widely used in the fields of radio transmission, communication, data transmission, signal transmission, audio-video transmission, fiber optics communication, antenna measurement and so on, it is especially suitable for areas where two, four or six-wire balanced transmission is needed.
The most typical application of 2-4-6WEL balun in radio transmission is the complete transmission of base stations. In order to achieve full transmission in base stations, usually two or four-wire balanced signals is needed to transfer from one end to the other end. In this case, the 2-4-6WEL balun can be used for balanced signals transmission, high power amplifier, filter, antenna feeder, etc.
Working principle
2-4-6WEL balun is based on the principle of the Faraday shield. It changes the voltage of the input port to the same size voltage or negative voltage, and output to the output port through the shield, which enables the balanced voltage and current to be output. In the physical layer of a digital system, balanced transmission can improve signal quality, reduce EMI/RFI interference and reduce power loss.
Besides, the working principle of 2-4-6WEL balun is also related to the principle of mutual inductance. Mutual inductance refers to the phenomenon that current through one coil will induce current in another coil in the same magnetic field. 2-4-6WEL balun utilizes this phenonmenon to achieve balanced transmission signals, while also reducing uplink and downlink transmission noise, which makes it more suitable for radio transmission.
Conclusion
In summary, 2-4-6WEL balun is a special kind of balun used for multi-wire balanced transmission. It is widely used in such areas such as radio transmission, communication, data transmission, signal transmission, audio-video transmission, fiber optics communication, antenna measurement, etc. The working principle of 2-4-6WEL balun is based on the principle of the Faraday shield and the principle of mutual inductance. It changes the input voltage to the same size voltage or negative and transmits it through the shield, thus enabling the balanced voltage and current to be output.
