0896BM15E0025E RF/IF and RFID

Baluns are transmission line transformers used to balance electrical or radio-frequency signals between two transmission lines. They are commonly used to match unbalanced coaxial transmission lines or coaxial cable to balanced or unbalanced equipment. The 0896BM15E0025E balun is a more complex model, intended for use in more demanding radio, power, and transmission applications.

Application Field

This balun is designed for signal transmission applications in the frequency range from 7.5 MHz to 300 MHz. Its high power rating and ability to handle wide frequency range makes it suitable for use in many high-power applications, such as transmitters, receivers, amplifiers, and power dividers. It is also ideal for use in communication systems, RF antennas, and radar systems. Furthermore, it is valuable for field communication, broadcasting, and industrial automation systems.

Working Principle

At the heart of the 0896BM15E0025E balun is its coaxial core, which ensures maximum signal transfer between transmission lines. It is an unbalanced/balanced transformer, meaning it is capable of transforming from an unbalanced to a balanced signal, and vice versa. The balun is built with a high dielectric strength ferrite core, which allows it to cover a large frequency range without having to worry about power dissipation. Its low-loss design also ensures that it does not lose too much signal strength during signal transfer. On each side of the balun, there are two 50 ohm terminals which allow simple and reliable connection with long coaxial or balanced cables.

The 0896BM15E0025E balun also has a DC-to-DC voltage calibration feature, which ensures linear performance over its entire operating frequency range. This means the balun will not be affected by changes in the supply voltage. This feature also eliminates the need for component swapping for different voltage calibration requirements.

In addition, the balun boasts excellent shielding performance, with an electric field strength above 5 dB at a frequency of 10 MHz. This ensures a high quality signal which is resistant to electrical and magnetic interference, allowing for enhanced reliability. Furthermore, the balun is housed in a low-profile package which minimises space requirements, making it easier to install in confined areas.
