Balun

Balun, short for balanced and unbalanced, is an electrical circuit that provides the interface between balanced and unbalanced circuits. It works by converting the single-ended unbalanced signal into the balanced differential signal, enabling the balanced transmission line to transmit signal from one end to the other. The 5800BL15B100E, which is a specified series of impedance-matched balun, is a two-port device that is used to match the source impedance of a 50Ω, 100Ω or 150Ω unbalanced antenna system to the load impedance of a 300Ω balanced antenna system.

5800BL15B100E Application Field and Working Principle

The 5800BL15B100E is useful in FM Broadcasting, Telemetry, Radar, Satellite Communications, Receiving Antennas, Automated Test Equipment and other RF systems that require matching between a 50-150Ω source and a 300Ω balanced load.

When two antennas are used, such as a single 50Ω antenna and a 300Ω antenna, the capacitive reactance of the antennas cancel each other and the total input impedance of the antenna system is constrained to be 300Ω. The 5800BL15B100E is designed to solve this problem by providing an appropriate conversion between the antenna source impedance and antenna load impedance.

A balanced transmission line is necessary for proper operation and performance of the antenna system. The 5800BL15B100E provide a balanced interface between the antenna system and the transmission line. The device consists of two coupled center-tapped transformers, with each transformer consisting of three windings. The windings are connected in a manner to provide the necessary conversion between the source and load.

The 5800BL15B100E consists of two transformer winding, input and output. The input winding is center-tapped and is connected to the output of the transmitting device. The output winding is center tapped and connected to the antenna system.

When using the 5800BL15B100E, the source signal is fed to the input winding of the transformer, which is then converted to a balanced differential voltage across the output terminal. This differential voltage is then applied across the antenna system, which is then converted back to a single-ended voltage across the input terminal.

The 5800BL15B100E provides a convenient and efficient manner to match the source impedance to the load impedance, thus providing the necessary impedance matching for proper signal transmission. The device can also be used to match multiple antennas or multiple matched antennas, such as in the case of a quad antenna system.
