Choke BalunBALUNS (short for "balanced-unbalanced") is an
electronic device that converts signals between balanced and unbalanced
transmission lines. It is commonly used in radio frequency (RF) systems,
including antennas and transmission lines, to ensure proper impedance
matching and reduce signal loss or interference. Baluns come in various
designs, each tailored to specific applications.
Key Functions:Impedance Matching: - Ensures efficient transfer of power between components with differing impedances (e.g., between an antenna and a coaxial cable).
Balanced to Unbalanced Conversion: - Allows
a balanced signal (e.g., from a dipole antenna) to connect to an
unbalanced system (e.g., a coaxial cable) without introducing noise or
distortion.
Reduction of Common-Mode Currents: - Suppresses
unwanted current that may travel along the shield of a coaxial cable,
which can cause signal degradation or interference.
