Balun Transformer General Information
Surface Mount Balun Transformer General Infornation
What is Balun Transformer?
Balun is name of device that can be like a common mode choke, unbalance to balance transformer, or a step up or down transformer. Balun is an acronym of BALanced UNbalanced, it’s used to convert an unbalanced signal to a balanced one or vice versa. A balun transformer is a device that: ● joins a balanced line (one that has two conductors, with equal currents in opposite directions, such as a twisted pair cable). ● to an unbalanced line (one that has just one conductor and a ground, such as a coaxial cable). Baluns isolate a transmission line and provide a balanced output. A typical use for a balun is in a television antenna. Balanced: A method of transmitting signals using two signal lines. One line carries the source signal; the other carries a signal of opposite phase (antiphase). Unbalanced: A method of transmitting signals using one signal line, with a ground line providing a reference potential.
Why Use a Balun?
Baluns are used for two primary reasons: ● One : Eliminate “common mode current” on the transmission line. ● Two : Matching antenna impedance to the transmission line.

Balun Transformer General Information
Insertion Loss (dB) Loss due to transmission from primary dot port to secondary dot port and secondary port. Most balun transformers are symmetrical through their central horizontal axis, therefore, an input can be applied at the primary dot port or the primary port with differential outputs at the secondary dot and secondary ports. Basics of Broadband Transformers There are two kinds of broadband transformers. One is known as a conventional type, which has separate primary and secondary windings, as do power and audio transformers. The other type is called a transmission-line transformer. It is believed that the latter variety is the most efficient of the two. Transmission-line transformers are wound with twisted or parallel windings and produce specific integers of impedance transformation, such as 4:1, 9:1, and 16:1. Conventional transformers permit you to obtain any transformation ratio you need.
Applications of Balun Transformers
In a balun transformer, one pair of terminals is balanced, that is, the currents are equal in magnitude and opposite in phase. The other pair of terminals is unbalanced; one side is connected to electrical ground and the other carries the signal. Balun transformers can be used between various parts of a wireless or cable communications system. Some common applications denotes as following: ● Television receiver (Balanced) - coaxial cable network or Coaxial antenna system (Unbalanced) ● FM broadcast receiver (Balanced) - Coaxial antenna system (Unbalanced) ● Dipole antenna (Balanced) - Coaxial transmission line (Unbalanced) ● Parallel-wire transmission line (Balanced) - Coaxial transmitter output, or Coaxial receiver input (Unbalanced) Token’s baluns provide impedance transformation in addition to conversion between balanced and unbalanced signal modes. Most television and FM broadcast receivers are designed for 300-ohm balanced systems, while coaxial cables have characteristic impedances of 50 or 75 ohms. Impedance-transformer baluns with larger ratios are available and used to match high-impedance balanced antennas to low-impedance unbalanced wireless receivers, transmitters, or transceivers.

TCB4F SMD Balun Transformers
SMD Common Mode Balun Transformers
SMD Common Mode Balun Transformers For USB - TCB4F Series
Surface Mount Common Mode Balun Transformer (TCB4F) For USB
Preview Token Electronics has introduced SMD common mode transformers (balun transformers) in 3.8 x 4.4 mm compact size, which are used to convert between unbalanced-balanced signals in the antenna inputs of tuner circuits for terrestrial digital broadcast compatible compact devices. Up to now balun transformers have been made by winding wire around a spectacle-shaped ferrite core, and are widely used in electronic devices such as TVs and desktop PCs. Token SMD choke coils common mode TCB4F series are primarily designed for choking power lines and conform to the RoHS compliant and Lead-free. SMD TCB4F can be customed designs and tighter tolerances available on request. Windings use paired or and triple wires for high uniformity. Base pins are end proccessed to allow direct mounting on PCB. Ideal for use in double balanced mixers, and as broad band transformers, transistors and for impedance conversion. Application of SMD choke coils specific designs also available including different inductance values and Q specifications adjusted to frequency requirements. Token is equipped to design and produce custom components to meet many design and reliability demands. Custom parts are available on request. Token will also produce devices outside these specifications to meet specific customer requirements, please contact our sales for more information. Features : - Pair and triple wire coil for high stability and high balance. - Available in tape & reel for automatic surface mounting.. Applications : - Double Balance Mixers. - Broad-Band Transformers. - Impedance Transformers. - Common Mode Filter, Balun Transformers.
