Baluns (balanced-to-unbalanced) are passive electronic components mainly used for signal transmission and impedance matching. Baluns are predominantly used to convert unbalanced signals to balanced signals, giving them excellent performance in applications such as audio and video transmission, as well as other applications where electrical resistance must be accurately matched. baluns are especially handy when working with electrical equipment that has both balanced and unbalanced inputs and outputs. For example, a radio may require a balanced input but the output of a speaker could be unbalanced.

ETC1-1T-2TR is a popular type of balun which is primarily designed for transmission of audio and video signals from medium frequency to ultra high frequency (UHF) range. The common application areas of the ETC1-1T-2TR balun are HDTV, distribution of digital signals, antenna systems and various wireless communication applications. It is also used in some special frequency radio applications. The ETC1-1T-2TR balun can be used with virtual time domain reflectrometry (VTR) testing.

The ETC1-1T-2TR balun is comprised of two Ferrite-core toroidal coils connected in parallel at the output. The two coils are designed to produce an inductive output current which is proportional to the input AC voltage. The two Ferrite-core toroid coils are connected via two twisted lines. One forms the input terminal and the other forms the output terminal, to which the signal is transferred. The two toroidal coils in the balun are connected via two multi-stranded conductors that are wound in a clockwise direction. The two copper strands are symmetrical in order to ensure that equal current is generated in both the coils.

The two conductors are also wound in a way that the magnetic field lines generated by them are confined to the two toroidal coils and do not escape. This helps to reduce electromagnetic radiation. The winding method of the two coils in the ETC1-1T-2TR is also optimized for maximum signal transfer efficiency. The two coils are connected via an electrical resistance of typically 1 ohm. The ETC1-1T-2TR balun also has the option of tapping the outputs and combining it with an external load in order to achieve a higher power transfer efficiency.

The ETC1-1T-2TR balun has a wide frequency range from 1 MHz to 500 MHz. The effectiveness of the balun is best at frequencies between 3GHz to 400GHz. The balun exhibits low insertion loss when operating in ranges between 4GHz to 400GHz with a loss of approximately 0.02dB at 300GHz. The balun is also effective in reducing noise floor and harmonic distortion on audio signals. The ETC1-1T-2TR balun also exhibits very good return loss characteristics when used in UHF applications.

The ETC1-1T-2TR balun is a highly efficient and reliable component which can be used for a variety of applications. Its low loss and good return loss characteristics make it ideal for use in audio and video transmission applications. Its wide frequency range and low insertion loss further contribute to its usefulness in a wide variety of applications. The ETC1-1T-2TR is an excellent choice for wireless communication and antenna systems where low loss, high power transfer efficiency and low harmonic distortion are important.
