Common Mode Chokes, or CMCs, are devices commonly used in communications systems to help reduce unwanted interferences and to maintain uniform DC bias levels in different components of a system. The CAV-3.6-0.47 is one of these devices. It is a high-performance CMC designed to reduce disturbances in the tower-link installation system. This article will discuss the application field and working principle of the CAV-3.6-0.47.

In a tower-link system, the CAV-3.6-0.47 CMC is used to reduce unwanted noise and to maintain a stable DC bias level. It is designed to provide excellent control over both common-mode and differential-mode bipolar to unipolar conversion. It is also able to suppress harmonic noise that can be generated by switching-type power supplies or other power sources.

The CAV-3.6-0.47 is capable of providing a wide range of frequencies for improved performance. This CMC operates over a frequency range of 10.7 MHz to 3.6 GHz with an insertion loss of 0.47 dB for frequencies up to 1.0 GHz. For frequencies between 1.0 and 3.6 GHz, the insertion loss is 0.42 dB. The DC bias level is kept stable with a maximum deviation of ± 0.2dB. The large size of the CAV-3.6-0.47 also makes it suitable for high-current applications. It is able to handle currents up to 1.4 amp at 25°C.

In addition, the CAV-3.6-0.47 CMC has a wide range of application fields. It is suitable for use in cellular and microwave communications, digital cellular networks, power line communications, and other systems where high data rates are needed. It is also suitable for other applications such as industrial automation systems, where it is used to reduce EMI/RFI noise.

The CAV-3.6-0.47 CMC operates on the principle of EMC (electromagnetic compatibility). It works by providing a low-impedance connection between two lines, thereby reducing noise interference and maintaining a constant DC bias level between the two lines. This CMC consists of a high-current winding with two series-connected coils that are wound on a ferrite core. These coils form a parallel LC circuit which helps to reduce impedance. The CMC also contains a high-frequency decoupling capacitor to ensure good high-frequency performance.

In summary, the CAV-3.6-0.47 is a high-performance CMC used to reduce disturbances in the tower-link installation system. It is designed to provide excellent control over both common-mode and differential-mode noise and also has a wide range of application fields. Finally, it works on the principle of EMC, providing a low-impedance connection between two lines, thereby reducing noise interference and maintaining a constant DC bias level between the two lines.
