RF Shields

RF Shields are designed to protect both electronic and mechanical components from signal interference. The primary function of any RF shield, regardless of the type or application, is to reduce the surface area exposed to electromagnetic radiation. This reduces the overall signal strength, important for high fidelity signals. RF Shields are designed to keep electromagnetic radiation from entering or leaving an electronic device or component.

47-CBSA-2.75X4.0X0.4 Application Field

The 47-CBSA-2.75X4.0X0.4 RF Shield is designed for use in various types of equipment, such as audio and RF applications. It is primarily used in applications involving low power, high frequency signals. It is also suitable for use with low-voltage, high-frequency power supplies, as well as for many professional audio applications.

This RF Shield can be used in both portable and stationary radio broadcast systems, including AM, FM, Shortwave, and Ultra High Frequency (UHF) bands. This shield\'s low-inductance properties make it suitable for use with digital signal processors, analog-to-digital converters, and other power pulse applications. It is also suitable for high-power radio frequency (RF) amplifiers, providing efficient thermal management and reliable shielding performance.

Working Principle

RF Shields employ Faraday cages or Faraday shields. This refers to a container formed of conductive materials that helps block electric fields. Electromagnetic fields (EMFs) such as radio and microwaves, can be blocked by the Faraday cage, which is formed by a conductive metal sheet or mesh. As the electric field enters the Faraday cage, it is diverted around the conductive material and doesn\'t reach the enclosed components.

In the case of the 47-CBSA-2.75X4.0X0.4 RF Shield, the Faraday cage is formed of a conductive metal sheet, which is then sandwiched between two plates of dielectric material. This dielectric material, which has a high permittivity (or capacitance), helps block the electric fields but doesn\'t interfere with the signal transmission path. The Faraday cage is then further shielded by a thin sheet of conductive material, which reduces the RF signal leakage from the outside of the shield.
