RF shields provide a range of solutions for shielding electromagnetic radiation so that interfering signals by the nearby electronic devices can be eliminated. Radio frequency (RF) shields reduce the amount of RF that can pass through the enclosure, thus providing the protections and shielding performance. Usually, a RF shield is comprised of a conductive material that is designed to be highly efficient and resist interference. Thus, it can keep the signal frequency within certain level, prevent rapid signal decay, and attenuate the signal better.

22-CBSA-2.5X5.5X0.2 is the item number for a type of RF shields supplied by Cofan USA. It is a two-way milled-shields for RF protection with a dimensional size of 2.5 x 5.5 x 0.2 inches. This type of RF shield is designed for enclosures that require superior shielding and protection. The material of the RF shield is Brass 0.8mm, and it features an excellent shielding effectiveness of over 20dB.

The application field of 22-CBSA-2.5X5.5X0.2 RF shields can be categorized into four industry sectors. Firstly, it can be used in the aviation, aerospace, defense industries for RF protection in communication systems, radar systems and also various electronic systems. Also, the RF shielding applications for this type of shields go to the civil assemblies, as it is in a great demand in the wire-laying and connecting projects. Thirdly, they are being applied in the health medical industries to protect the medical images like MRI scans, x-rays and other images for potential signals interference. Lastly, they are used in the industrial areas such as agricultural areas, electronic appliances and other environments which may affect the signal flow and need electromagnetic radiation shielding protection.

In terms of their working principle, the 22-CBSA-2.5X5.5X0.2 RF shields shall be installed and connected properly to make the shield works fine. The conductive material of the shield can shield against the incident RF signals either by absorbing the energy, or reflecting the energy away from the protected area. The interferers on the other side of the shield will be reflected away from the protected area due to the impedance difference and the properties of the RF shield materials.

Therefore, the interference shall be reduced and the RF signal within the protected area will be maintained. The shielding effectiveness shall depends on the design, the materials used and the installation of the RF shields. The 22-CBSA-2.5X5.5X0.2 RF shields shall block the interference generated by the nearby electronic devices to a certain level upon installation. The advantages of using this type of RF shield include its strong enclosure strength and robust construction.
