21-CBSA-3.5X4.75X0.225

RF Shields are used in a wide range of applications, from industrial electronics to television and radio transmission, to keep Radio-Frequency (RF) Waves from radiating from their sources. The particular shielding referenced by the label 21-CBSA-3.5X4.75X0.225 is used in high-power radio frequency applications, such as in satellite communication. It serves to protect the equipment and components from the high-powered RF signals that would otherwise radiate away from the source.The shielding itself is made of highly conductive material, such as copper or aluminum, and is in the form of either a mesh or solid plat. This material is then sealed in an insulated casing that is designed to limit the amount of radiation that is able to escape. The material employed by the 21-CBSA3.5X4.75X0.225 is a highly conductive copper foil with a dielectric layer to enhance insulation. The dielectric layer helps reduce the effects of multipath interference.The shielding works by providing an attenuation of the output signal, which won’t escape from behind the shield. The attenuation depends on the frequency of the signal. The higher the frequency, the lower the output signal. The signal is also partially attenuated by heating the shield itself. This heat causes the electrons in the material to move slower so that they are not able to move out as far from the signal origin. In addition to heating, the shield can also be cooled down in order to maintain a constant environmental temperature.The shielding also serves to protect human personnel from exposure to the RF Radiation. It also prevents cross-talk between components that are close together, as well as blocking external interference from coming in to the established signal.In summary, the 21-CBSA-3.5X4.75X0.225 RF Shielding is used in high power radio frequency applications, such as satellite communication. The shielding itself is made of a highly conductive material, such as copper or aluminum, and is in the form of either a mesh or solid plat. This material is then sealed in an insulated casing that is designed to limit the amount of radiation that is able to escape. The shielding works by providing an attenuation of the output signal, which won’t escape from behind the shield. It also serves to protect human personnel from exposure to the RF Radiation and to block external interference.
