Introduction

RF Shields, generally referred to as RF Shields, are designed to minimize unwanted radio frequency interference, commonly referred to as EMI (electromagnetic interference), that can result from electrical and electronic equipment. This type of shielding blocks external interference, thus reducing or eliminating the disruption caused by electromagnetic radiation.

Application Field

25-CBSADV-1.75X1.75X0.325 Shield is the most popular type of RF shield due to its low cost, lightweight construction and wide range of applications. It is typically used for applications requiring a low-profile construction and for managing RF shielding in areas with limited space. This type of shield is suitable for application in areas that require higher frequency attenuation and can be both mounted on the wall and suspended from ceilings. Some of the applications that can make use of this shield are as follows:

• Enclosed electronics such as circuit boards, LAN cards, modems, and wireless routers
• Surge protection for computers, TVs, and radios
• Cellular phone boosters and antennas
• Industrial and medical applications such as X-ray and ultrasound devices.

Working Principle

25-CBSADV-1.75X1.75X0.325 Shield works by containing RF energy within the built-in shield while diverting the energy away from the sensitive electronics inside the cabinet/shield. The energy is typically diverted away from areas that have sensitive components and thus away form the user. The shield makes use of a combination of conductive material such as copper, aluminum or an appropriate non-electrically conductive material such as fiberglass, to create a metallic barrier. The conductive material is either welded or Brazed to a perforated sheet of the same material. As the waves are propagated through the shielding material, they reflect off the radiating surfaces giving rise to attenuation.

Conclusion

25-CBSADV-1.75X1.75X0.325 Shield is a shielding material that is designed for easy installation and a wide range of applications. It is lightweight and provides maximum shielding effectiveness while providing minimal disruption to the intended user. With its low cost and wide range of applications, this shield is an ideal choice for any project that requires RF shielding.
