RF shields are used in many different applications for protecting against electro-magnetic radiation. In addition to preventing interference from external sources, they also serve to block signals from being transmitted from one device to another. The 25-CBSA-0.75X1.75X0.225 is a type of RF shield that can be used in applications to limit or block electromagnetic interface. In order to understand how the shield works, it is important to examine its application field and working principle.

Application Field

The 25-CBSA-0.75X1.75X0.225 is typically used for applications with operating frequencies of 400 MHz to 6 GHz. It can also be used in applications up to 8 GHz, though performance may not be as good. The shield is ideal for use with cell phones, routers, base station controllers, Bluetooth accessories, and any other device that requires protection from interference.

Working Principle

The main way a 25-CBSA-0.75X1.75X0.225 works is through its design. It is made up of three parts: the baseplane, the intermediate plane, and the cover. The baseplane consists of copper strips with gaps in-between, and is designed to absorb most of the electromagnetic radiation. The intermediate plane is a DC blocking capacitor which serves to prevent any DC leakage in the application. Finally, the cover is a conductive foil which obscures the RF wave, and reflects back any electromagnetic radiation that is present.

Additionally, the shield also limits the propagation of the RF waves through the use of an impedance plane. This is a type of reflector which helps to control the electromagnetic energy so that it reflects away from the application and does not interfere. The shield also operates on dissipative shielding principles, which involves using a resistive material to create a buffer between the application and the external source.

The 25-CBSA-0.75X1.75X0.225 is designed for applications that need to protect against high levels of electromagnetic radiation. It works by absorbing, blocking, and reflecting the radiation while maintaining a low DC leakage. Its application field is ideal for cell phones, routers, and any other device that needs a reliable shield to prevent interference.
