RF Shields are devices specially designed to protect various RF circuits from outside interference. They act as barriers that transmits which helps prevent signal from entering, allowing the circuit to only interact with what lies within the shield’s confines. 2118721-2 is a type of RF Shield and this article will discuss its application field and working principle.

Application Field

2118721-2 is often used in applications of the telecommunications industry. It can be used to protect low noise amplifiers (LNAs) such as the ones used in base station receiver applications, as well as the antennas themselves. It can also be used to provide enclosures for wireless communication systems for various wireless protocols like WiFi, Bluetooth, etc. In general, 2118721-2 is used to provide a protective layer around various RF circuits that could be vulnerable to interference.

Working Principle

The working principle of the 2118721-2 RF Shield is based on the concept of field cancellation. It is designed to create an electromagnetic field that is evenly distributed around the device, acting as a shield against outside interference. This effect is achieved via the use of a Faraday cage which is essentially a metal box that is placed around the device, acting as a shield that prevents the passage of RF signals.

The 2118721-2 RF Shield is also equipped with an additional layer of protection which is the use of an E-field shield. This type of shield is designed to reflect incoming RF waves back to their source, preventing them from reaching the device within the shield. This provides an additional layer of protection to the device from outside interference.

Conclusion

In conclusion, the 2118721-2 RF Shield is a highly effective tool for protecting radio frequency (RF) circuits. It can be used in a variety of applications, such as the telecommunications industry, and offers an additional layer of protection with the use of an E-field shield. By using field cancellation and Faraday cage techniques, 2118721-2 RF Shield creates an electromagnetic field that is evenly distributed, acting as a shield against outside interference.
