20-CBSFN-1.0X3.0X0.75

Introduction

RF shield is commonly used in electronic components and subsystems for preventing RF interference. Shield reduce the radiation of interference signal, which greatly improve the signal quality of the overall system.One kind of RF Shields is 20-CBSFN-1.0X3.0X0.75.

Application field

20-CBSFN-1.0X3.0X0.75 can be used in mobile communication device, Radar, Communication base station, aerospace or defense fields. It support wireless network such as 3G, 4G, 5G, Wi-Fi, LTE, and more. Of special interest is that it perfectly satisfies the shielding performance requirements of receivers with the spectrum of 10Hz to 10GHz.

Working Principle

The 20-CBSFN-1.0X3.0X0.75 is an aluminum-zinc alloy material ,with precise outer dimension size, high shielding performance and high thermal conductivity. It is formed by die casting, with a reduced thickness of 0.75 and utilizes the shielding effect by threading. Its main function is to reduce the operating noise of the broadcasting system.The electromagnetic current flows through the material via conduction, and before being discharged, external interference frequency is effectively absorbed because of its size, and the differential oscilaiton in the cavity is reduced.That is why the shield effectively eliminates external interference and reduces the temperature rise.

Conclusion

In a word, 20-CBSFN-1.0X3.0X0.75 RF shield has many advantages, which make it perfect for many application fields, such as mobile communication device, Radar, Communication base station, aerospace, or defense. It supports a wide range of frequencies, and offers great shielding performance to block external interference to the system. Especially, it also has excellent thermal conductivity to keep the temperature rise low.
