The DUST-SHLD01 is a unique RF shield used to protect digital systems from exposure to radio frequency interference (RFI). This type of RF shield is ideal for applications where there is a need for low-cost shielding of a variety of sources of radiation. The shield utilizes a copper-plated steel frame and welded construction, which are resistant to RF dust induction.

Application Field

The DUST-SHLD01 provides effective shielding performance in a variety of application fields. It is ideal for applications that require shielding of wireless communication systems, such as cellular networks, satellite communications, and Wi-Fi networks. It is also commonly used in medical facilities, military bases, and laboratories.

Working Principle

The DUST-SHLD01 utilizes a Faraday cage principle, which is based on the depolarization of the frequency spectrum of the electromagnetic field. The shield provides a conductive enclosure that blocks external electrical impulses, maximizing the effectiveness of the shielding. The device is designed to effectively block radiation in the frequency range of 890 MHz to 6 GHz, providing effective shielding from frequency hopping and spread spectrum signals.

The shield utilizes a three-dimensional shielding system which is designed to absorb, reflect, and attenuate external RF signals and protect the equipment within the shield from their effects. The shield is constructed of a series of copper-plated steel ribs, which are welded together in a three-dimensional shape. This provides an effective shield from RF interference caused by electrical and electronic devices, and other sources such as radio and TV stations.

The DUST-SHLD01 also features an internal grounding grid that is designed to efficiently dissipate static electricity and reduce any RF signatures that may be emitted from sensitive components. This reduces interference, thus ensuring that the desired frequency is maintained without disruption.
