RF shields are devices used for blocking electromagnetic radiation from a device, either to protect other devices from the radiation or to reduce the interference effects generated by the radiation. The devices are commonly used in electronic devices to protect sensitive electronic circuitry, to protect personnel from exposure to the radiation, and to block the transmission of undesired signals.

The 23-CBSA-0.75X3.5X0.25 RF shield is a particular device designed to protect electronic circuits and personnel from high frequency (HF) electromagnetic radiation (EMR). It is a shielding enclosure with an integrated metal top lid, side flange, and a bottom support plate. The device functions by absorbing the RF energy and dissipating it internally as heat. This absorption is achieved through the use of a metal cage or faraday cage, which is made of a conductive material such as aluminum.

The 23-CBSA-0.75X3.5X0.25 RF shield is specifically designed for applications with frequencies between 10 and 2,500 MHz, and can accommodate devices with up to 9”x9”x6” dimensions. Its shielding effectiveness is rated at 90dB at 10 MHz, and 55dB at 2,500 MHz when the shield is physically mounted. When used in an open frame with no surrounding metal structure, the shielding effectiveness is reduced to 50dB at 10 MHz, and 25dB at 2,500 MHz.

In terms of its application, the exact field of use for this particular shielding device depends on particular external factors such as the space constraints and application environment of the device it is protecting. Generally speaking, some of the most common applications of this device are for military and aerospace, telecommunications, medical, industrial, and consumer electronics. In these industries, the device is used to reduce EMI (electromagnetic interference) by blocking and absorbing the radiation from surrounding sources and emitters.

In a practical sense, the 23-CBSA-0.75X3.5X0.25 RF shield is simple to install and use. It fits around the device to be protected and is secured with screws or adhesive strips. An internal RF feed through is provided for connecting signal cables, and the shield’s cathode-connected side is internally grounded for ESD (electrostatic discharge) protection. Adequate ventilation should be provided to ensure heat dissipation.

Overall, the 23-CBSA 0.75X3.5X0.25 is an effective shielding device for HF radiation. Its shielding effectiveness is sufficient under most circumstances, when both used in open frames and when mounted to the device being protected. It provides protection against EMI in its specified frequency range, which makes it suitable for many applications in a variety of industries.
