RF Shields

RF shields are designed to resist, dissipate, or otherwise shield RF energy and eliminate or minimize the level of electro-magnetic emissions. Shielding is widely used in electronic and electrical systems to guard against the radiation of RF energy or interfere with propagation. RF shielding materials can be tailored to specific needs and applications depending on their characteristics, such as permeability, specific absorption loss, linearity, loss tangent, material temperature, and surface finish.RF shielding is a type of metal shielding that is commonly used in a variety of applications, ranging from medical and telecommunications devices such as cell phones and laptops to audio equipment and industrial machinery. It is used in applications such as aerospace, commercial, industrial, military and scientific, where protection from RF fields is essential. RF shielding is also used to protect people and equipment from hazardous levels of RF radiation in industrial, commercial, and residential environments.The 56-CBSA-1.75x3.0x0.5 (“Counter Balanced Shield Applications”) shield is a low-frequency, two-piece RF shield that provides a high level of performance. It is designed for applications where it is necessary to protect against high RF fields, typically in the frequency range of 0.1MHz to 10MHz. The common applications of this shield include broadcast transmitters, RF attenuators, antennas, radar systems, medical equipment, and telecommunication systems.It is composed of two formed halves, which are counterbalanced to ensure uniform shielding performance regardless of the orientation. This is achieved by balancing the inductance of the two halves using the same inductive surface area, such that one half has equal and opposite reactance to the other. The counterbalance also allows for higher current transfer between two terminals for increased shielding strength.The 56-CBSA-1.75x3.0x0.5 shield is designed for two-piece operation in standard point-to-point applications such as cable entries. The two halves of the shield are connected through one or more of the four threaded terminal connections, which form a complete circuit with minimal leakage. The threaded terminals are designed to fit many standard RF connectors, including RCA, SMA, and TNC.The two-piece construction of the 56-CBSA-1.75x3.0x0.5 shield offers improved shielding with lower insertion loss than single-piece shields. Furthermore, the two-piece design eliminates the need for tamper-proof fasteners, which saves on labor and cost. The uniform size of the connected shields also ensures a consistent and reliable fit, regardless of usage or orientation.The 56-CBSA-1.75x3.0x0.5 shield is designed to be very effective in providing a high level of shielding performance and protection against RF fields. It is well-suited for use in a variety of applications, such as telecommunication systems, medical equipment, broadcast transmitters, antennas, radar systems, and RF attenuators. The two-piece design ensures uniformity of performance and flexibility of usage, while the threaded terminals allow for secure terminals and minimal leakage.
