Background and Application Field

Radio Frequency (RF) shields are designed to block undesired RF signals from being transmitted or received, while allowing desired signals to pass through. They can prevent interference with other communications systems, prevent RF leakage, and reduce signal interference. 14RA-CBSA-2.25X2.5X0.13 is a RF shield designed for the most common type of shield technology used in the mobile radio industry - the balanced microstripline. It is often used in high end applications such as cellular base stations, ground station antennas, and high power military RF systems. It is also used in applications such as automotive RF communications, RF test benches, and other mobile communications.

Design and Working Principle of 14RA-CBSA-2.25X2.5X0.13

14RA-CBSA-2.25X2.5X0.13 is an RF shield designed with a balanced microstrip line. It is made from boards of alternating conductors and insulators with the ratio of these two components chosen to provide the maximum reduction in signal leakage. The board is designed in a hermetically sealed package to reduce the introduction of external interference and enhance the shielding effectiveness. The shield is designed to work in the frequency range of 824 to 894 MHz and provides a shielding effectiveness (SE) of 85 dB in this range. The SE is the ratio of the RF signal that enters the sealed package to the RF signal that is reflected. This level of attenuation is similar to that of modern RF systems such as mobile phones. The shield is also designed to be highly efficient in its ability to attenuate RF signals. It has an absorption level of 99.5%, meaning that only 0.5% of the incident signal is transmitted through the shield. This combination of high SE and efficiency means that the 14RA-CBSA-2.25X2.5X0.13 is ideal for applications that require high levels of signal attenuation and shielding effectiveness.

Summary

The 14RA-CBSA-2.25X2.5X0.13 is a radio frequency shield designed with a balanced microstrip line. It is designed for use in applications where high levels of signal attenuation and shielding effectiveness are required. The shield is designed to work in the frequency range of 824 to 894 MHz and provides a shielding effectiveness (SE) of 85 dB, with an absorption level of 99.5%. This makes it ideal for applications such as cellular base stations, ground station antennas, and military RF systems.
