RF Filters – DEA162450BT-1289A3 Application Field and Working Principle

RF filters play an important role for connectivity and network, making it possible to provide high quality communication. The DEA162450BT-1289A3 is a selectable band-stop filter that is able to provide performance up to 40 GHz. It is mainly used for telecoms and space applications and it is designed as part of a multiplexing system to reject unwanted local frequency signals and to provide a clean output signal. The moving parts of the filter are all enclosed in a shield of metal, which provides protection from external radiations.

Application Field

This RF filter is designed for applications in which its performance characteristics are suited to meet the requirements. It is used for telecoms and space applications where rejection of local frequency signals needs to be achieved with a high degree of accuracy. In addition, it can also be used in other applications such as frequency hopping satellite communications, spread spectrum radio systems and cellular radio systems.

Working Principle

The DEA162450BT-1289A3 works on the principle of frequency selective band-stop filtering. This type of filter is designed to allow certain frequencies to pass through while blocking other frequencies. The device is composed of two filters which are connected in series, each of them consists of two tunable resonators.The device operates by reflecting waves with a specific frequency range, and thus the waves are blocked from passage to the antenna or other components of the system. The transmissions which are allowed to pass are filtered and lower frequency components are attenuated due to the device’s construction.The device is highly sensitive to temperature variations and, as such, it has a wide range of operating temperatures, from -45°C to +85°C. It is also quite difficult to adjust and maintain the filters due to the complexity of their design and the number of components involved.

Conclusion

The DEA162450BT-1289A3 is an RF filter that can provide up to 40 GHz performance. It is mainly used for telecoms and space applications, and it provides a reliable way of rejecting unwanted local frequency signals. The filter works by reflecting waves with a specific frequency range, and thus the waves are blocked from passage, but the transmissions allowed to pass are filtered and their lower frequency components are attenuated. The device is highly sensitive to temperature variations, and it has a wide range of operating temperatures. It is also quite difficult to adjust and maintain the filters due to their complexity, but if the device is operated correctly, it can provide high quality performance.
