RF filters are electronic components used in both transmitting and receiving applications to pass or block signals of certain frequencies while allowing other signals to go through. The DEA205425BT-2028A4 belongs to that type of filters.

Application Field

The DEA205425BT-2028A4 is one of the best solutions for clients using technologies that require ultra frequency bandwidth, narrow-bandwidth and high power RF filters.Some of the applications for the DEA205425BT-2028A4 are implementations in Global Navigation Satellite Systems (GNSS) and services such as the Global Positioning System (GPS) which require superior protection against rejection in low- and no-connectivity situations as provided by its ultra-low PIM rating for optimal performance in extreme temperature and extreme humid conditions. It is also applicable for Wi-Fi, WiMAX, and satellite systems where broadband and high-power filtering is needed.Additionally, its ultra-low Insertion Loss, small size, and low profile are suitable for applications where size and weight are important such as on aircraft navigation systems, airborne antennas, base station equipment, and other devices.

Working Principle

The DEA205425BT-2028A4 works as a low-pass filter. It has two connections for input and output signals and an internal resonator to reduce the harmonic content of all signals. This ensures that any unwanted signals of higher frequencies are eliminated.

The internal resonator, which is used to reduce the harmonic content of all signals, is formed by a high-performance dielectric resonator filter. This type of filter is a particularly efficient and miniaturized way of generating a wide range of stopband attenuations. It also ensures that the DEA205425BT-2028A4 has a very low insertion loss and therefore keeps the powerloss from the filter to a minimum.

In conjunction with the filter capabilities of the DEA205425BT-2028A4, its input and output ports also benefit from a high return loss value which prevents the reflection of energy back to the source. This minimizes losses and interference, improving the overall functionality of the RF filter.

The DEA205425BT-2028A4 is a highly efficient filter due to its design which combines the dielectric resonator filter in combination with high quality diplexers. Its superior design and performance makes it an ideal solution for a variety of applications where broadband filtering is required.

Conclusion

The DEA205425BT-2028A4 is a powerful and effective filtering tool capable of offering top-of-the-line performance in a variety of applications. Its unique design and low insertion loss makes it capable of delivering full-frequency bandwidth without compromise. Its multifunction capabilities contribute to its wildly successful utilization in such areas as GNSS and Wi-Fi, WiMAX, and satellite systems.
