RF filters are incredibly useful in a variety of modern technological applications, and the DEA165850LT-1197B2 is no exception. This filter offers a particularly attractive combination of selectivity, insertion loss, and low power consumption, making it an ideal choice for a variety of applications. In this article, we discuss the DEA165850LT-1197B2, including its application fields and working principles.

Application Field

The DEA165850LT-1197B2 is a high-performance RF filter that is suitable for use in a wide variety of applications. This filter is designed for use in frequency bands of 400 MHz to 2400 MHz, making it a good choice for applications such as cellphone base stations, cellular base station, satellite communications, and more. The filter is also suitable for equipment such as wireless routers, microwave links, and more.

In addition, the DEA165850LT-1197B2 can be used for applications that require a high level of selectivity. This filter is able to reject interference signals with a return loss of 13 dB at 400 MHz to 2200 MHz, while still offering high-performance insertion loss across the entire operating frequency band. As such, it is a great choice for applications that need to minimize interference.

Working Principle

The DEA165850LT-1197B2 is an electronic filter based on the SAW filter principle. Specifically, it combines Silicon and quartz technology to create a low-power, low-cost RF filter. The filter is made of two layers of interdigital transducers (IDT) and one layer of ground plane. The IDT layers are composed of a series of interdigital capacitors which are connected in parallel and are used to filter out frequency components that are outside of the desired frequency range.

Each of the IDTs is connected to an RF input port and an RF output port, allowing for the filtered signal to be received and amplified by the RF amplifier. The grounded plane is used to dissipate noise and suppress interference. In addition, the SAW filter utilizes a low-profile design, which allows for a high-performance, low-power RF filter to be created at a relatively low cost.

Conclusion

The DEA165850LT-1197B2 is an excellent example of an RF filter that utilizes the SAW filter principle. This filter offers a high level of selectivity, minimal insertion loss, and low power consumption, making it suitable for a wide variety of applications. Its low-profile design also allows for a cost-effective solution that can be used in a wide range of frequency bands. The DEA165850LT-1197B2 is an ideal choice for applications that need to minimize interference and improve signal quality.
