Ceramic filters are electrical filters used for very high frequency signals. The CER0247E ceramic filter is one of the most commonly used products for this purpose by electronic engineers. This article outlines the working principle and application field of the CER0247E.

Working Principle

Ceramic filters rely on the properties of piezoelectric ceramic materials, which vibrate in response to high frequency signals. The CER0247E ceramic filter is designed to use this effect to filter out unwanted signals. In the CER0247E, a series of nested ceramic resonators are arranged in a helical pattern in order to filter out out-of-band signals and noise. The CER0247E is specifically designed to be highly linear and provide excellent out-of-band rejection at very high frequencies.

Filtering Performance

The CER0247E is a high performance ceramic filter, with excellent out-of-band rejection performance. It is capable of rejecting signals up to 100 dBc/Hz out-of-band, and maintains linearity up to 3 GHz. The CER0247E is also low cost, making it an attractive solution for designers looking for an affordable filter.

Application Field

The CER0247E is used in a wide range of applications where high performance filtering is required. It is particularly popular in wireless communication systems, where it is used to provide low loss filtering of RF signals. It is also used in antenna arrays, where it is used to reject unwanted interfering signals. It is also used in industrial sensor systems, where it is used for suppressing interference from external sources. Additionally, the CER0247E is used in automotive electronics, medical electronics, and instrumentation.

Conclusion

The CER0247E ceramic filter is a high performance and low cost solution for designers looking for a high performance filter for their applications. It is particularly popular in wireless communications, antenna arrays, industrial sensors, automotive electronics, medical electronics, and instrumentation. The CER0247E relies on the piezoelectric properties of ceramic materials to reject signals up to 100 dBc/Hz out-of-band, while maintaining excellent out-of-band rejection performance.
