RF Filter

Radio frequency filter, also known as "radio frequency interference filter", is mainly used in high-frequency electronic equipment to attenuate high-frequency interference signals generated by high-frequency electronic equipment.

With the rapid increase of the operating frequency of electronic equipment, the frequency of electromagnetic interference is also getting higher and higher, and the interference frequency usually reaches hundreds of MHz, or even above GHz. Because the higher the frequency of the voltage or current, the easier it is to generate radiation. It is these high-frequency interference signals that cause the problem of radiation interference to become increasingly serious. Therefore, there is an urgent need for a filter that can greatly attenuate the high-frequency signals of radiation interference. This filter is a radio frequency interference filter.
