Application

With the rapid increase of the operating frequency of electronic devices, the frequency of electromagnetic interference is also higher and higher. The interference frequency usually reaches hundreds of MHz, or even above GHz.Because the higher the frequency of the voltage or current, the more likely to produce radiation, it is these very high frequency interference signals lead to the problem of radiation interference is becoming more and more serious.Therefore, it is urgent to have a kind of filter which can attenuate the high frequency signal of radiated interference. This RF filter is the RF interference filter.
