Generation Background Of RF Filter
Apr 13, 2018

With the rapid increase of electronic equipment working frequency, the frequency of electromagnetic interference is also more and more high, the frequency of interference will usually reach hundreds of MHz, even above GHz. Because the frequency of voltage or current is higher, the more likely the radiation is, it is these high frequency interference signals that cause the problem of radiation interference is increasingly serious.

Therefore, there is an urgent need for a high frequency signal radiation interference attenuation of the filter appears, this filter is the RF interference filter.

The effective filtering frequency range of the common interference filter is a khz to MHz, and the effective filtering frequency of the RF interference filter is from several khz to GHz.
