摘要

An electromagnetic interference (EMI) suppression technique for gigahertz (GHz) frequency region of hard disk interconnector, namely trace suspension assembly interconnector (TSAI) is presented. The BSR-1 absorber is selected and filled in between conductor traces of the interconnector. The attenuation of radiated and conducted EMIs are calculated and analyzed by using simulation software based on finite integral technique. From the results, it is found that the proposed technique can suppress radiated EMI from 16 uV to 0.5 uV in all frequency regions up to 20 GHz and the conducted EMI can be suppressed up to 0.7 Watt in a range of 0.9 GHz -4.0 GHz with the same structure of TSAI.
