pi−style filters (C−R−C) that reduce EMI/RFI emissions while at the
same time providing ESD protection. This device is custom−designed
to interface with the headset port on a cellular telephone, and contains
three different filter values. Each high quality filter provides more than
20 dB attenuation in the 800−2700 MHz range. These pi−style filters support bidirectional filtering, controlling EMI both to and from the
