CM1412 Overview
The CM1412 is a dual, low−pass filter array integrating two pi−style filters (C−R−C) that reduce EMI/RFI emissions while providing ESD protection. This part is custom−designed to interface with a microphone port on a cellular telephone or similar device. Each high quality filter provides more than 35 dB attenuation in the 800 to 2700 MHz range.
