General Description

The CM1414 is a low-pass filter array designed specifically to reduce EMI/RFI emissions and provide ESD protection for a headset port on a cellular and mobile devices.

The CM1414 integrates two high quality, pistyle filters (C-R-C) filters, one for a microphone and one for an earpiece or speaker, each providing more than 35dB attenuation relative to the pass band attenuation in the 800-2700 MHz range.

These filters support bidirectional filtering, reducing EMI both to and from the headset port and support bipolar audio signals without distortion.
