Integrated 4-, 6- and 8-channel passive filter network with ESD protection

The devices are a family of 4-, 6- and 8-channel RC low pass filters which are designed to provide filtering of undesired RF signals on the I/O ports of portable communication or computing devices. In addition the devices incorporate diodes to provide protection to downstream components from ElectroStatic Discharge (ESD) voltages up to ±20 kV.

The PEMIxCSP family is fabricated using monolithic silicon technology and integrates up to eight resistors and 16 protection diodes in a single Wafer Level Chip-Size Package (WLCSP).

These features make the devices ideal for use in applications requiring the utmost in miniaturization such as mobile phone handsets, cordless telephones and personal digital devices.
