Integrated USIM/SIM card passive filter arrays with ESD protection

The IP4264CZ8-20 and IP4264CZ8-40 are 3-channel RC low-pass filter arrays which are designed to provide filtering of undesired RF signals in the 800 MHz to 3000 MHz frequency band. In addition, the IP4264CZ8-20 and IP4264CZ8-40 incorporate diodes to provide protection to downstream components from ElectroStatic Discharge (ESD) voltages as high as +-15 kV contact and > +-15 kV air discharge, far exceeding IEC 61000-4-2, level 4.

The IP4264CZ8-20 and IP4264CZ8-40 are fabricated using monolithic silicon technology and integrate three resistors and seven high-level ESD-protection diodes in a 0.4 mm pitch 8-pin Micropak (compatible with QFN) lead-free plastic package with a height of only 0.5 mm. These features make the IP4264CZ8-20 and IP4264CZ8-40 ideal for use in applications requiring component miniaturization, such as mobile phone handsets, cordless telephones and personal digital devices. The device is also available in wafer level chip-size package WLCSP8, with 0.4 mm pitch (IP4364CX8/LF) and 0.5 mm pitch (IP4064CX8/LF).
