Product data sheet

1. Product proï¬le

1.1 General description

The IP4337CX18/LF is a 7-channel RC low-pass ï¬lter array which is designed to provide

ï¬ltering of undesired RF signals in the 800 MHz to 3000 MHz frequency band. In addition,

the IP4337CX18/LF incorporates diodes to provide protection to downstream components

from ElectroStatic Discharge (ESD) voltages as high as Â±15 kV.

The IP4337CX18/LF is fabricated using monolithic silicon technology and integrates

7 resistors and 14 diodes in a single Wafer-Level Chip-Scale Package (WLCSP)

measuring 1.96 mm by 1.61 mm (typical). These features make the IP4337CX18/LF ideal

for use in applications requiring the utmost in miniaturization.

1.2 Features

I Pb-free, RoHS compliant and free of halogen and antimony (Dark Green compliant)

I Integrated 7-channel Ï-type RC ï¬lter network

I 70 â¦ series resistance; 25 pF (typical) capacitance per line

I Integrated ESD protection withstanding Â±15 kV contact discharge, far exceeding

IEC 61000-4-2 level 4

I WLCSP with 0.4 mm pitch

1.3 Applications

I Cellular and Personal Communication System (PCS) mobile handsets

I Cordless telephones

I Wireless data (WAN/LAN) systems
