Rev. 02 — 20 August 2009
Product data sheet
1. Product profile
1.1 General description
The IP4337CX18/LF is a 7-channel RC low-pass filter array which is designed to provide
filtering 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 ±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 π-type RC filter network
I 70 Ω series resistance; 25 pF (typical) capacitance per line
I Integrated ESD protection withstanding ±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

7. Application information
7.1 Insertion loss
The insertion loss measurement configuration of a typical 50 Ω NetWork Analyzer (NWA)
system for evaluation of the IP4337CX18/LF is shown in Figure 3.
As an example, the insertion loss of channels between pins A2 and A5, A1 and A4,
B1 and B5, C1 and C4 at frequencies up to 6 GHz is displayed in Figure 4.
The insertion loss is measured with a test PCB utilizing laser drilled micro-via holes that
connect the PCB ground plane to the IP4337CX18/LF ground pins.
