DP8T Antenna Switch Module for GSM/UMTS/CDMA Multi-mode Handsets
CXM3570ER
Description
The CXM3570ER is a DP8T antenna switch module for GSM/UMTS/CDMA multi-mode handset.
This IC has a built-in dual low pass filter and a +1.8 V CMOS compatible decoder.
The Sony JPHEMT MMIC process is used for low insertion loss and high linearity.
The device has low BOM with no DC blocking capacitor.
(Application: GSM/UMTS/CDMA multi-mode handset)
Features
 Low insertion loss:
 Low-voltage operation:
0.52 dB (Typ.) TRx (Cellular band)
0.72 dB (Typ.) TRx (IMT Tx band)
VDD = 2.5 V
 No DC blocking capacitor
 Small packing (size):
VQFN-26P (3.0 mm  3.8 mm  0.85 mm Max.)
 Lead-free and RoHS compliant
Structure
 GaAs JPHEMT MMIC switch, CMOS decoder
This IC is ESD sensitive device. Special handling precautions are required.
