CXM3558ER [SP10T Antenna Switch Module for 4TRx/2Tx/4Rx ]

>>Description

The CXM3558ER is a SP10T antenna switch module for GSM and UMTS/CDMA multi-mode handset.
The CXM3558ER has a built-in dual low pass filter and a +1.8V CMOS compatible decoder.
The Sony GaAs junction gate pHEMT (JPHEMT) MMIC process is used for low insertion loss and high linearity. The device has low BOM with no DC blocking capacitor.

>>Applications

GSM/UMTS/CDMA multi-mode handset
