SP9T/10T Antenna Switch Module for GSM and UMTS/CDMA Dual Mode Handset
CXM3519ER
Description
The CXM3519ER is a SP9T/SP10T antenna switch module for GSM and UMTS/CDMA dual-mode handset.
This IC 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 and small mount Area with no DC blocking capacitor.
