CXM3519ER - SP9T/10T Antenna Switch Module

General 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.
