SP10T Antenna Switch Module for 8TRx/2Tx CXM3572ER Description The CXM3572ER is a SP10T antenna switch module for GSM/UMTS/CDMA/LTE multi-mode handset. The CXM3572ER has a built-in dual low pass filter and a +1.8 V 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. 0.45 dB (Typ.) TRx (Cellular Band) 0.60 dB (Typ.) TRx (IMT Tx Band) High Linearity: No DC Blocking Capacitors (Except sourcing DC bias) Small Package Size: Lead-Free and RoHS Compliant Structure GaAs Junction Gate pHEMT (JPHEMT) MMIC Switch, CMOS Decoder Absolute Maximum Ratings ◆ Supply voltage This IC is ESD sensitive device. Special handling precautions are required.
