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.
