SP10T Antenna Switch Module for GSM and UMTS/CDMA Multi Mode Handset CXM3520BER Description The CXM3520BER is a SP10T antenna switch module for GSM and UMTS/CDMA multi-mode handset. The CXM3520BER 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 (4bands) / UMTS (1band) / CDMA (3bands) multi-mode handset GSM (4bands) / UMTS (2bands) / CDMA (2bands) multi-mode handset, etc. Features Low insertion loss (SP10T): 0.85dB (Typ.) Tx1 (GSM Low band Tx) High attenuation: Low voltage operation: 0.85dB (Typ.) Tx2 (GSM High band Tx) 0.53dB (Typ.) TRx1 (UMTS Band I) 35dB (Typ.) On Tx1 path @1648-1830MHz 33dB (Typ.) On Tx2 path @3420-3820MHz VDD = +2.5V No DC blocking capacitors VQFN-26P (3.0mm × 3.8mm × 0.8mm Typ.) Lead-free and RoHS compliant Small package (Size): Structure GaAs junction-gate PHEMT MMIC switch, CMOS decoder and Dual-LPF. Sony PHEMT GaAs process is utilized for low insertion loss.
