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.

0.88dB (Typ.) Tx2 (GSM High Band Tx)
0.50dB (Typ.) TRx1 (UMTS Band I)
Low insertion loss (SP9T): 0.85dB (Typ.) Tx1 (GSM Low Band Tx)
0.85dB (Typ.) Tx2 (GSM High Band Tx)
0.47dB (Typ.) TRx1 (UMTS Band I)
High attenuation: 35dB (Typ.) On Tx1 path @1648 – 1830MHz
33dB (Typ.) On Tx2 path @3420 – 3820MHz
Low voltage operation: VDD = +2.5V
No DC blocking capacitors
Small package: VQFN-26P (3.0mm × 3.8mm × 0.8mm Typ.)
Lead-Free and RoHS compliant
Structure
GaAs Junction-gate PHEMT MMIC Switch, CMOS Decoder and Dual-LPF.
