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
Š GSM (4bands) / UMTS (1band) / CDMA (3bands) multi-mode handset
Š GSM (4bands) / UMTS (2bands) / CDMA (2bands) multi-mode handset, etc.
Features
‹ Low insertion loss (SP10T): 0.85dB (Typ.) Tx1 (GSM Low band Tx)
0.85dB (Typ.) Tx2 (GSM High band Tx)
0.53dB (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 (Size):
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.
Sony PHEMT GaAs process is utilized for low insertion loss.
Note on Handling
GaAs MMIC’s are ESD sensitive devices. Special handling precautions are required.
