DP10T Antenna Switch Module for GSM/UMTS Dual Mode Phones
Preliminary
Preliminary
CXM3525ER
Description
The CXM3525ER is a DP10T anntena switch module for GSM/UMTS dual mode handset.
The CXM3525ER 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 low insertion loss and high linearity.
(Applications: GSM /UMTS Dual Mode handsets)
Features
‹ Low insertion loss :
‹ High attenuation:
‹ Low voltage operation:
1.10dB (Typ.) Tx1 (GSM Low band)
1.05dB (Typ.) Tx2 (GSM High band)
0.40dB (Typ.) UMTS 800M (UMTS Band V)
0.80dB (Typ.) UMTS 2G (UMTS Band I)
25dB (Min.) On Tx1 path @1648-1830MHz
25dB (Min.) On Tx2 path @3420-3820MHz
VDD = 2.5V
‹ 1.8V control input
‹ No DC blocking capacitors required on RF ports
‹ Small package (Size):
VQFN-30P (3.4mm × 4.0mm × 0.85mm Max.)
‹ Lead-free and RoHS compliant
Package
VQFN-30P (3.4mm × 4.0mm × 0.85mm Max.)

GND Plate A and GND Plate B must be separated each other.
GND impedances of Plate A and Plate B should be as low as possible.
GND Terminals of Pin7, 9, 14, 15 must be isolated. And besides not connect to GND Plate A or B.
GND Terminals of Pin 2 and 23 must be connected to GND Plate A.
GND Terminals of Pin 11, 12 and 18 must be connected to GND Plate B.
GND impedances of Pin 14 and 15 are sensitive to attenuation performance.
It is recommended the GND inductance of Pin 14 is about 0.5nH.
It is recommended the GND inductance of Pin 15 is about 0.69nH.
