Preliminary
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 :
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)
‹ High attenuation:
25dB (Min.) On Tx1 path @1648-1830MHz
25dB (Min.) On Tx2 path @3420-3820MHz
‹ Low voltage operation:
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.)
