DP10T Antenna Switch Module for GSM/UMTS Dual Mode Phones

Preliminary

CXM3525ER

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:

1.8V control input

VDD = 2.5V

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.)

Structure

GaAs JPHEMT MMIC Switch, CMOS Decoder
