SONY CXM3542ER

3P9T Antenna Switch for GSM/CDMA Dual Mode Phones
CXM3542ER
Description
The CXM3542ER is 3P9T anntena switch for quad bands GSM and triple bands CDMA dual mode.
This IC has a decoder circuit which supports CMOS control.
Sony JPHEMT GaAs process is utilized for low insertion loss and high linearity.
(Applications: Quad bands GSM and triple bands CDMA dual mode phones)
Features
‹ Low insertion loss
‹ Low voltage drive: 2.5 to 3.3V
‹ Supports CMOS control
‹ High ESD resistance
‹ Eliminates Output DC Blocking Capacitors to RF ports
‹ Lead-Free and RoHS Compliant
Package
VQFN-34P (3.8mm × 4.4mm × 0.85mm Max.)
Structure
GaAs Junction Gate pHEMT (JPHEMT) MMIC Switch, CMOS Decoder
