GSM 900/1800/1900 DUAL/TRIPLE BAND RX/TX
PRELIMINARY DATA SHEET
Description
Structure
The CXA3343ER is a single chip transceiver for
the RF section of GSM handsets. It is designed
to connect directly to the Si4133G Dual
PLL+VCO from Silicon Labs to provide a small
size GSM/GPRS class 12 solution. A high IF
allows the post LNA SAW filters to be replaced
with cheaper Image Reject matching circuits.
