CXG1121TN
SP4T GSM/GPRS Dual-Band Antenna Switch + Logic
Description
The CXG1121TN is one of a range of low insertion
loss, high power MMIC antenna switches for GSM/
GPRS dual-band application. The low insertion loss
on transmit means increased talk time as the Tx
power amplifier can be operated at a lower output
level. On-chip logic reduces component count and
simplifies PWB layout by allowing direct connection
of the switch to digital base band control lines with
CMOS logic levels.
This switch is an SP4T, one antenna can be routed
to either of the 2 Tx or 2 Rx ports. It requires 3 CMOS
control lines (Tx/Rx, GSM900/1800 and Standby).
The Sony GaAs JFET process is used for low
insetion loss. An evaluation PWB is available.

GaAs MMICs are ESD sensitive devices. Special handling precautions are required. The IC will be damaged in
the range from 100 to 200V @200pF 0鈩?and below 1000V @100pF 1500鈩?
