CXG1122EN
SP5T GSM Triple-Band/GPRS Antenna Switch
Description
The CXG1122EN is one of a range of low insertion
loss, high power MMIC antenna switches for GSM/
GPRS triple-band, dual-band (CXG1121TN) and
applications. 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 the component count and simplifies the PCB
layout by allowing the direct connection of the switch
to digital baseband control lines with the CMOS logic
levels.
This switch is an SP5T, one antenna can be routed
to either of the 2 Tx or 3 Rx ports. It requires 3 CMOS
control lines (CTL1, CTL2 and Tx ON).
The Sony's GaAs JFET process is used for low
insertion loss. An evaluation PCB is available.
