CXG1122EN

16 pin VSON (Plastic)

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.

Features

• Insertion loss: (Tx) 0.5dB typ. at 34dBm (GSM900)

• 3 CMOS compatible control lines

• Low second harmonic: –40dBm typ. at 34dBm (GSM900)

• Small package size: 16-pin VSON (2.7mm

× 3.5mm × 0.9mm)

Applications

Triple-band handsets using the combinations of followings:

• GSM900/DCS1800/PCS1900

• GPRS

• DECT
