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.

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
