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.

Features
• Insertion loss (Tx) 0.5dB typical at 34dBm (GSM900)
• 3 CMOS compatible control lines
• Low second harmonic, –40dBm typical, at 34dBm (GSM900)
• Small package size: 16-pin TSSOP (3.9mm × 4.1mm × 1.2mm)

Applications
• Dual-band handsets using combinations of GSM900/GSM1800/GSM1900
• GPRS class 12 handsets
