CXG1122EN

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 CXG1122EN is used for low insertion loss. An evaluation PCB is available
