SP8T Antenna Switch for GSM/UMTS
The CXG1228XR is a high power SP8T antenna switch for GSM/UMTS 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 component count and simplifies PCB layout by allowing direct connection of the switch to digital
baseband control lines with CMOS logic levels. It requires 3 CMOS control lines. The Sony GaAs JPHEMT
MMIC process is used for low insertion loss.
