The CXG1194XR is a high power SP4T 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 the PCB layout by allowing direct connection of the switch to digital baseband control lines with CMOS logic levels. This switch is SP4T, one antenna can be routed to either of the 2Tx or 2Rx ports. It requires 2 CMOS control lines. The Sony GaAs JPHEMT MMIC process is used for low insertion loss.
