SP4T Antenna Switch CXG1234XR Description The CXG1234XR is an SP4T antenna switch. On chip logic reduces component count and simplifies PCB layout by allowing direct connection of the switch to digital baseband control lines with the CMOS logic levels. It requires 2 CMOS control lines. The Sony GaAs JPHEMT MMIC Process is used for low insertion loss. Features Insertion loss: 0.40dB (Typ.) @960MHz 0.50dB (Typ.) @2170MHz Lead-Free and RoHS compliant Package Small package size: 16-pin XQFN (2.3mm × 2.3mm × 0.35mm) (Typ.)
