General Description
The NJG1670LG3 is a GaAs SP10T antenna switch IC designed for GSM/CDMA/UMTS multimode handsets. This switch features very small package size (3.2mmx2.5mmx0.85mm), high linearity, low insertion loss and high isolation. The NJG1670LG3 contains a switch die with on-chip logic circuits,ESD protection circuits and a LTCC substrate with built-in two LPFs on GSM transmit paths for suppression of transmitter harmonics. For saving current consumption,The NJG1670LG3 has a sleep mode.
