NJG1673LG3
SP9T ANTENNA SWITCH GaAs MMIC
I GENERAL DESCRIPTION
The NJG1673LG3 is a GaAs SP9T 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 NJG1673LG3 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 NJG1673LG3 has a sleep mode.
