NJG1670LG3
SP10T ANTENNA SWITCH GaAs MMIC
! 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.

PRECAUTIONS
[1] For good RF performance, the ground terminals should be directly connected to the ground patterns and
the through-holes as close as possible by using relatively wide pattern.
[2] Please connect exposed GND PADs (bottom side of IC) to PCB GND using through holes.
