NJG1122PB4
W-CDMA Dual LNA GaAs MMIC
QGENERAL DESCRIPTION
QPACKAGE OUTLINE
The NJG1122PB4 is a Dual band LNA IC designed for W-CDMA
cellular phone of 2.1GHz and 800MHz band.
This IC has a LNA pass-through function to select high gain mode
or low gain mode.
An ultra small and ultra thin package of FFP12–B4 is adopted.
