NJG1125PB5
W-CDMA Triple LNA GaAs MMIC
QGENERAL DESCRIPTION
NJG1125PB5 is a Triple band LNA IC designed for W-CDMA
/UMTS cellular phone of 2.1GHz, 1.7GHz 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 FFP16–B5 is adopted.
