Description :

NJG1123PB5 is a Triple band LNA IC designed for W-CDMA / UMTS cellular phone of 2.1GHz, 1.7GHz and 800MHz band.

This IC has the function which bypasses LNA, and high gain mode or low gain mode can be chosen.

High IIP3 and a low noise are achieved at the High gain mode.

And low current consumption can be achieved at the low gain mode because LNA enters the state of the standby.

An ultra small and ultra thin package of FFP16-B5 is adopted.
