NJG1103F1
1.5/1.9GHz LOW NOISE AMPLIFIER
GaAs MMIC
nGENERAL
DESCRIPTION
NJG1103F1 is a Low Noise Amplifier GaAs MMIC
designed for 1.5GHz and 1.9GHz band digital cellular
phone and Japanese PHS handsets.
This amplifier provides low noise figure, high gain
and high IP3 operated by single low positive power supply.
This amplifier can be tuned to wide frequency point.
(Best for 1.5GHz or 1.9GHz)
Small package of MTP6-1 is adopted.
