NJG1104KB2
800MHz BAND LNA GaAs MMIC
nGENERAL DESCRIPTION
NJG1104KB2 is a variable gain low noise amplifier (LNA).
At 800MHz band, noise figure is 1.2dB, variable gain range
is 21dB and input 3rd order intercept point is +6dBm. These
characteristics are very suitable for CDMA cellular phone
application.
The variable attenuators placed in front of LNA realize wide
range of input power with low distortion.
Very small and thin FLP6-B2 package is adopted.

PRECAUTIONS
1) The inductor of 1608 size is
recommended for NF
characteristics.
2) The value of C3 is selected
to get lower gain and higher
output IP3.
