NJRC NJG1104KB2 800mhz band lna gaas mmic Datasheet

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.
nFEATURES
lLow voltage operation
lLow current consumption
lHigh gain
lLow noise figure
lVariable gain control
lHigh input IP3
lHigh output IP3
lUltra small & ultra thin package
