UHF BAND LOW NOISE AMPLIFIER GaAs MMIC
QGENERAL DESCRIPTION QPACKAGE OUTLINE
NJG1131HA8 is a low noise amplifier GaAs MMIC designed for
mobile digital TV application (470~770 MHz).
This IC features good gain flatness, and low gain characteristic
in out-of-band. This IC achieves low current consumption, low
noise figure and low distortion. Also, this IC is integrated the
ESD protection circuit.
An ultra-small and ultra-thin package of USB6-A8 is adopted.
QFEATURES

[1] C1 is a DC-Blocking capacitor, and L1 is a DC-feed inductor.
[2] L2, L3, and C2 formed the output matching circuit.
[3] C3 is a bypass capacitor.
[4] Ground terminals (1pin, 3pin and 4pin) should be connected with ground plane as close as possible
in order to limit ground path induction.
[5] All external parts are placed as close as possible to the IC.
