NJG1152KA1
Wide Band Low Noise Amplifier GaAs MMIC
GENERAL DESCRIPTION
The NJG1152KA1 is a fully matched wide band low noise
amplifier GaAs MMIC for terrestrial application.
To achieve wide dynamic range, the NJG1152KA1 offers
high gain mode and low gain mode. Selecting high gain mode
for weak signals, the NJG1152KA1 helps improve receiver
sensitivity through high gain and low noise figure.
Selecting low gain mode for strong signals, it bypasses LNA
circuit to offer higher linearity.
An small and ultra-thin package of FLP6-A1 is adopted.

Terrestrial application like Digital TV, Set-top box

DESCRIPTION
The RF output terminal of the LNA mode. This terminal doubles as the
drain terminal of the LNA. Please connect this terminal to the power
supply via choke inductor.
Ground terminal. This terminal should be connected to the ground
plane as close as possible for excellent RF performance.
The RF output terminal of the Bypass mode. Please connect this
terminal with RFOUT1 terminal through DC blocking capacitor shown
in the application circuit.
RF input terminal. External capacitor C1 is required to block the DC
bias voltage of internal circuit.
Ground terminal. This terminal should be connected to the ground
plane as close as possible for excellent RF performance.
Control voltage terminal. At this terminal, the switching of the LNA
mode and Bypass mode is possible.
