WIDE BAND LOW NOISE AMPLIFIER GaAs MMIC
! GENERAL DESCRIPTION
! PACKAGE OUTLINE
The NJG1140KA1 is a wide band low noise amplifier GaAs MMIC
designed for Set-top Boxes, TV tuners and DTV applications.
The NJG1140KA1 features broadband operation from 50MHz to
2150MHz, high linearity and high ESD tolerance. The NJG1140KA1
requires only four external components. The NJG1140KA1 is
available in a small, lead-free, halogen-free, 1.6mm x 1.6mm x 0.55
NJG1140KA1
mm, 6-pin FLP6-A1 package.

! TERMINAL INFORMATION
No. SYMBOL
DESCRIPTION
1 GND Ground terminal. Connect to the PCB ground plane.
2
NC No connected terminal. This terminal is not connected with internal
(GND) circuit. Connect to the PCB ground plane.
3
RFOUT
RF output terminal. Requires a DC blocking capacitor C2 and DC feed
inductor L1.
4 GND Ground terminal. Connect to the PCB ground plane.
5
NC No connected terminal. This terminal is not connected with internal
(GND) circuit. Connect to the PCB ground plane.
6 RFIN RF input terminal. Requires a DC bloking capacitor C1.
Notes: Ground terminal (No.1 and 4) and NC terminal (No.2 and 5) should be connected with the
PCB ground for good RF performance.
