NJG1112PB1
PDC Dual Band LNA GaAs MMIC
QGENERAL DESCRIPTION
The NJG1112PB1 is a dual band low noise amplifier for
800MHz and 1500MHz band. The band switching between
800MHz CD, A Band and 1500MHz is made by 2 bit
control signal by using inverter circuit included in this IC.
The ultra small and thin FFP12-B1 is applied.

Pin Symbol
Description
1 GND Ground terminal (0V).
2
VCTL1
Control voltage input terminal. This terminal is set to 800MHz CD band or
800MHz A band to select.
3
VCTL2
Control voltage input terminal. This terminal is set to 800MHz band or
1.5GHz band to select.
4 VINV Power supply terminal of the inverter circuit.
Output terminal of 800MHz band. This terminal is also the power supply
5 RFOUT1 terminal of the LNA, please use inductor (L7) to connect power supply.
(Please see application circuit.)
6 GND Ground terminal (0V).
Output terminal of 1.5GHz band. This terminal is also the power supply
7 RFOUT2 terminal of the LNA, please use inductor (L6) to connect power supply.
(Please see application circuit.)
8 GND Ground terminal (0V).
9
RFIN3
Output terminal of 1.5GHz band. The DC blocking capacitor is not
required.
10
RFIN2
Output terminal of 800MHz A band. The DC blocking capacitor is not
required.
11 GND Ground terminal (0V).
12
RFIN1
Output terminal of 800MHz CD band. The DC blocking capacitor is not
required.
NOTE:
1) Ground terminal (1, 6, 8, 11pin) should be connected to ground plane by multiple via holes
for good grounding.
2) Please connect bypass capacitors possible close to inductors (L6, L7).
