TRANSMITTING POWER AMPLIFIER
GaAs MMIC
nGENERAL DESCRIPTION
NJG1309VB2 is a positive voltage supply type GaAs power
amplifier MMIC designed for Digital Cordless Phone.
Gate bias and Gain control bias terminals are supplied
by positive voltage.
These terminals have high-impedance characteristics.
NJG1309VB2 can reduce power
consumption at receiving mode by “Standby Function”.

nTERMINAL INFORMATION
TERMINAL INFORMATION
PIN No. SYMBOL
DESCRIPTIONS
The output voltage of DC/DC converter is toggled ON/OFF by changing voltage to
1 VSTB this terminal to High/Low.
The positive voltage of this terminal is supplied to op-amp 1 in the DC/DC
2
+VGG
converter, and its output voltage (negative) is internally supplied to the gate ports
of #1 to 3 amplifiers. The current of amplifier is controlled by the voltage of this
terminal.
3
-VGG1
The voltage of the gate ports of #1 to 3 amplifier are supplied through this
terminal. Please place a capacitor at this terminal as close as possible.
4 GND Ground terminal(0V)
5
RFin
This terminal is a signal input terminal connected to input port of amplifier through
matching circuit and DC blocking capacitor.
6 GND Ground terminal(0V)
7 GND Ground terminal(0V)
This terminal is Connected to gate fourth stage amplifier. Please connect with -
8 -VGG2 VGG2 terminal on PCB board and place a bypass possible , since this terminal is
NOT connected with op-amp input.
9 GND Ground terminal(0V)
10 GND Ground terminal(0V)
This terminal is a signal output terminal connected to the output port of amplifier
11 RFout through matching circuit and DC blocking capacitor.
12 GND Ground terminal(0V)
13
VDD3
This terminal is connected to drain port of fourth stage amplifier. Please place a
choke inducter and a bypass capacitor shown in the application circuit below.
14 GND Ground terminal(0V)
15
VDD2
The voltage of the gate ports of #1 to 3 amplifier are supplied through this
terminal. Please place a capacitor at this terminal as close as possible.
16 GND Ground terminal(0V)
17 GND Ground terminal(0V)
This terminal is a gain control terminal of amplifier, and also internally connected
18 -VCONT to output port of op-amp2. Please place a bypass capacitor at this terminal shown
in the application circuit below as close as possible.
The positive voltage of this terminal is supplied to op-amp2 in the DC/Dc
19
+VCONT
converter, and its output voltage(negative) is internally supplied to the gain
control port of amplifier. The gain of amplifier is controlled by the voltage of this
terminal.
This terminal is a voltage supply terminal of DC/DC converter. Please place
20 VDD1 bypass capacitor shown in the application circuit below as close as possible.
NOTE 1) The ground terminal(4,6,7,9,10,12,14,16,17)shond be directly connected to ground plane
To minimize fringing inductance.

Notes
[1] CMOS IC negative voltage generator has Internal CR oscillator, therefor to reduction of noise,
decoupling capacitor(C12) should be connected between the 20pin and the GND.
[2] Chip parts as follows should be connected to the leads of IC as near as possible.
(1) 3pin - C1
(2) 8pin - C2
(3) 13pin - L1
(4) 15pin - C3
