1 V
STB
The output voltage of DC/DC converter is toggled ON/OFF by changing voltage to
this terminal to High/Low.
2 +V
GG
The positive voltage of this terminal is supplied to op-amp 1 in the DC/DC
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 -V
GG1
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 RF
in
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)
8 -V
GG2
This terminal is Connected to gate fourth stage amplifier. Please connect with V
GG2
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)
11 RF
out
This terminal is a signal output terminal connected to the output port of amplifier
through matching circuit and DC blocking capacitor.
12 GND Ground terminal(0V)
13 V
DD3
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 V
DD2
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)
18 -V
CONT
This terminal is a gain control terminal of amplifier, and also internally connected
to output port of op-amp2. Please place a bypass capacitor at this terminal shown
in the application circuit below as close as possible.
19 +V
CONT
The positive voltage of this terminal is supplied to op-amp2 in the DC/Dc
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.
20 V
DD1
This terminal is a voltage supply terminal of DC/DC converter. Please place
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.
