PIU
BQ
–
(Pin 1):
Negative Baseband Input Pin of the Modulator
Q-Channel. This pin is internally biased to 1.4V, but can
also be overdriven with an external DC voltage greater than
1.4V, but less than V
CC
– 0.4V.
BQ
+
(Pin 2):
Positive Baseband Input Pin of Modulator Q-
Channel. This pin is internally biased to 1.4V, but can also
be overdriven with an external DC voltage greater than
1.4V, but less than V
CC
– 0.4V.
GC1 (Pin 3):
Gain Control Pin. This pin is the least
significant bit of the four-step modulator gain control.
MODIN (Pin 4):
Modulator Carrier Input Pin. This pin is
internally biased and should be AC-coupled. An external
matching network is required for a 50
source.
V
CC
MOD (Pin 5):
Power Supply Pin for the I/Q Modulator.
This pin should be externally connected to the other V
CC
pins and decoupled with 1000pF and 0.1
μ
F capacitors.
V
CC
RF (Pin 6):
Power Supply Pin for the I/Q Modulator
Input RF Buffer and Phase Shifter. This pin should be
externally connected to the other V
CC
pins and decoupled
with 1000pF and 0.1
μ
F capacitors.
LO1 (Pin 7):
Mixer 1st LO Input Pin. This pin is internally
biased and should be AC-coupled. An external matching
network is required for a 50
source.
V
CC
LO1 (Pin 8):
Power Supply Pin for the Mixer LO1
Circuits. This pin should be externally connected to the
other V
CC
pins and decoupled with 1000pF and 0.1
μ
F
capacitors.
DMODE (Pin 9):
Mixer 2nd LO Divider Mode Control Pin.
Low = divide-by-2, High = divide-by-1.
MX
+
(Pin 10):
Mixer Positive RF Output Pin. This pin must
be connected to V
CC
through an external matching net-
work.
MX
–
(Pin 11):
Mixer Negative RF Output Pin. This pin must
be connected to V
CC
through an external matching net-
work.
MIXEN (Pin 12):
Mixer Enable Pin. When the input voltage
is higher than V
CC
– 0.4V, the mixer circuits supplied
through pins 8, 10, 11 and 15 are enabled. When the input
voltage is less than 0.4V, these circuits are disabled.
MODEN (Pin 13):
Modulator Enable Pin. When the input
voltage is higher than V
CC
– 0.4V, the modulator circuits
supplied through pins 5, 6, 16 and 17 are enabled. When
the input voltage is less than 0.4V, these circuits are
disabled.
LO2 (Pin 14):
Mixer 2nd LO Input Pin. This pin is internally
biased and should be AC-coupled. An external matching
network is not required, but can be used for improved
matching to a 50
source.
V
CC
LO2 (Pin 15):
Power Supply Pin for the Mixer LO2
Circuits. This pin should be externally connected to the
other V
CC
pins and decoupled with 1000pF and 0.1
μ
F
capacitors.
V
CC
VGA (Pin 16):
Power Supply Pin for the Modulator
Variable Gain Amplifier. This pin should be externally
connected to the other V
CC
pins through a 47
resistor
and decoupled with a good high frequency capacitor (2pF
typical) placed close to the pin.
MODOUT (Pin 17):
Modulator RF Output Pin. This pin
must be externally biased to V
CC
through a bias choke. An
external matching network is required to match to 50
.
GC2 (Pin 18):
Gain Control Pin. This pin is the most
significant bit of the four-step modulator gain control.
BI
+
(Pin 19):
Positive Baseband Input Pin of the Modulator
I-Channel. This pin is internally biased to 1.4V, but can also
be overdriven with an external DC voltage greater than
1.4V, but less than V
CC
– 0.4V.
BI
–
(Pin 20):
Negative Baseband Input Pin of the Modula-
tor I-Channel. This pin is internally biased to 1.4V, but can
also be overdriven with an external DC voltage greater than
1.4V, but less than V
CC
– 0.4V.
GROUND (Backside Contact):
Circuit Ground Return for
the Entire IC.
