BLOCK DIAGRA
W
NC (Pins 1, 4, 8, 13, 16): Not connected internally. These
pins should be grounded on the circuit board for improved
LO to RF and LO to IF isolation.
RF
+
, RF
–
(Pins 2, 3): Differential Inputs for the RF Sig-
nal. These pins must be driven with a differential signal.
Each pin must be connected to a DC ground capable of
sinking 15mA (30mA total). This DC bias return can be
accomplished through the center-tap of a balun, or with
shunt inductors. An impedance transformation is required
to match the RF input to 50Ω (or 75Ω).
EN (Pin 5): Enable Pin. When the input voltage is higher
than 3V, the mixer circuits supplied through Pins 6, 7, 10,
and 11 are enabled. When the input voltage is less than
0.3V, all circuits are disabled. Typical enable pin input
current is 50μA for EN = 5V and 0μA when EN = 0V.
V
CC1
(Pin 6): Power Supply Pin for the LO Buffer Circuits.
Typical current consumption is 22mA. This pin should be
externally connected to the other V
CC
pins, and decoupled
with 0.01μF and 1μF capacitors.
V
CC2
(Pin 7): Power Supply Pin for the Bias Circuits.
Typical current consumption is 4mA. This pin should be
externally connected to the other V
CC
pins, and decoupled
with 0.01μF and 1μF capacitors.
GND (Pins 9 and 12): Ground. These pins are internally
connected to the backside ground for better isolation. They
should be connected to RF ground on the circuit board,
although they are not intended to replace the primary
grounding through the backside contact of the package.
IF
–
, IF
+
(Pins 10, 11): Differential Outputs for the IF
Signal. An impedance transformation may be required to
match the outputs. These pins must be connected to V
CC
through impedance matching inductors, RF chokes or a
transformer center-tap.
LO
–
, LO
+
(Pins 14, 15): Differential Inputs for the Local
Oscillator Signal. They can also be driven single-ended by
connecting one to an RF ground through a DC blocking
capacitor. These pins are internally biased to 2V; thus, DC
blocking capacitors are required. An impedance transfor-
mation or matching resistor is required to match the LO
input to 50Ω (or 75Ω).
GROUND (Pin 17): (Backside Contact): Circuit Ground
Return for the Entire IC. This must be soldered to the
printed circuit board ground plane.
