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 Signal.
One RF input pin may be DC connected to a low impedance
ground to realize a 50Ω single-ended input at the other RF
pin. No external matching components are required. A DC
voltage should not be applied across these pins, as they
are internally connected through a transformer winding.
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 55µA for EN = 5V and 0.1µA when EN = 0V.
V
CC1
(Pin 6): Power Supply Pin for the LO Buffer Circuits.
Typical current consumption is 11mA. This pin should be
externally connected to the other V
CC
pins and decoupled
with 1µF and 0.01µF capacitors.
V
CC2
(Pin 7): Power Supply Pin for the Bias Circuits.
Typical current consumption is 2.5mA. This pin should be
externally connected to the other V
CC
pins and decoupled
with 1µF and 0.01µF capacitors.
GND (Pins 9, 12): Ground. These pins are internally
connected to the Exposed Pad for better isolation. They
should be connected to ground on the circuit board,
though they are not intended to replace the primary
grounding through the Exposed Pad of the package.
IF
–
and 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. The LO input is internally matched to
50Ω. The LO can be driven with a single-ended source
through either LO input pin, with the other LO input pin
connected to ground. There is an internal DC resistance
across these pins of approximately 480Ω. Thus, a DC
blocking capacitor should be used if the signal source has
a DC voltage present.
Exposed Pad (Pin 17): Circuit Ground Return for the
Entire IC. This must be soldered to the printed circuit board
ground plane.
