PIU
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.
These pins must be driven with a differential signal. Each
pin must also be connected to a DC ground capable of
sinking 7.5mA (15mA 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 50
(or 75
).
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 55
μ
A for EN = 5V and 0.01
μ
A 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 100pF and 0.01
μ
F 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 100pF and 0.01
μ
F 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
50
; however, external DC blocking capacitors are re-
quired because these pins are internally biased to approxi-
mately 1.7V DC. Either LO input can be driven with a
single-ended source while connecting the unused input to
ground through a DC blocking capacitor.
Exposed Pad (Pin 17):
Circuit Ground Return for the
Entire IC. This must be soldered to the printed circuit board
ground plane.
