pin FuncTions
GND (Pins 1, 4, 6, 10, 12, Exposed Pad Pin 13): Ground.
These pins must be soldered to the RF ground on the circuit
board. The exposed pad metal of the package provides
both electrical contact to ground and good thermal contact
to the printed circuit board.
IF
+
, IF
–
(Pins 2, 3): Differential Terminals for the IF. These
pins may be used for a differential IF or connected to an
external balun if a single-ended IF port is needed. The IF
port can be used from DC up to 6GHz depending on the
external balun bandwidth.
RF (Pin 5): Single-Ended Terminal for the RF Port. This
pin is internally connected to the primary side of the RF
transformer, which has low DC resistance to ground. A
series DC blocking capacitor must be used to avoid damage
to the integrated transformer if DC voltage is present. The
RF port is impedance matched from 2GHz to 14GHz as
long as the LO is driven with a 0 ±6dBm source between
1GHz and 12GHz.
EN (Pin 7): Enable Pin. When the voltage applied to this
pin is greater than 1.2V, the mixer is enabled. When the
voltage is less than 0.3V, the mixer is disabled. Typical
input current
is less than 30μA. This pin has an internal
376kΩ pull-down resistor.
X2 (Pin 8): Digital Control Pin for LO Frequency Doubler.
When the voltage applied to this pin is greater than 1.2V,
the LO frequency doubler is enabled. When the voltage DC
is less than 0.3V, the LO frequency doubler is disabled.
Typical input current is less than 30μA. This pin has an
internal 376kΩ pull-down resistor.
V
CC
(Pin 9): Power Supply Pin. This pin must be externally
connected to a regulated 3.3V supply, with a bypass capaci-
tor located
close to the pin. Typical current consumption
is 120mA when the part is enabled.
LO
(Pin 11): Input for the Local Oscillator (LO). A series
DC blocking capacitor must be used. Typical DC voltage
at this pin is 1.6V.
