pin FuncTions
TP (Pin 1): Test Point. It is used for manufacture measure-
ment only. It is recommended to be connected to ground.
RF
(Pin 2): Single-Ended Input for the RF Signal. This pin
is internally connected to the primary side of the RF input
transformer, which has low DC resistance to ground. A
series DC-blocking capacitor should be used to avoid
damage to the integrated transformer when DC voltage
is present at the RF input. The RF input impedance is
matched under the condition that the LO input is driven
with a 0dBm ±6dB source between 0.2GHz and 3.5GHz.
CT (Pin 3): RF Transformer Secondary Center-Tap. This
pin must be connected to ground with minimum parasitic
resistance and inductance to complete the Mixer’s DC
current path. Typical DC current is 80mA with LO disabled
and 134mA when LO signal is applied.
GND (Pins 4, 9, 11, 13, Exposed Pad Pin 17): Ground.
These pins must be soldered to the RF ground plane 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.
EN (Pin 5): Enable Pin. When the input voltage is greater
than 1.2V, the mixer
is enabled. When the input voltage is
less
than 0.3V or left open, the mixer is disabled. Typical
input current is less than 30μA. This pin has an internal
pull-down resistor.
V
CC
(Pins 6, 7): Power Supply Pins. These pins are in-
ternally connected
and must be externally connected to
block DiagraM
a regulated 2.5V to 3.6V supply, with bypass capacitors
located close to the pin. Typical current consumption is
70mA through these pins.
ISEL (Pin 8): Low Power Select Pin. When this pin is pulled
low (<0.3V) or left open, the mixer is biased at the normal
current level for best RF performance. When greater than
1.2V is applied, the mixer operates at reduced current mode,
which provides reasonable performance at lower power
consumption. This pin has an internal pull-down resistor.
LO (Pin 10): Single-Ended Input for the Local Oscillator.
This pin is internally connected to the primary side of the
RF input transformer, which has low DC resistance to
ground. A series DC blocking capacitor should be used
to avoid damage to the integrated transformer when DC
voltage is present at the LO input.
TEMP (Pin 12): Temperature Sensing Diode. This pin is
connected to the anode of a diode that may be used to
measure the die temperature, by forcing a current and
measuring the voltage.
IF
–
(Pin 14) and IF
+
(Pin 15): Open-Collector Differential
Outputs for the IF Amplifier. These pins must be connected
to a DC supply through impedance matching inductors, or
a transformer center-tap.
Typical DC current consumption
is 67mA into each pin.
IFBIAS (Pin 16): This Pin Allows Adjustment of the IF
Amplifier Current. Typical DC voltage is 2.1V. This pin
should be left floating for optimum performance.
