FUNCTION
Main Channel RF input. Internally matched to 50 Ω . Requires an input DC-blocking
capacitor.
Main Channel Balun Center Tap. Bypass to GND with 39pF and 0.033μF capacitors as
close as possible to the pin with the smaller value capacitor closer to the part.
Ground
Power Supply. Bypass to GND with 0.01μF capacitors as close as possible to the pin. Pins
4 and 6 do not require bypass capacitors.
Diversity Channel Balun Center Tap. Bypass to GND with 39pF and 0.033μF capacitors as
close as possible to the pin with the smaller value capacitor closer to the part.
Diversity Channel RF Input. Internally matched to 50 Ω . Requires an input DC-blocking
capacitor.
IF Diversity Amplifier Bias Control. Connect a resistor from this pin to ground to set the bias
current for the diversity IF amplifier (see the Typical Operating Characteristics for typical
performance vs. resistor value).
Diversity Mixer Differential IF Outputs. Connect pullup inductors from each of these pins to
V CC (see the Typical Application Circuit ).
Diversity External Inductor Connection. Connect a parallel combination of an inductor and
a 500 Ω resistor from this pin to ground to increase the RF-to-IF and LO-to-IF isolation (see
the Typical Operating Characteristics for typical performance vs. inductor value).
LO Diversity Amplifier Bias Control. Connect a resistor from this pin to ground to set the
bias current for the diversity LO amplifier (see the Typical Operating Characteristics for
typical performance vs. resistor value).
No Connection. Not internally connected.
Local Oscillator 1 Input. This input is internally matched to 50 Ω . Requires an input DC-
blocking capacitor.
Local Oscillator Select. Set this pin to high to select LO1. Set to low to select LO2.
Local Oscillator 2 Input. This input is internally matched to 50 Ω . Requires an input DC-
blocking capacitor.
LO Main Amplifier Bias Control. Connect a resistor from this pin to ground to set the bias
current for the main LO amplifier (see the Typical Operating Characteristics for typical
performance vs. resistor value).
Main External Inductor Connection. Connect a parallel combination of an inductor and a
500 Ω resistor from this pin to ground to increase the RF-to-IF and LO-to-IF isolation (see
Typical Operating Characteristics for typical performance vs. inductor value).
Main Mixer Differential IF Outputs. Connect pullup inductors from each of these pins to V CC
(see the Typical Application Circuit ).
IF Main Amplifier Bias Control. Connect a resistor from this pin to ground to set the bias
current for the main IF amplifier (see the Typical Operating Characteristics for typical
performance vs. resistor value).
Exposed Pad. Internally connected to GND. Connect to a large ground plane using
multiple vias to maximize thermal and RF performance.
