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 capacitors shown in the Typical Application Circuit as close as
possible to the pin.
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.
Diversity Mixer Differential IF Output. Connect pullup inductors from each of these pins to V CC (see the
Typical Application Circuit ).
Diversity External Inductor Connection. Connect this pin to ground. For improved RF-to-IF and
LO-to-IF isolation, connect a low-ESR 10nH inductor from this pin to ground (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.
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.
Main External Inductor Connection. Connect this pin to ground. For improved RF-to-IF and LO-to-IF
isolation, connect a low-ESR 10nH inductor from this pin to ground (see the Typical Operating
Characteristics for typical performance vs. Inductor value).
Main Mixer Differential IF Output. 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.
Exposed Pad. Internally connected to GND. Solder this exposed pad to a PCB pad that uses multiple
ground vias to provide heat transfer out of the device into the PCB ground planes. These multiple via
grounds are also required to achieve the noted RF performance.
