Ground
Power Supply. Connect bypass capacitors as close to the pin as possible (see the Typical
Application Circuit).
IF Diversity Amplifier Bias Control. Connect a 1.2kΩ 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
(see the Typical Application Circuit).
LO Diversity Amplifier Bias Control. Connect a 392Ω 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 50Ω. Requires an input DC-blocking
capacitor.
Main Channel RF Input. Internally matched to 50Ω. Requires an input DC-blocking capacitor.
Main Channel Balun Center Tap. Connect a 0.033µF capacitor from this pin to the board ground.
Diversity Channel Balun Center Tap. Connect a 0.033µF capacitor from this pin to the ground.
Diversity Channel RF Input. Internally matched to 50Ω. Requires an input DC-blocking capacitor.
Local Oscillator Select. Set this pin to high to select LO1. Set to low to select LO2.
