FUNCTION
Main Channel RF input. Internally matched to 50 ? . Requires an input DC-blocking capacitor.
Main Channel Balun Center Tap. Bypass to GND with capacitors close to the pin.
Ground
Power Supply. Connect bypass capacitors as close to the pin as possible (see the Typical
Application Circuit ).
Diversity Channel Balun Center Tap. Bypass to GND with capacitors close to the pin.
Diversity Channel RF Input. Internally matched to 50 ? . Requires an input DC-blocking capacitor.
IF Diversity Amplifier Bias Control. Connect a 1.07k ? resistor from this pin to ground to set the bias
current for the diversity IF amplifier (see the Typical Operating Characteristics for typical performance
versus resistor value).
Diversity Mixer Differential IF Output. Connect pullup inductors from each of these pins to V CC (see
the Typical Application Circuit ).
Connect a 30nH inductor from this pin to ground to increase the RF-to-IF and LO-to-IF isolation.
Connect this pin to ground if isolations can be degraded (see the Typical Operating Characteristics
for typical degradation).
LO Diversity Amplifier Bias Control. Connect a 1.1k ? resistor from this pin to ground to set the bias
current for the diversity LO amplifier (see the Typical Operating Characteristics for typical
performance versus resistor value).
No Connection. Not internally connected.
Local Oscillator 1 Input. This input is internally matched to 50 ? . Requires an input DC-blocking capacitor.
Local Oscillator Select. Set this pin to high to select LO1. Set low to select LO2.
Local Oscillator 2 Input. This input is internally matched to 50 ? . Requires an input DC-blocking capacitor.
LO Main Amplifier Bias Control. Connect a 1.1k ? resistor from this pin to ground to set the bias
current for the main LO amplifier (see the Typical Operating Characteristics for typical performance
versus resistor value).
Connect a 30nH inductor from this pin to ground to increase the RF-IF and LO-IF isolation. Connect
this pin to ground if isolations can be degraded (see the Typical Operating Characteristics for typical
degradation).
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 1.07k ? 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 Paddle. Solder the exposed paddle to the ground plane using multiple vias. This paddle
affects RF performance and provides heat dissipation.
