FUNCTION
Main Channel RF Input. This input is internally matched to 50 ? and is DC shorted to ground
through a balun.
Main RF Balun Center Tap. Connect bypass capacitors from this pin to ground.
Bias control for the Main Mixer. Connect a 267 ? resistor from this pin to ground to set the bias
current for the main mixer.
Ground
Bias Control for the Diversity Mixer. Connect a 267 ? resistor from this pin to ground to set the bias
current for the diversity mixer.
Diversity RF Balun Center Tap. Connect bypass capacitors from this pin to ground.
Diversity Channel RF Input. This input is internally matched to 50 ? and is DC shorted to ground
through a balun.
Power-Supply Connections. Connect bypass capacitors as shown in the Typical Application
Circuit .
Differential IF Output for Diversity Mixer. Connect 560nH pullup inductors and 137 ? pullup
resistors from each of these pins to V CC for a 70MHz to 100MHz IF range.
Local Oscillator Input 1. This input is internally matched to 50 ? and is DC shorted to ground
through a balun.
Local Oscillator Select. Set this pin to logic HIGH to select LO1; set to logic LOW to select LO2.
Local Oscillator Input 2. This input is internally matched to 50 ? and is DC shorted to ground
through a balun.
Differential IF Output for the Main Mixer. Connect 560nH pullup inductors and 137 ? pullup
resistors from each of these pins to V CC for a 70MHz to 100MHz IF range.
