PIN
NAME
FUNCTION
1
RFMAIN
Main Channel RF Input. This input is internally matched to 50
and is DC shorted to ground
through a balun.
2
TAPMAIN
Main RF Balun Center Tap. Connect bypass capacitors from this pin to ground.
3
MAINBIAS
Bias control for the Main Mixer. Connect a 267
resistor from this pin to ground to set the bias
current for the main mixer.
4, 5, 6, 11,
12, 15, 17,
18, 20, 22,
24, 25, 26,
28, 29, 31,
34, 35, EP
GND
Ground
7
DIVBIAS
Bias Control for the Diversity Mixer. Connect a 267
resistor from this pin to ground to set the bias
current for the diversity mixer.
8
TAPDIV
Diversity RF Balun Center Tap. Connect bypass capacitors from this pin to ground.
9
RFDIV
Diversity Channel RF Input. This input is internally matched to 50
and is DC shorted to ground
through a balun.
10, 16, 21,

VCC
Power-Supply Connections. Connect bypass capacitors as shown in the Typical Application
Circuit.
13, 14
IFDIV+, IFDIV-
Differential IF Output for Diversity Mixer. Connect 560nH pullup inductors and 137
pullup
resistors from each of these pins to VCC for a 70MHz to 100MHz IF range.
19
LO1
Local Oscillator Input 1. This input is internally matched to 50
and is DC shorted to ground
through a balun.
23
LOSEL
Local Oscillator Select. Set this pin to logic HIGH to select LO1; set to logic LOW to select LO2.
27
LO2
Local Oscillator Input 2. This input is internally matched to 50
and is DC shorted to ground
through a balun.
32, 33
IFMAIN-,
IFMAIN+
Differential IF Output for the Main Mixer. Connect 560nH pullup inductors and 137
pullup
resistors from each of these pins to VCC for a 70MHz to 100MHz IF range.
