Pin No. Mnemonic Description
1, 3, 4, 6, 7, 9 GND Ground. These pins and package bottoms connect to RF/dc ground.
2 LO Local Oscillator Port. This pin is ac-coupled and matched to 50 Ω.
5 IF
Intermediate Frequency Port. This pin is dc-coupled. For applications, not requiring operation to dc, dc
block this port externally using a series capacitor of a value chosen to pass the necessary IF frequency
range. For operation to dc, this pin must not source or sink more than 3 mA of current or die malfunction
and possible die failure may result. See Figure 5 for the interface schematic.
8 RF Radio Frequency Port. This pin is ac-coupled and matched to 50 Ω.
10 to 12 NIC Not Internally Connected. These pins can be connected to RF/dc ground. Device performance is not affected.
EPAD Exposed Pad. The exposed pad must be connected to RF/dc ground.
