GND Ground. The package bottom has an exposed metal pad that must connect to the printed circuit
board (PCB) RF/dc ground. See Figure 6 for the GND interface schematic.
3 RFC RF Common Port. This pin is dc-coupled and matched to 50 Ω. A dc blocking capacitor is required
if the RF line potential is not equal to 0 V dc.
8 RF4 RF4 Port. This pin is dc-coupled and matched to 50 Ω. A dc blocking capacitor is required if the RF
line potential is not equal to 0 V dc.
11 RF3 RF3 Port. This pin is dc-coupled and matched to 50 Ω. A dc blocking capacitor is required if the RF
line potential is not equal to 0 V dc.

20 RF2 RF2 Port. This pin is dc-coupled and matched to 50 Ω. A dc blocking capacitor is required if the RF
line potential is not equal to 0 V dc.
23 RF1 RF1 Port. This pin is dc-coupled and matched to 50 Ω. A dc blocking capacitor is required if the RF
line potential is not equal to 0 V dc.
EPAD Exposed Pad. The exposed pad must be connected to the RF/dc ground of the PCB.
