GND

Ground. These pins must be connected to the RF/dc ground of the printed circuit board (PCB).

3

RFC

RF Common Port. This pin is dc-coupled to 0 V and ac matched to 50 Ω. No dc blocking capacitor is

necessary when the RF line potential is equal to 0 V dc. See Figure 6 for the interface schematic.

8

RF1

RF1 Port. This pin is dc-coupled to 0 V and ac matched to 50 Ω. No dc blocking capacitor is necessary

when the RF line potential is equal to 0 V dc. See Figure 6 for the interface schematic.

11

VDD

Positive Supply Voltage.

12

CTRL

Control Input. See Figure 7 for the interface schematic.

14

EN

Enable Input. See Figure 7 for the interface schematic.

15

VSS

Negative Supply Voltage.

18

RF2

RF2 Port. This pin is dc-coupled to 0 V and ac matched to 50 Ω. No dc blocking capacitor is necessary

when the RF line potential is equal to 0 V dc. See Figure 6 for the interface schematic.

EPAD

Exposed Pad. The exposed pad must be connected to the RF/dc ground of the PCB.
