GND

Ground. These pins must be connected to the RF/dc ground of the PCB.

2

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 5 for the interface schematic.

5

RF1

RF Port 1. 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 5 for the interface schematic.

7

VDD

Positive Supply Voltage.

8

CTRL

Control Input Voltage. See Figure 6 for the interface schematic.

9

VSS

Negative Supply Voltage.

11

RF2

RF Port 2. 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 5 for the interface schematic.

EPAD

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