GND

Ground. The GND pins must be connected to the RF and dc ground of the PCB.

3

RFC

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

required when the RF line potential is equal to 0 V dc. See Figure 3 for the interface schematic.

8

RF1

RF Throw Port 1. The RF1 pin is dc-coupled to 0 V and ac matched to 50 Ω. No dc blocking capacitor

is required when the RF line potential is equal to 0 V dc. See Figure 3 for the interface schematic.

12

VDD

Positive Supply Voltage Input. See Figure 5 for the interface schematic.

14

CTRL

Control Voltage Input. See Figure 4 for the interface schematic.

18

RF2

RF Throw Port 2. The RF2 pin is dc-coupled to 0 V and ac matched to 50 Ω. No dc blocking capacitor

is required when the RF line potential is equal to 0 V dc. See Figure 3 for the interface schematic.

EPAD

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