Description

1, 2, 4 to 7, 9 to 11, 13, 15 to 17, 19, 20

GND

Ground. These pins must be connected to the RF and DC ground of the PCB. See Figure 6 for the

interface schematic.

3

RFC

RF Common Port. This 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 4 for the interface

schematic.

8

RF1

RF Throw Port 1. This 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 4 for the interface

schematic.

12

VDD

Positive Supply Voltage Input. See Figure 6 for the interface schematic.

14

CTRL

Control Voltage Input. See Figure 5 for the interface schematic.

18

RF2

RF Throw Port 2. This 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 4 for the interface

schematic.

EPAD

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