GND

Ground. Bonding of these GND pads is optional. See the Applications Information section.

14

RFC

RF Common Port. The RFC pad 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. For the interface schematic, see Figure 5.

2

RF1

RF Throw Port 1. The RF1 pad 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. For the interface schematic, see Figure 5.

5

VDD

Positive Supply Voltage. For the interface schematic, see Figure 6.

6

CTRL

Control Input Voltage. For the interface schematic, see Figure 8.

7

EN

Enable Input Voltage. For the interface schematic, see Figure 9.

8

VSS

Negative Supply Voltage. For the interface schematic, see Figure 7.

11

RF2

RF Throw Port 2. The RF2 pad 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. For the interface schematic, see Figure 5.

Carrier Bottom

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