Description

1, 2, 4 to 7, 9, 10, 13, 16, 17, 19, 20

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. For the interface schematic, see Figure 5.

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. for the interface schematic, see Figure 5.

11

VDD

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

12

CTRL

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

14

EN

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

15

VSS

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

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. For the interface schematic, see Figure 5.

EPAD

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