Description

1, 2, 4, 5, 6, 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. No DC-blocking capacitor is necessary

when the RF line potential is equal to 0 V DC. See Figure 4 for the interface schematic.

8

RF1

RF Port 1. The RF1 pin is DC-coupled to 0 V. No DC-blocking capacitor is necessary when the

RF line potential is equal to 0 V DC. See Figure 4 for the interface schematic.

11

VDD

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

12

CTRL

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

14

EN

Enable Input Voltage. See Table 7 for the truth table. See Figure 5 for the interface schematic.

15

VSS

Negative Supply Voltage. See Figure 7 for the interface schematic.

18

RF2

RF Port 2. The RF2 pin is DC-coupled to 0 V. No DC-blocking capacitor is necessary 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.
