20

GND

Ground. These pins must be connected to the RF/DC ground of the PCB.

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.

9

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.

12

CTRL

Control Input. For the truth table, see Table 7.

13

VDD

Positive Supply Voltage.

14

VSS

Negative Supply Voltage.

17

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.

EPAD

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