GND

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

6

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. See Table 6 for the truth table and Figure 5 for the interface schematic.

9, 13

VSS

Negative Supply Voltage.

10, 12

LS

Logic Select. See Table 6 for the truth table and Figure 7 for the control interface schematic.

11

VDD

Positive Supply Voltage.

16

RF4

RF Throw Port 4. The RF4 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. See Table 6 for the truth table and Figure 5 for the interface schematic.

20

RF3

RF Throw Port 3. The RF3 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. See Table 6 for the truth table and Figure 5 for the interface schematic.

25

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. See Table 6 for the truth table and Figure 5 for the interface schematic.

29

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. See Table 6 for the truth table and Figure 5 for the interface schematic.

Carrier Bottom

The carrier bottom must be connected to ground for proper operation
