GND

Ground. These pins must be connected to the RF/dc ground of the printed circuit board (PCB).

2

RF5

RF Throw Port 5. This pin is dc coupled and no dc blocking capacitor is necessary when the RF line potential

is within 0 V dc.

5

RF4

RF Throw Port 4. This pin is dc coupled and no dc blocking capacitor is necessary when the RF line potential

is within 0 V dc.

8

RF3

RF Throw Port 3. This pin is dc coupled and no dc blocking capacitor is necessary when the RF line potential

is within 0 V dc.

11

RF2

RF Throw Port 2. This pin is dc coupled and no dc blocking capacitor is necessary when the RF line potential

is within 0 V dc.

14

RF1

RF Throw Port 1. This pin is dc coupled and no dc blocking capacitor is necessary when the RF line potential

is within 0 V dc.

16

VDD

Positive Supply Voltage.

17

V1

Digital Input Voltage Applied to the Least Significant Bit (LSB) of Digital Interface for Controlling RF Path

State. See Table 5.

18

V2

Digital Input Voltage Applied to the Second Bit of Digital Interface for Controlling RF Path State. See Table 5.

19

V3

Digital Input Voltage Applied to the Most Significant Bit (MSB) of Digital Interface for Controlling RF Path

State. See Table 5.

20

VSS

Optional Negative Supply Voltage. This pin can be connected to ground to operate with the internal

negative voltage generator. The internal negative voltage generator is disabled when this pin is connected

to an external 3.3 V supply.

22

RFC

RF Common Port. This pin is dc-coupled and no dc blocking capacitor is necessary when the RF line

potential is within 0 V dc.

EPAD

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