Description

1, 2, 4 to 6, 8, 9, 17, 19, 20, 22 GND

Ground.

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.

7

RF4

RF Throw Port 4. The RF4 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.

10

RF3

RF Throw Port 3. The RF3 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

TEST

Factory Test Pin. The TEST pin must be tied to ground.

13

LS

Logic Select. See Table 6.

14

V2

Control Input 2. See Table 6.

15

V1

Control Input 1. See Table 6.

16

VDD

Positive Supply Voltage.

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.

21

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.

EPAD

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