GND

Ground these pins as close to the device as possible.

3

RF1

RF1 Port. Matched to 75 ohms. If this pin is not 0V DC, then an external coupling capacitor must be

used.

8

RFC

RFC Port. Matched to 75 ohms. If this pin is not 0V DC, then an external coupling capacitor must be

used.

13

RF2

RF2 Port. Matched to 75 ohms. If this pin is not 0V DC, then an external coupling capacitor must be

used.

16

C2

Control pin to set switch state. See Table 8.

17

C1

Control pin to set switch state. See Table 8.

20

Power Supply. Bypass to GND with capacitors shown in the Typical Application Circuit as close as

possible to pin.

EP

Exposed Pad. Internally connected to GND. Solder this exposed pad to a PCB pad that uses multiple

ground vias to provide heat transfer out of the device into the PCB ground planes. These multiple ground

vias are also required to achieve the specified RF performance.
