Pin Descriptions

Pin

Name

Function

1, 15, 18

GND

This pin is internally connected to the exposed paddle. Connect this pin to ground as close as possible to

the pin.

2, 4, 5, 6, 7,

9, 10, 11, 12,

14, 19

GND

Connect this pin directly to ground as close as possible to the pin with thru vias.

3

RF1

RF1 Port. If this pin is not 0V DC, then an external coupling capacitor must be used.

8

RFC

RF Common Port. If this pin is not 0V DC, then an external coupling capacitor must be used.

13

RF2

RF2 Port. If this pin is not 0V DC, then an external coupling capacitor must be used.

16

C2

Logic control pin. See Table 7 for proper logic setting.

17

C1

Logic control pin. See Table 7 for proper logic setting.

20

Power supply. Bypass to GND with capacitors shown in the Figure 30 as close as possible to the pin.

EP

Exposed Pad. This is 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.
