Pin Descriptions

Pin

Name

Function

1

Logic control pin. See Table 3 for logic control states.

2

RFC

RF common port. Matched to 50Ω in the insertion loss state only. If this pin is not 0V DC, then an

external coupling capacitor must be used.

3

Power supply. Bypass to GND with capacitors as close as possible to the pin.

4

RF2

RF2 port. Matched to 50Ω in the insertion loss state only. If this pin is not 0V DC, then an external

coupling capacitor must be used.

5

GND

Ground. Ground this pin as close to the device as possible.

6

RF1

RF1 port. Matched to 50Ω in the insertion loss state only. If this pin is not 0V DC, then an external

coupling capacitor must be used.

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.
