See Table 7 for logic control states. CTL RF common port. Matched to 50 in the insertion loss state only. If this pin is not 0V DC, then an external 2 RFC coupling capacitor must be used. 3 V Power supply. Bypass to GND with capacitors as close as possible to the pin. CC RF2 port. Matched to 50 in the insertion loss state only. If this pin is not 0V DC, then an external coupling 4 RF2 capacitor must be used. 5 GND Ground. Ground this pin as close to the device as possible. RF1 port. Matched to 50 in the insertion loss state only. If this pin is not 0V DC, then an external coupling 6 RF1 capacitor must be used. Exposed pad. Internally connected to GND. Solder this exposed pad to a PCB pad that uses multiple EP 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. 2017 Integrated Device Technology, Inc. 2 Rev O August 8, 2017
