Pad Configuration Table 7. Pad Function Descriptions Pad No.MnemonicDescription 1 RFIN Radio Frequency Input. This pad ac couples the RF signal, has a 5 kΩ resistor connected to GND, and is matched to 50 Ω. See Figure 3 for the interface schematic. 2, 3, 4 VDD1, VDD2, VDD3 Power Supply Voltages for the Amplifier. Connect a dc bias to provide drain current (IDD). See Figure 4 for the interface schematic. 5 RFOUT RF Output. This pad ac couples the RF signal, has a 5 kΩ resistor connected to GND, and is matched to 50 Ω. See Figure 5 for the interface schematic. Die Bottom GND Ground. Die bottom must be connected to RF/dc ground. See Figure 6 for the interface schematic. INTERFACE SCHEMATICSRFOUTRFIN5kΩ 005 5kΩ 003 16709- 16709- Figure 3.
