1 RBIAS Current Mirror Bias Resistor. Use the RBIAS pin to set the quiescent current by connecting the external bias resistor as defined in Table 8. Refer to Figure 60 for the bias resistor connection. See Figure 3 for the interface schematic. 2, 5 GND Ground. The GND pin must be connected to RF and dc ground. See Figure 6 for the interface schematic. 3 RFIN RF Input. The RFIN pin is ac-coupled and matched to 50 Ω. See Figure 4 for the interface schematic. 4 RFOUT RF Output. The RFOUT pin is ac-coupled and matched to 50 Ω. See Figure 5 for the interface schematic. 6 VDD Drain Supply Voltage for the Amplifier. See Figure 5 for the interface schematic. EPAD Exposed Pad. The exposed pad must be connected to the RF and dc ground.
