Pin Configuration Table 3. Pin Function Descriptions Pin No.Mnemonic Description 1 RFIN Radio Frequency Input. This pad is matched to 50 Ω. See Figure 3 for the interface schematic. 2, 3 VDD1, VDD2 Power Supply Voltages. Power supply voltage for the amplifier. See Figure 24 and Figure 25 for required external components. See Figure 4 for the interface schematic. 4 RFOUT Radio Frequency Output. This pad is matched to 50 Ω. See Figure 5 for the interface schematic. 5, 6 VGG2, VGG1 Gate Control Voltages. Optional gate control for amplifier. When left open, the amplifier is self biased. Applying a negative voltage reduces the current. See Figure 6 for the interface schematic. Die Bottom GND Ground. Die bottom must be connected to RF/dc ground. See Figure 7 for the interface schematic. INTERFACE SCHEMATICSRFIN 003 ESD 14481- 006 VGG1, VGG2 14481- Figure 3. RFIN Interface Schematic Figure 6.
