Pad Configuration Table 5. Pad Function Descriptions Pad No.MnemonicDescription 1 RFIN RF Input. This pad is ac-coupled and matched to 50 Ω. See Figure 3 for the interface schematic. 2 VGG1A Gate Control Pad for Alternate Bias Configuration. See Figure 4 for the interface schematic.. 3 to 6 VDD1A to VDD4A Drain Bias Voltage Pads for the Amplifier. External bypass capacitors of 100 pF and 0.1 μF are required. See Figure 5 for the interface schematic. 7 RFOUT RF Output. This pad is ac-coupled and matched to 50 Ω. See Figure 6 for the interface schematic. 8 to 11 VDD4B to VDD1B Drain Bias Voltage Pads for Alternate Bias Configuration. External bypass capacitors of 100 pF and 0.1 μF are required for decoupling. See Figure 7 for the interface schematic. 12 VGG1B Gate Control Pad for the Amplifier. External bypass capacitors of 100 pF and 0.1 μF are required. See Figure 8 for the interface schematic. Die Bottom GND Die bottom must be connected to RF/dc ground. See Figure 9 for the interface schematic. INTERFACE SCHEMATICS 3 V 00 DD1B TO VDD4BRFIN 32 1 143- 3- 13 14 13 Figure 3.
