Pad Configuration Table 3. Pad Function Descriptions Pad No.FunctionDescription 1 RFIN RF Input. This pad is dc-coupled and matched to 50 Ω. 2 VDD Power Supply Voltage for the Amplifier. External bypass capacitors are required. 3 ACG1 Low Frequency Termination. Attach an external bypass capacitor (see Figure 34). 4 RFOUT/VDD RF Output/Alternate Power Supply Voltage for the Amplifier. An external bias tee is required when using Pin 4 as an alternative VDD. This pad is dc-coupled and matched to 50 Ω. 5, 6 ACG2, ACG3 Low Frequency Terminations. Attach external bypass capacitors (see Figure 34). 7 VGG Gate Control for Amplifier. Adjust to achieve IDD = 70 mA. Die Bottom GND Ground. Die bottom must be connected to RF/dc ground. Rev.
