Pad Function Descriptions Pad No.Mnemonic Description 1 RFIN RF Input. This pin is ac-coupled and matched to 50 Ω. 2 VDD Power Supply Voltage for the Amplifier, with Integrated RF Choke. Connect dc bias to this pad to provide drain current (IDD). 3 RFOUT RF Output. This pin is ac-coupled and matched to 50 Ω. 4 VGG2 Gate Control 2 for Amplifier. Attach bypass capacitors as shown in Figure 38. For nominal operation, apply 1.4 V to VGG2. 5 VGG1 Gate Control 1 for Amplifier. Attach bypass capacitors as shown in Figure 38. Adjust this pad to achieve IDD = 80 mA. Die Bottom GND Die bottom must be connected to RF/dc ground. Rev.
