1 RFIN Radio Frequency (RF) Input. This pad is ac-coupled, but has a large resistor to GND for ESD protection, and matched to 50 Ω. See Figure 3 for the interface schematic. 2 VGG2 Gain Control. This pad is dc-coupled and accomplishes gain control by bringing this voltage lower and becoming more negative. See Figure 4 for the interface schematic. 3 VDD Power Supply Voltage for the Amplifier. Connect a dc bias to provide drain current (IDD). See Figure 5 for the interface schematic. 4 RFOUT RF Output. This pad is ac-coupled, but has a large resistor to GND for ESD protection, and matched to 50 Ω. See Figure 6 for the interface schematic. Die Bottom GND Die bottom must be connected to RF/dc ground. See Figure 7 for the interface schematic.
