1, 2, 8, 9, 10, NIC No Internal Connection. Note that data shown herein was measured with these pins externally connected 11, 12, 16 to RF/dc ground. See Figure 3 for the interface schematic. 3 VDD Power Supply Voltage for the Amplifier. Connect a dc bias to provide drain current (IDD). See Figure 4 for the interface schematic. 4 VGG2 Gain Control. This pin is dc-coupled and accomplishes gain control by reducing the internal voltage and becoming more negative. See Figure 5 for the interface schematic. 5, 7, 13, 15 GND These pins must be connected to RF/dc ground. See Figure 3 for the interface schematic. 6 RFIN Radio Frequency (RF) Input. This pin 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. 14 RFOUT RF Output. This pin is ac-coupled, but has a large resistor to GND for ESD protection, and matched to 50 Ω. See Figure 7 for the interface schematic. EPAD (GND) Exposed Pad (Ground). The exposed pad must be connected to RF/dc ground. See Figure 3 for the interface schematic.
