1, 4, 5, 8, 9, NIC Not Internally Connected. However, all data shown was measured with these pins connected to RF/dc ground 12, 13, 16 externally. 2, 11 GND Ground. Connect these pins to RF/dc ground. See Figure 3 for the interface schematic. 3 RFIN RF Input. This pin is ac-coupled and matched to 50 Ω. See Figure 4 for the interface schematic. 6, 7 V , V Optional Gate Controls for the Amplifier. If left open, the amplifier runs self biased at the standard current. GG1 GG2 Applying a negative voltage reduces the drain current. External capacitors are required (see Figure 24). See Figure 5 for the interface schematic. 10 RFOUT RF Output. This pin is ac-coupled and matched to 50 Ω. See Figure 6 for the interface schematic. 14, 15 V , V Power Supply Voltages for the Amplifier. See assembly for the required external components (see Figure 23 DD1 DD2 and Figure 24). See Figure 7 for the interface schematic. EPAD Exposed Pad. The package bottom has an exposed metal ground paddle that must connect to RF/dc ground.
