Description

1

RFIN

RF Input. The RFIN pin is DC-coupled and matched to 50 Ω. See Figure 3 for the interface schematic.

2, 3

NIC

No Internal Connection. The NIC pins are not connected internally. For normal operation, connect these pins to ground.

4

GND

Ground. Connect to a ground plane that has low electrical and thermal impedance. See Figure 4 for the interface schematic.

5

RFOUT/VCC1

RF Output and Collector Bias Voltage. RFOUT is DC-coupled and also serves as the collector biasing node. For the collector bias (VCC1),

connect a DC bias network to provide the collector current (ICC) and AC-couple the RF output path. See Figure 5 for the interface schematic.

6

VCC2

Collector Bias. Connect VCC2 to a common supply with VCC1. See Figure 6 for the interface schematic.

7

RBIAS

Bias Setting Resistor. Connect a resistor between the RBIAS pin and VCC1 and VCC2 pins to set ICQ. See Figure 82 and Table 9 for more

details. See Figure 7 for the interface schematic.

8

VBIAS

Bias Setting Voltage Output. VBIAS sets the bias voltage for the RFIN pin. Connect VBIAS to RFIN using an inductor or ferrite bead as shown

in Figure 82. See Figure 8 for the interface schematic

GROUND

PADDLE

Ground Paddle. Connect the ground paddle to a ground plane that has low electrical and thermal impedance.
