Description

1

RBIAS

Bias Setting Resistor. Connect a resistor between RBIAS and VDD to set the IDQ. See Figure 91 and Table 9 for more details. See

Figure 4 for the interface schematic.

2, 4, 5, 7

GND

Ground. Connect the GND pins to a ground plane that has low electrical and thermal impedance. See Figure 7 for the interface

schematic.

3

RFIN

RF Input. The RFIN pin is AC-coupled and matched to 50 Ω. See Figure 5 for the interface schematic.

6

RFOUT

RF Output. The RFOUT pin is AC-coupled and matched to 50 Ω. See Figure 6 for the interface schematic.

8

VDD

Drain Bias. Connect the VDD pin to the supply voltage. See Figure 6 for the interface schematic.

EXPOSED

PADDLE

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