Description

1

RFIN

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

2, 3, 4

NIC

No Internal Connection. The NIC pins are not connected internally. For normal operation, connect the NIC pins to a ground plane that

has low electrical and thermal impedance.

5

RFOUT

RF Output. The RFOUT pin is ac-coupled and matched to 50 Ω. See Figure 4 for the interface schematic.

6

GND

Ground. Connect the GND pin to a ground plane that has low electrical and thermal impedance. See Figure 6 for the interface

schematic.

7

VDD

Drain Bias. Connect the VDD pin to the supply voltage. See Figure 4 for the interface schematic.

8

RBIAS

Bias Setting Resistor. Connect a resistor between RBIAS and VDD to set IDQ. See Table 9 and Figure 74 for more details. See

Figure 3 for the interface schematic.

EXPOSED

PADDLE

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