Description

1

RBIAS

Bias Setting Resistor. Connect a resistor between RBIAS and VDD to set IDQ. See the typical application circuit (see Figure 100) and

Table 12 to Table 15 for more details. See Figure 7 for the interface schematic.

2

VTEMP

Temperature Sensor Output Voltage. See Figure 5 for the interface schematic.

3, 6

GND

Ground. Connect the GND pins to a ground plane that has low electrical and thermal impedance. See Figure 3 for the interface schematic.

4

RFIN

RF Input. RFIN is AC-coupled and matched to 50Ω. See Figure 4 for the interface schematic.

5

RFOUT

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

7

VENBL

Device Enable. An active high digital signal enables the device, and an active low digital signal disables the device. See Figure 8 for the

interface schematic.

8

VDD

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

GROUND PADDLE

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