Description

RBIAS

Current Mirror Bias Resistor Pin. Use this pin to set the current to the internal resistor by the external resistor. See

Figure 3 for the interface schematic.

RFIN

RF Input (RFIN). This pin is ac-coupled and matched to 50 Ω. See Figure 4 for the interface schematic.

3, 4

No Connect. This pin is not connected internally. This pin must be connected to the RF and dc ground.

RFOUT/VDD

RF Output (RFOUT). This pin is ac-coupled and matched to 50 Ω. See Figure 5 for the interface schematic.

Drain Bias for the Amplifier (VDD). This pin is ac-coupled and matched to 50 Ω. See Figure 5 for the interface

schematic.

GND

Ground. This pin must be connected to the RF and dc ground. See Figure 6 for the interface schematic.

EPAD

Exposed Pad. The exposed pad must be connected to RF and dc ground.
