Description

RBIAS

Current Mirror Bias Resistor. Use the RBIAS pin via the external resistor (R2, see Figure 71) to set the current to the

internal resistor. See Figure 3 for the interface schematic.

RFIN

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

3, 4

GND

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

RFOUT/VDD

RF Output/Drain Bias for the Amplifier. The RFOUT/VDD pin is dc-coupled and matched to 50 Ω. See Figure 5 for the

interface schematic.

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

EPAD

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