Description

1

RBIAS

Bias Setting Resistor. Connect a resistor between RBIAS and VDD to set the IDQ. See the ADL8142-2CHIP data

sheet for more details.

2, 4, 5, 7

GND

Ground. Connect the GND pins to a ground plane that has low electrical and thermal impedance.

3

RFIN

RF Input. The RFIN pin is AC-coupled and matched to 50 Ω.

6

RFOUT

RF Output. The RFOUT pin is AC-coupled and matched to 50 Ω. The RF output path is AC-coupled, but there is

also a DC path to ground on the RFOUT side of the AC coupling capacitor.

8

VDD

Drain Bias. Connect the VDD pin to the supply voltage.

Die Bottom

GND

Die bottom must be connected to RF and DC ground.
