Pad Descriptions

Name

Description

RFIN

RF input pad. This pad is AC coupled.

RFOUT

RF output pad. This pad is AC coupled.

VD		

Drain Voltage pad.

VG		Gate Voltage pad.

VC		

Voltage phase control pad.

BOTTOM

The die backside must be connected to RF/DC ground.

General Notes on Assembly

Die should be mounted on conductive material such as gold-plated metal to provide agood ground and suitable heat sink, if necessary.
1.

Attaching the die using Au/Sn preforms is preferable. The Eutectic melt for Au/
Sn occurs at approximately 280oC so the die (plus mount and preform) is initiallyheated up to 180oC and then it is heated for approximately 10 seconds to 280oC
using a nitrogen heat gun. The device will survive 10 seconds at this temperature.
The static breakdown for GaAs devices is approximately 330oC.

2.

Pure, dry nitrogen should be used as the heat source.

3.

If the devices cannot be lifted/ placed by a vacuum device, then ESD die-lifting
tweezers are preferable.

4.

Aluminium wire must not be used.
