GaAs MES FET
NE85002 SERIES
2 W C-BAND POWER GaAs FET
N-CHANNEL GaAs MES FET
Document No. P10969EJ1V0DS00 (1st edition)
Date Published June 1996 P
Printed in Japan
DESCRIPTION
The NE8500295 power GaAs FET covers 3.5 to 8.5 GHz frequency range with three different Class A, 2.0 W
partially matched devices. Each packaged device has an input lumped element matching network.
NE8500200 is the six-cells recessed gate chip used in ‘95’ package.
The device incorporates Ti-Al gate and silicon dioxide glassivation. To reduce the thermal resistance, the device
has a PHS. (Plated Heat Sink)
NEC’s strigent quality assurance and test procedures assure the highest reliability and performance.
FEATURES
• Class A operation
• High power output
• High reliability

CHIP HANDLING
DIE ATTACHMENT
Die attach can be accomplished with a Au-Sn (300 ±10 ˚C) performs in a forming gas environment. Epoxy die
attach is not recommended.
BONDING
Gate and drain bonding wires should be minimum length, semi-hard gold wire (3 - 8 % elongation) 30 microns or
less in diameter.
Bonding should be performed with a wedge tip that has a taper of approximately 15 %.
Die attach and bonding time should be kept to a minimum. As a general rule, the bonding operation should be
kept within a 280 ˚C _ 5 minute curve. If longer periods are required, the temperature should be lowered.
PRECAUTIONS
The user must operate in a clean, dry environment.
The chip channel is glassivated for mechanical protection only and does not preclude the necessity of a clean
environment.
The bonding equipment should be periodically checked for sources of surge voltage and should be properly
grounded at all times. In fact, all test and handling equipment should be grounded to minimize the possibilities of static
discharge.

NEC Corporation does not assume any liability for infringement of patents, copyrights or other intellectual
property rights of third parties by or arising from use of a device described herein or any other liability arising
from use of such device. No license, either express, implied or otherwise, is granted under any patents,
copyrights or other intellectual property rights of NEC Corporation or others.
While NEC Corporation has been making continuous effort to enhance the reliability of its semiconductor devices,
the possibility of defects cannot be eliminated entirely. To minimize risks of damage or injury to persons or
property arising from a defect in an NEC semiconductor device, customer must incorporate sufficient safety
measures in its design, such as redundancy, fire-containment, and anti-failure features.
NEC devices are classified into the following three quality grades:
“Standard“, “Special“, and “Specific“. The Specific quality grade applies only to devices developed based on
a customer designated “quality assurance program“ for a specific application. The recommended applications
of a device depend on its quality grade, as indicated below. Customers must check the quality grade of each
device before using it in a particular application.
Standard: Computers, office equipment, communications equipment, test and measurement equipment,
audio and visual equipment, home electronic appliances, machine tools, personal electronic
equipment and industrial robots
Special: Transportation equipment (automobiles, trains, ships, etc.), traffic control systems, anti-disaster
systems, anti-crime systems, safety equipment and medical equipment (not specifically designed
for life support)
Specific: Aircrafts, aerospace equipment, submersible repeaters, nuclear reactor control systems, life
support systems or medical equipment for life support, etc.
The quality grade of NEC devices in “Standard“ unless otherwise specified in NEC's Data Sheets or Data Books.
If customers intend to use NEC devices for applications other than those specified for Standard quality grade,
they should contact NEC Sales Representative in advance.
Anti-radioactive design is not implemented in this product.
