GaAs MES FET
NES1821B-30
30W L-BAND POWER GaAs FET
N-CHANNEL GaAs MES FET
DESCRIPTION
PACKAGE DIMENSIONS (UNIT: mm)
The NES1821B-30 is power GaAs FET which provides
high output power and high gain in the 1.8-2.1 GHz
24±0.3
band.
20.4
1.0±0.1
Internal input matching circuits are designed to
GATE
optimize performance. The device has a 0.8 mm gate
SOURCE
length for increased linear gain. To reduce thermal
resistance, the device uses PHS (Plated Heat Sink)
2.4
technology.
The device incorporates WSi (tungsten silicide) gate
for
high
reliability
and
SiO2
glassivation
17.4±0.3 8.0
for
R1.2
surface stability.

document.
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, customers 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 is "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 an NEC sales representative in advance.
Anti-radioactive design is not implemented in this product.
