PRELIMINARY DATA SHEET
N-CHANNEL GaAs MES FET
NES1823P-30
30 W L-S BAND PUSH-PULL POWER GaAs MES FET
DESCRIPTION
The NES1823P-30 is a 30 W push-pull type GaAs MES FET designed for high power transmitter applications for
PCS, DCS and IMT 2000 base station systems. It is capable of delivering 30 watts of output power (CW) with high linear
gain, high efficiency and excellent distortion. Its primary band is 1.8 to 2.3 GHz, however with different matching, 60
MHz or less of instantaneous bandwidth can be achieved anywhere from 0.8 to 2.3 GHz. The device employs
0.9 µm Tungsten Silicide gates, via holes, plated heat sink, and silicon dioxide passivation for superior performance,
thermal characteristics, and reliability.
Reliability and performance uniformity are assured by NEC’s stringent quality and control procedures.
FEATURES
• Push-pull type N-channel GaAs MES FET
• High output power : 30 W TYP.
• High linear gain : 13 dB TYP.
• High power added efficiency: 40 % TYP. @VDS = 10 V, I
Dset
= 4 A, f = 2.2 GHz

CAUTION
The Great Care must be taken in dealing with the devices in this guide.
The reason is that the material of the devices is GaAs (Gallium Arsenide), which is
designated as harmful substance according to the law concerned.
Keep the law concerned and so on, especially in case of removal.

• Descriptions of circuits, software, and other related information in this document are provided for illustrative
purposes in semiconductor product operation and application examples. The incorporation of these circuits,

• 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: Aircraft, 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.
