PRELIMINARY DATA SHEET
N-CHANNEL GaAs MES FET
NES2427P-45
45 W S-BAND PUSH-PULL POWER GaAs MES FET
DESCRIPTION
The NES2427P-45 is a 45 W push-pull type GaAs MES FET designed for high power transmitter applications for
WLL repeater and base station systems. It is capable of delivering 45 W of output power (CW) with high linear gain,
high efficiency and excellent distortion under the condition of 12 V operation. Its primary band is 2.4 to 2.7 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
• VDS = 12.0 V operation
• High output power: Pout = 45 W TYP.
• High linear gain: GL = 11 dB TYP.
• High power added efficiency: ηadd = 41 % TYP. @ VDS = 12.0 V, IDset = 4.0 A (total), f = 2.70 GHz

• While NEC endeavours to enhance the quality, reliability and safety of NEC semiconductor products, customers
agree and acknowledge that the possibility of defects thereof cannot be eliminated entirely. To minimize
risks of damage to property or injury (including death) to persons arising from defects in NEC
semiconductor products, customers must incorporate sufficient safety measures in their design, such as

• NEC semiconductor products are classified into the following three quality grades:
"Standard", "Special" and "Specific". The "Specific" quality grade applies only to semiconductor products
developed based on a customer-designated "quality assurance program" for a specific application. The
recommended applications of a semiconductor product depend on its quality grade, as indicated below.
Customers must check the quality grade of each semiconductor product 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 and medical equipment for life support, etc.
The quality grade of NEC semiconductor products is "Standard" unless otherwise expressly specified in NEC's
data sheets or data books, etc. If customers wish to use NEC semiconductor products in applications not
intended by NEC, they must contact an NEC sales representative in advance to determine NEC's willingness
to support a given application.
(Note)
(1) "NEC" as used in this statement means NEC Corporation and also includes its majority-owned subsidiaries.
(2) "NEC semiconductor products" means any semiconductor product developed or manufactured by or for
NEC (as defined above).
