DATA SHEET
N-CHANNEL GaAs HJ-FET
NE651R479A
0.4 W L-BAND POWER GaAs HJ-FET
DESCRIPTION
The NE651R479A is a 0.4 W GaAs HJ-FET designed for middle power transmitter applications for mobile
communication and wireless PC LAN systems. It is capable of delivering 0.4 W of output power (CW) with high linear
gain, high efficiency and excellent distortion and as a driver amplifier for our NE6510179A and NE6510379A.
Reliability and performance uniformity are assured by NEC鈥檚 stringent quality and control procedures.
