DESCRIPTION
The NE76118 is a low cost gallium arsenide metal semicon-
ductor field effect transistor housed in a miniature (SOT-343)
plastic surface mount package. The device is fabricated using
ion implantation for improved RF and DC performance, reli-
ability, and uniformity. Its low noise figure, high gain, small
size and weight make it an ideal low noise amplifier transistor
in the 1-4 GHz frequency range. The NE76118 is suitable for
GPS, PCS, WLAN, MMDS, TVRO, and other commercial
applications.
NEC's stringent quality assurance and test procedures en-
sure the highest reliability and performance.

Note:
1. Typical values of noise figures and associated gain are those obtained when 50% of the devices from a large number of lots were individually
measured in a circuit with the input individually tuned to obtain the minimum value. Maximum values are criteria established on the production line
as a "go-no-go" screening test with the fixture tuned for the "generic" type but not for each specimen.
