DESCRIPTION
The NE76084S provides a low noise figure and high associ-
ated gain through 14 GHz. The NE76084S device is fabri-
cated by ion implantation for improved RF and DC perfor-
mance, reliability, and uniformity. The device features a
recessed 0.3 micron gate and triple epitaxial technology.
NEC's stringent quality assurance and test procedures assure
the highest reliability and performance.

Notes:
1. Typical values of noise figures 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.
2. Package type 84S recommended for use below 13 GHz. Refer to NE76083A for use above 13 GHz.
