DESCRIPTION
Ga
16
The NE425S01 is a Hetero-Junction FET that utilizes the hetero
junction to create high mobility electrons. Its excellent low noise
and high associated gain make it suitable for DBS and other
commercial applications.
NEC's stringent quality assurance and test procedures assure
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 tuned for the "generic" type but not each specimen.
