DESCRIPTION
The NE434S01 is a Hetero-Junction FET that uses the junction
between Si-doped AlGaAs and undoped InGaAs to create very
high mobility electrons. Its excellent low noise and high asso-
ciated gain make it suitable for TVRO and other commercial
systems.

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.
