ULTRA LOW NOISE
PSEUDOMORPHIC HJ FET NE24283B
(SPACE QUALIFIED)
FEATURES
• VERY LOW NOISE FIGURE:
0.6 dB TYP at 12 GHz
• HIGH ASSOCIATED GAIN:
11.0 dB TYP at 12 GHz
• GATE LENGTH: 0.25 µm
• GATE WIDTH: 200 µm
• HERMETIC METAL/CERAMIC PACKAGE
DESCRIPTION
The NE24283B is a pseudomorphic Hetero-Junction FET that
uses the junction between Si-doped AlGaAs and undoped
InGaAs to create very high mobility electrons. The device
features mushroom shaped TiAl gates for decreased gate
resistance and improved power handling capabilities. The
mushroom gate also results in lower noise figure and high
associated gain. This device is housed in a solder sealed
hermetic, metal ceramic package for high reliability in space
applications.

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 of the production
line as a "go-no-go" screening tuned for the "generic" type but not for each specimen.
