ULTRA LOW NOISE
PSEUDOMORPHIC HJ FET
NE32400
FEATURES
• VERY LOW NOISE FIGURE:
NF = 0.6 dB typical at f = 12 GHz
• HIGH ASSOCIATED GAIN:
GA = 11.0 dB typical at f = 12 GHz
• LG = 0.25 µm, WG = 200 µm
DESCRIPTION
The NE32400 is a pseudomorphic Hetero-Junction FET chip
that utilizes the junction between Si-doped AlGaAs and undoped
InGaAs to create a two-dimensional electron gas layer with
very high electron mobility. This device features mushroom
shaped TiAl gates for decreased gate resistance and im-
proved power handling capabilities. The mushroom gate re-
sults in lower noise figure and high associated gain for con-
sumer and industrial applications.
NEC's stringent quality assurance and test procedures assure
the highest reliability and performance.
