ULTRA LOW NOISE
PSEUDOMORPHIC HJ FET _NE24200
(SPACE QUALIFIED)
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 NE24200 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 improved power handling capabilities. The mushroom
gate results in lower noise figure and high associated gain for
space applications.
NEC's stringent quality assurance and test procedures as-
sure the highest reliability and performance.
