NEC's L TO Ku BAND LOW NOISE NE67400
AMPLIFIER N-CHANNEL GaAS MESFET NE67483B
FEATURES
• LOW NOISE FIGURE:
NF = 1.4 dB TYP at f = at 12 GHz
• HIGH ASSOCIATED GAIN:
GA = 10 dB TYP at f = 12 GHz
• GATE WIDTH: WG = 280 µm
• GATE LENGTH: LG = 0.3 µm
DESCRIPTION
NEC's NE674 is a L to Ku Band low noise GaAs MESFET. This
device features a low noise figure with high associated gain,
employing a recessed 0.3 micron gate and triple epitaxial
technology. The active area of the chip is covered with SiD2
and Si3N4 for scratch protection and surface stability. This
device is suitable for both amplifier and oscillator applications.
This device is housed in a solder sealed hermetic, metal
ceramic package for high reliability in space applications.
