MITSUBISHI SEMICONDUCTOR <GaAs FET>
MGF431xG
Super Low Noise InGaAs HEMT
DESCRIPTION
The MGF431xG series super-low-noise HEMT(High Electron
Mobility Transistor) is designed for use in L to K band amplifiers.
The hermetically sealed metal-ceramic package assures
minimum parasitic losses, and has a configuration suitable for
microstrip circuits.

making semiconductor products better and more reliable,
but there is always the possibility that trouble may occur
with them.Trouble with semiconductors may lead to personal
injury, fire or property damage. Remember to give due
consideration to safety when making your circuit designs,
with appropriate measures such as (i)placement of
substitutive, auxiliary circuits, (ii)use of non-flammable
material or (iii)prevention against any malfunction or mishap.
