Description
The ATF-46171 is a gallium
arsenide Schottky-barrier-gate
field effect transistor designed for
medium power, linear amplifica-
tion in the 2 to 10 GHz frequency
range. This nominally 0.5 micron
gate length GaAs FET is an
interdigitated four-cell structure
using airbridge interconnects
between drain fingers. Total gate
periphery is 1.25 millimeters.
Proven gold based metallization
systems and nitride passivation
assure a rugged, reliable device.
This device is suitable for applica-
tions in space, airborne, military
ground and shipboard, and
commercial environments. It is
supplied in a hermetic high
reliability package with low
parasitic reactance and minimum
thermal resistance.
