range. This nominally .5 micron
gate length GaAs FET is an
interdigitated four-cell structure
using airbridge interconnects
between source fingers. Total gate
periphery is 5 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.
