This GaAs FET device has a
nominal 0.3 micron gate length
with a total gate periphery of
250␣ microns. Proven gold based
metallization systems and nitride
passivation assure a rugged,
reliable device.
The recommended mounting
procedure is to die attach at a
stage temperature of 300° C using
a gold-tin preform under forming
gas. Assembly can be preformed
with either wedge or ball bonding
using 0.7 mil gold wire. See also
“Chip Use” in the APPLICATIONS
section.
