Description
The ATF-26884 is a high performance gallium arsenide Schottkybarrier-gate field effect transistor
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.

Notes:
1. Permanent damage may occur if
any of these limits are exceeded.
2. TCASE TEMPERATURE = 25°C.
3. Derate at 3.3 mW/°C for
TCASE > 92.5°C.
4. The small spot size of this technique results in a higher, though
more accurate determination of θjc
than do alternate methods. See
MEASUREMENTS section for
more information.
