Notes:
1. Permanent damage may occur if any of these limits are exceeded.
2. TCASE TEMPERATURE = 25°C.
3. Derate at 4 mW/°C for TCASE > 25°C.
4. The small spot size of this technique results in a higher, though more accurate determination of jc than do alternate methods. See MEASUREMENTS section for more information.
The ATF-21170 is a high performance gallium arsenide Schottkybarrier- gate field effect transistor housed in a hermetic, high reliability package. This device is designed for use in low noise or medium power amplifier applications in the 0.5-6 GHz frequency range.
This GaAs FET device ATF-21170 has a nominal 0.3 micron gate length with a total gate periphery of 750Êmicrons. Proven gold based metallization systems and nitride passivation assure a rugged, reliable device.
