| 0.5 - 12 GHz Low Noise Gallium Arsenide FET Technical Data ATF-10100 Features * Low Noise Figure: 0.5 dB Typical at 4 GHz * Low Bias: VDS = 2 V, IDS = 25 mA * High Associated Gain: 14.0 dB Typical at 4 GHz * High Output Power: 21.0 dBm Typical P1 dB at 4 GHz chip. Its premium noise figure makes this device appropriate for use in the first stage of low noise amplifiers operating in the 0.5-12 GHz frequency range. This GaAs FET device has a nominal 0.3 micron gate length interconnects between drain fingers. Total gate periphery is 500 microns. Proven gold based metallization systems and nitride passivation assure a rugged, reliable device.

Permanent damage may occur if any of these limits are exceeded. 2. TCASE TEMPERATURE = 25C. 3. Derate at 4.4 mW/C for TCASE > 78C. 4. The small spot size of this technique results in a higher, though more accurate determination of jc than do alternate methods. See APPLICATIONS PRIMER IIIA for more information.
