| 2-18 GHz Low Noise Gallium Arsenide FET Technical Data ATF-13100 Features * Low Noise Figure: 1.1 dB Typical at 12 GHz * High Associated Gain: 9.5 dB Typical at 12 GHz * High Output Power: 17.5 dBm Typical P1 dB at 12 GHz 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 300C 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. Chip Outline D S G S Description The ATF-13100 is a high performance gallium arsenide Schottkybarrier-gate field effect transistor chip. This device is designed for use in low noise, wideband amplifier and oscillator applications in the 2-18 GHz frequency range.

Permanent damage may occur if any of these limits are exceeded. 2. TMOUNTING SURFACE = 25C. 3. Derate at 4 mW/C for TMOUNTING SURFACE > 119C. 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.
