2–16 GHz Low Noise Gallium Arsenide FET Technical Data ATF-13736 Features Description • Low Noise Figure: 1.8␣ dB Typical at 12␣ GHz The ATF-13736 is a high performance gallium arsenide Schottkybarrier-gate field effect transistor housed in a cost effective microstrip package. Its noise figure makes this device appropriate for use in the gain stages of low noise amplifiers operating in the 2-16 GHz frequency range. • High Associated Gain: 9.0␣ dB Typical at 12␣ GHz • High Output Power: 17.5␣ dB Typical at 12␣ GHz • Cost Effective Ceramic Microstrip Package • Tape-and-Reel Packaging Option Available[1] 36 micro-X Package 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.

Permanent damage may occur if any of these limits are exceeded. 2. TCASE TEMPERATURE = 25°C. 3. Derate at 2.5 mW/°C for TCASE > 85°C. 4. Storage above +150°C may tarnish the leads of this package making it difficult to solder into a circuit. After a device has been soldered into a circuit, it may be safely stored up to 175°C. 5. 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.
