Description
The ATF-26836 is a high performance gallium arsenide Schottkybarrier-gate field effect transistor
housed in a cost effective
microstrip package. This device is
designed for use in oscillator
applications and general purpose
amplifier applications in the
2-16␣ GHz frequency range.
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.

4. Storage above +150°C may tarnish
the leads of this package 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 θ
