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.
