ATF-10236
36 micro-X PackageDescription
The ATF-10236 is a high performance
gallium arsenide Schottky-barrier-
gate field effect transistor housed in a
cost effective microstrip package. Its
low noise figure makes this device
appropriate for use in the first and
second stages 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 using airbridge
interconnects between drain fingers.
Total gate periphery is 500 microns.
Proven gold based metallization
systems and nitride passivation
assure a rugged, reliable device.
