Description
The ATF-25570 is a high perfor-
mance gallium arsenide Schottky-
barrier-gate field effect transistor
housed in a hermetic, high reliabil-
ity package. This device is
designed for use in general
purpose amplifier and oscillator
applications in the 0.5-10 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.
