finger interdigitated geometry
yields a medium sized transistor
with impedances that are easy to
match for low noise and medium
power applications. This device is
designed for use in low noise,
wideband amplifier, mixer and
oscillator applications in the VHF,
UHF, and microwave frequencies.
An optimum noise match near

Excellent device uniformity,
performance and reliability are
produced by the use of ion-

techniques, and gold metalization
in the fabrication of this device.
