Package
Description
The AT-64020 is a high perfor-
mance NPN silicon bipolar
transistor housed in a hermetic
BeO disk package for good
thermal characteristics. This
device is designed for use in
medium power, wide band
amplifier and oscillator applica-
tions operating over VHF, UHF
and microwave frequencies.
200 mil BeO Package
Excellent device uniformity,
performance and reliability are
produced by the use of ion-
implantation, self-alignment
techniques, and gold metallization
in the fabrication of these devices.
The use of ion-implanted ballast
resistors ensures uniform current
distribution through the multiple
emitter fingers.
