Description
Hewlett Packard’s AT-31625 is a
low cost, NPN medium power
silicon bipolar junction transistor
housed in a miniature, MSOP-3
surface mount plastic package.
The AT-31625 can be used as a
driver device or an output device,
depending on the specific application. The AT-31625 features
+28␣ dBm CW output power when
operated at 4.8 volts. Excellent
gain and superior efficiency make
the AT-31625 ideal for use in
battery powered systems.
The AT-31625 is fabricated with
Hewlett Packard’s 10 GHz Ft SelfAligned-Transistor (SAT) process.
The die are nitride passivated for
surface protection. Excellent
device uniformity, performance
and reliability are produced by the
use of ion-implantation, selfalignment techniques, and gold
metalization in the fabrication of
these devices.
