Description
Hewlett Packard’s AT-38086 is a
low cost, NPN silicon bipolar
junction transistor housed in a
surface mount plastic package.
This device is designed for use as
a pre-driver or driver device in
applications for cellular and
wireless communications
markets. At 4.8 volts, the
AT-38086 features +28 dBm pulsed
output power, Class AB operation,
and +23.5␣ dBm CW. Superior
efficiency and gain makes the
AT-38086 an excellent choice for
battery powered systems.
The AT-38086 is fabricated with
Hewlett Packard’s 10 GHz Ft Self-
Aligned-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, self-
alignment techniques, and gold
metalization in the fabrication of
these devices.
