Description
Hewlett-Packard’s AT-41486 is a
general purpose NPN bipolar
transistor that offers excellent
high frequency performance. The
AT-41486 is housed in a low cost
surface mount .085" diameter
plastic package. The 4 micron
emitter-to-emitter pitch enables
this transistor to be used in many
different functions. The 14 emitter
finger interdigitated geometry
yields an intermediate sized
transistor with impedances that
are easy to match for low noise
and moderate power applications.
Applications include use in
wireless systems as an LNA, gain
stage, buffer, oscillator, and
mixer. An optimum noise match
near 50 Ω at 900 MHz, makes this
device easy to use as a low noise
amplifier.
The AT-41486 bipolar transistor is
fabricated using Hewlett-Packard’s
10 GHz f_T Self-Aligned-Transistor
(SAT) process. The die is 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 this device.
