AT-42086
Up to 6 GHz Medium Power
Silicon Bipolar Transistor
Data Sheet
Description
Avago’s AT-42086 is a general purpose NPN bipolar tran-
sistor that offers excellent high frequency performance.
The AT-42086 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 20 emitter finger interdigitated geometry
yields a medium sized transistor with impedances that are
easy to match for low noise and medium power applica-
tions. Applications include use in wireless systems as an
LNA, gain stage, buffer, oscillator, and mixer. An optimum
noise match near 50Ω up to 1 GHz, makes this device easy
to use as a low noise amplifier.
The AT-42086 bipolar transistor is fabricated using Avago’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.
