Silicon Bipolar Transistor
Data Sheet
Description
Avagoâs AT-32011 and AT-32033 are high performance
NPN bipolar transistors that have been optimized for
maximum ft at low voltage operation, making them ideal
for use in battery powered applications in wireless mar-
kets. The AT-32033 uses the 3 lead SOTâ23, while the AT-
32011 places the same die in the higher performance 4
lead SOT-143. Both packages are industry standard, and
compatible with high volume surface mount assembly
techniques.
The 3.2 micron emitter-to-emitter pitch and reduced
parasitic design of these transistors yields extremely high
performance products that can perform a multiplicity
of tasks. The 20 emitter finger interÂdigitated geometry
yields an easy to match to and extremely fast transistor
with moderate power, low noise resistance, and low op-
erating currents.
Optimized performance at 2.7 V makes these devices
ideal for use in 900 MHz, 1.8 GHz, and 2.4 GHz battery
operated systems as an LNA, gain stage, buffer, oscillaÂ
tor, or active mixer. Typical amplifier designs at 900 MHz
yield 1.2 dB noise figures with 12 dB or more associated
gain at a 2.7 V, 2 mA bias, with noise performance being
relatively insensitive to input match. High gain capabil-
ity at 1 V, 1 mA makes these devices a good fit for 900
MHz pager applications. Voltage breakdowns are high
enough for use at 5 volts.
The AT-3 series bipolar transistors are fabricated using
an optimized version of Avagoâs 10 GHz ft, 30 GHz fMAX
Self-Aligned-Transistor (SAT) process. The die are nitride
passivated for surface protection. Excellent device uni-
formity, performance and reliability are produced by the
use of ion-implantation, self-alignment techniques, and
gold metalization in the fabrication of these devices.
