Data Sheet
Description
Avago’s AT-32011 and AT-32033 are high performance
NPN bipolar transistors that have been optimized for
maximum f_t at low voltage operation, making them ideal
for use in battery powered applications in wireless mar-
kets. The AT-32033 uses the 3 lead SOT‑23, 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 inter­digitated 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, oscilla­
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 Avago’s 10 GHz f_t, 30 GHz f_MAX
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.
