Data Sheet
Description
Avago’s AT-30511 and AT-30533 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-30533 uses the 3 lead SOT‑23, while the AT-
30511 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 para-
sitic design of these transistors yields extremely high per-
formance products that can perform a mul­ti­plicity of tasks.
The 5 emitter finger interdigitated geometry yields an ex-
tremely fast transistor with high gain and low operating
currents.
Optimized performance at 2.7 V makes these devices
ideal for use in 900 MHz, 1.8 GHz, and 2.4 GHz battery op-
erated systems as an LNA, gain stage, buffer, oscil­la­tor, or
active mixer. Typical amplifier designs at 900 MHz yield
1.3 dB noise figures with 13 dB or more associated gain at
a 2.7 V, 1 mA bias. Voltage break­downs are high enough
for use at 5 volts. High gain capability at 1 V, 1 mA makes
these devices a good fit for 900 MHz pager appli­cations.
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.
