AT-41511, AT-41533
General Purpose, Low Noise NPN
Silicon Bipolar Transistors
Data Sheet
Description
Avago’s AT-41511 and AT-41533 are general purpose NPN
bipolar transistors that offer excellent high frequency
performance at an economical price. The AT-41533 uses
the 3 lead SOT-23, while the AT-41511 places the same
die in the lower parasitic 4 lead SOT-143. Both packages
are industry standard, and compatible with high volume
surface mount assembly techniques.
The 4 micron emitter-to-emitter pitch of these transistors
yields high performance products that can perform a
multiplicity of tasks. The 14 emitter finger interdigitated
geometry yields an intermediate-sized transistor with easy
to match to impedances, low noise figure, and moderate
power.
Optimized for best performace from a 5 to 8 volt bias
supply, these transistors are also good performers at 2.7
V. Applications include use in wireless systems as an LNA,
gain stage, buffer, oscillator, or active mixer.
An optimum noise match near 50 ohms at 900 MHz makes
these devices particularly easy to use as LNAs. Typical ampli-
fier designs at 900 MHz yield 1 dB noise figures with 15 dB
or more associated gain at a 5 V, 5 mA bias, with good gain
and noise figure obtainable at biases as low as 2 mA.
The AT-415 series bipolar transistors are fabricated using
Avago’s 10 GHz fT Self-Aligned-Transistor (SAT) process.
The die are nitride passivated for surface protection. Ex-
cellent device uniformity, performance and reliability are
produced by the use of ion-implantation, self-alignment
techniques, and gold metalization in the fabrication of
these devices.
