AT-41532

General Purpose, Low Current NPN Silicon Bipolar Transistor

Data Sheet

Description

Avago’s AT-41532 is a general purpose NPN bipolar transis-

tor that has been optimized for maximum ft at low voltage

operation, making it ideal for use in battery powered

applications in cellular/PCS and other wireless markets.

The AT-41532 uses the miniature 3-lead SOT-323 (SC-70)

plastic package.

Optimized performance at 5 V makes this device ideal

for use in 900 MHz, 1.8 GHz, and 2.4 GHz systems. Typical

amplifier design at 900 MHz yields 1 dB NF and 15.5 dB as-

sociated gain at 5 V and 5 mA bias. High gain capability

at 1 V and 1 mA makes this device a good fit for 900 MHz

pager applications. A good noise match near 50 ohms at

900 MHz makes this a very user-friendly device. Moreover,

voltage breakdowns are high enough to support operation

at 10 V.

The AT-41532 belongs to Avago’s AT-4XXXX series bipolar

transistors. It exhibits excellent device uniformity, per-

formance, and reliability as a result of ion-implantation,

self-alignment techniques, and gold metalization in the

fabrication process.
