AT-41486
Up to 6 GHz Low Noise Silicon Bipolar Transistor
Data Sheet
Description
Avago’s AT-41486 is a general purpose NPN bipolar tran-
sistor that offers excellent high frequency performance.
The AT-41486 is housed in a low cost surface mount
.085" diameter plastic package. The 4 micron emitter-to-
emitter pitch enables this transistor to be used in many
different functions. The 14 emitter finger interdigitated
geometry yields an intermediate sized transistor with
impedances that are easy to match for low noise and
moderate power applications. Applications include use
in wireless systems as an LNA, gain stage, buffer, oscil-
lator, and mixer. An optimum noise match near 50 Ω at
900 MHz, makes this device easy to use as a low noise
amplifier.
The AT-41486 bipolar transistor is fabricated using
Avago’s 10 GHz f_T Self-Aligned-Transistor (SAT) process.
The die is 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
this device.
