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 fT 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.
