AT-42085

Up to 6 GHz Medium Power Silicon Bipolar Transistor

Data Sheet

Description

Avago’s AT-42085 is a general purpose NPN bipolar

transistor that offers excellent high frequency

performance. The AT-42085 is housed in a low cost .085"

diameter plastic package. T he 4 micron emitter-to-emitter

pitch enables this transistor to be used in many different

functions. The 20 emitter finger interdigitated geometry

yields a medium sized transistor with impedances that

are easy to match for low noise and medium power

applications. Applications include use in wireless systems

as an LNA, gain stage, buffer, oscillator, and mixer. An

optimum noise match near 50Ω up to 1 GHz, makes this

device easy to use as a low noise amplifier.

The AT-42085 bipolar transistor is fabricated using Avago’s

10 GHz fT Self-Aligned-Transistor (SAT) process. The die is

nitride passivated for surface protection. Excellent 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.
