AT-42000
Up to 6 GHz Medium Power Silicon Bipolar Transistor Chip
Data Sheet
CAUTION: It is advised that normal static precautions be taken in handling and assembly
of this component to prevent damage and/or degradation which may be induced by ESD.
Description
Avago’s AT-42000 is a general purpose NPN bipolar transis-
tor chip that offers excellent high frequency performance.
The 4 micron emitter-to-emitter pitch enables this transis-
tor to be used in many different functions. The 20 emit-
ter finger interdigitated geometry yields a medium sized
transistor with impedances that are easy to match for low
noise and medium power applications.
This device is designed for use in low noise, wideband am-
plifier, mixer and oscillator applications in the VHF, UHF,
and microwave frequencies. An optimum noise match
near 50W up to 1 GHz , makes this device easy to use as a
low noise amplifier.
The AT-42000 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 ionimplantation, self-alignment techniques,
and gold metalization in the fabrication of this device.
The recommended assembly procedure is gold-eutectic
die attach at 400oC and either wedge or ball bonding us-
ing 0.7 mil gold wire. See APPLICATIONS section, “Chip
Use”.
