AT-41500
Up to 6 GHz Low Noise Silicon Bipolar Transistor Chip
Data Sheet
Description/Applications
The AT-41500 of Avago Techologies is a general purpose
NPN bipolar transistor chip that offers excellent high
frequency performance. The 4 micron emitter-to-emitter
pitch enables this transistor to be used in many different
functions. The 15 emitter fingers interdigitated geometry
yields an intermediate sized transistor with impedances
that are easy to match for low noise and moderate power
applications. This device is designed for use in low noise,
wideband amplifier, mixer and oscillator applications in
the VHF, UHF, and microwave frequencies. An optimum
noise match near 50 Ω at 1GHz, makes this device easy
to use as a low noise amplifier.
The AT-41500 bipolar transistor is fabricated using Avago
Technologies’ 10 GHz fT Self-Aligned-Transistor (SAT)
process. The die is nitride passivated for surface pro-
tection. Excellent device uniformity, performance and
reliability are produced by the use of ion implantation,
self-alignment techniques, and gold metallization in the
fabrication of this device.
